Description
本発明は、環境汚染物質の検出材およびその製造方法に関する。また、その検出材を用いた環境汚染物質の有無を評価する方法に関する。 The present invention relates to an environmental pollutant detection material and a method for manufacturing the same. The present invention also relates to a method for evaluating the presence or absence of an environmental pollutant using the detection material.
産業廃棄物の処理場や工場跡地などの土壌や水系は、重金属等（クロム、ヒ素、鉛、フッ素等）の環境汚染物質による汚染が懸念される土壌となっている場合がある。このような土壌は降雨などによりその汚染物質が周辺地域へ溶出拡散したりすることで、さらに汚染地域が拡大し広範囲な環境汚染が生じるおそれがあり、その浄化が求められている。 Soil and water systems such as industrial waste treatment plants and factory sites may be soils that are likely to be polluted by environmental pollutants such as heavy metals (chromium, arsenic, lead, fluorine, etc.). In such soil, the pollutants may elute and diffuse into the surrounding area due to rainfall, etc., which may further expand the contaminated area and cause a wide range of environmental pollution, and its purification is required.
汚染土壌や水系の浄化を行うためには、各環境汚染物質の有無および汚染源の特定が必要であるが、そのためには、汚染が予測される広範囲な面積を対象とした土壌の採取とその分析が必要となる。ＪＩＳ Ｋ０１０２（非特許文献１）は、広く工場排水試験方法に関する規格であり、土壌汚染の程度を評価するに当たってもこれに準じた試験方法が行われている。このＪＩＳ規格の評価方法では、フッ素（３４．項）については、ランタン−アリザリンコンプレキソン吸光光度法、イオン電極法、イオンクロマトグラフ法、流れ分析法が開示されているが、これらは吸光光度計等を準備し、測定前の煩雑な処理を必要とするものであった。 In order to purify contaminated soil and water systems, it is necessary to identify the presence of each environmental pollutant and the source of the contamination. For this purpose, soil collection and analysis over a wide area where contamination is predicted is required. Is required. JIS K0102 (Non-Patent Document 1) is a standard widely related to factory drainage test methods, and test methods according to this are performed even when evaluating the degree of soil contamination. In this JIS standard evaluation method, lanthanum-alizarin complexone absorptiometry, ion electrode method, ion chromatograph method and flow analysis method are disclosed for fluorine (section 34.). And the like, and complicated processing before measurement is required.
同様に、ＪＩＳ Ｋ０１０２においては、ホウ素（Ｂ）（４７．項）の評価方法としては、メチレンブルー吸光光度法等、鉛（５４．項）の評価方法としては、フレーム原子吸光法等が開示されており、いずれも、厳密な定量を目的とするものが多く、特別な測定装置、測定前の処理を行う必要があり、高度な評価技術を必要とするものであった。大型の装置を用いることなく簡便に環境調査を行うために、例えば特許文献１には、シリカ粒子と色素分子を複合化した水中六価クロム検知材が開示されている。しかしながら、特許文献１に開示された技術が適用できる対象、使用できる環境は限られたものであり、様々な環境で多様な環境汚染物質等の分析を行うには十分なものではなかった。 Similarly, in JIS K0102, as an evaluation method of boron (B) (Section 47.), methylene blue absorptiometry and the like, and as an evaluation method of lead (Section 54.), flame atomic absorption method and the like are disclosed. In many cases, all of them are intended for strict quantification, and a special measuring device and processing before measurement are required, and advanced evaluation techniques are required. In order to conduct an environmental survey easily without using a large apparatus, for example, Patent Document 1 discloses a hexavalent chromium detection material in water in which silica particles and pigment molecules are combined. However, the object to which the technique disclosed in Patent Document 1 can be applied and the environment in which the technique can be used are limited, and it is not sufficient for analyzing various environmental pollutants in various environments.
また、特許文献２は、フッ素イオン含有試料をイオンクロマトグラフで分離した後、ランタン・アリザリンコンプレキソン反応試薬と反応させ、その反応物を分光光度検出器で検出することを特徴とするフッ素イオン分析方法に関するものである。ここでも、フッ素イオンの分析のために、イオンクロマトグラフを行い、分光光度検出器を用いる為、複雑な処理と、特別な装置を必要とするものである。 Patent Document 2 discloses a fluorine ion analysis characterized in that after a fluorine ion-containing sample is separated by an ion chromatograph, the sample is reacted with a lanthanum / alizarin complexone reaction reagent, and the reaction product is detected with a spectrophotometric detector. It is about the method. Here too, in order to analyze fluorine ions, ion chromatography is performed and a spectrophotometric detector is used, so that complicated processing and a special apparatus are required.
前述のように、従来公知の評価方法は、高度な評価技術を必要とするものであったが、時間や費用がかかるものであり、より現場で速やかな評価結果を得られる評価方法のニーズがある。かかる状況下、本願発明は、簡易な手法で、速やかに評価することができる検出材を提供することを目的とする。また、そのような検出材の製造方法を提供する。さらには、そのような検出材を用いた環境汚染物質の有無を評価する方法を提供するものである。 As described above, conventionally known evaluation methods require advanced evaluation techniques, but they are time consuming and expensive, and there is a need for an evaluation method that can obtain a quick evaluation result on site. is there. Under such circumstances, an object of the present invention is to provide a detection material that can be quickly evaluated by a simple method. Moreover, the manufacturing method of such a detection material is provided. Furthermore, the present invention provides a method for evaluating the presence or absence of an environmental pollutant using such a detection material.

Can do.

以下に本発明の実施の形態を詳細に説明するが、以下に記載する構成要件の説明は、本発明の実施態様の一例（代表例）であり、本発明はその要旨を超えない限り、以下の内容に限定されない。 DESCRIPTION OF EMBODIMENTS Embodiments of the present invention will be described in detail below. However, the description of the constituent elements described below is an example (representative example) of an embodiment of the present invention. It is not limited to the contents.
本発明は環境汚染物質の有無を評価する検出材であって、基材に発色剤溶液を担持させてなり、前記基材が吸収する発色剤溶液量が前記基材の重量に対して１５０重量％以上１００，０００重量％以下であることを特徴とする検出材である。このような検出材とすることで、簡易に環境汚染物質の有無を評価することができる。 The present invention is a detection material for evaluating the presence or absence of environmental pollutants, comprising a base material carrying a color former solution, and the amount of the color former solution absorbed by the base material is 150 weights with respect to the weight of the base material. % Or more and 100,000% by weight or less. By setting it as such a detection material, the presence or absence of an environmental pollutant can be evaluated easily.
これは、本発明の検出材に発色剤溶液を担持させることによるが、このような発色剤溶液を担持させた基材は、発色剤が所定の条件で対象となる汚染物質と反応することで発色し、その発色の有無によって目的とする汚染物質の有無やその程度を把握することができるものである。しかしながら、一般的にこの発色剤溶液に用いられている発色剤自体は、単独では結晶状の粉末、溶液等のものが多く、単独での取り扱い性が低い。または、実際の試験のための発色剤の必要量は微量であるのに対して、目視等で観察するために必要な量を、試験のたびに用いるには高価すぎたり、発色が強すぎて結果を観察しにくい場合がある。そのため、検出対象となる物質とは反応せず、その表面や内部に発色剤を分散担持させることができる基材に、目視観察等に適した量の発色剤を担持させたものを用いることが適している。 This is because the color developing agent solution is carried on the detection material of the present invention, and the substrate carrying such a color developing agent solution reacts with the target contaminant under predetermined conditions. The color is developed, and the presence or absence and the extent of the target pollutant can be grasped by the presence or absence of the color development. However, the color former itself generally used in this color former solution is often in the form of a crystalline powder, a solution, etc. alone, and the handleability alone is low. Alternatively, the amount of color former required for actual testing is very small, but the amount necessary for visual observation is too expensive or too strong to use for each test. It may be difficult to observe the results. For this reason, it is necessary to use a base material that does not react with the substance to be detected and can carry the color former on its surface or inside, with a color developer suitable for visual observation or the like. Is suitable.
本発明の検出材に用いられる基材は、基材が吸収する発色剤溶液量が前記基材の重量に対して（基材が吸収する発色剤溶液量／基材重量）１５０重量％以上１００，０００重量％以下であることを特徴とする基材である。ここで、基材が吸収する発色剤溶液量（基材が吸収する発色剤溶液量／基材重量）を、以下、単に「吸液量」と記載し、発色剤溶液を吸収する特性を「吸液性」と記載する場合がある。まず、本発明に用いられる基材は、発色剤溶液を、その基材の表面や内部に分散担持させることができるものである。また、その基材は、基材の重量に対して１５０重量％以上１００，０００重量％以下の発色剤溶液の担持量を有するものである。すなわち、基材として用いられるものは自重の１．５倍以上１０００倍以下の発色剤溶液を吸収することができるものである。これは、基材が自重を超える溶液を担持することであるが、このような基材を用いて検出材を作成することで、発色剤溶液を担持するのみでなく、さらに環境汚染物質の有無を評価しようとする液を吸収し、基材自身の表面や内部で発色反応が起こるため、使用時に適宜、この反応を所望の場所で行うことができるものである。 In the base material used for the detection material of the present invention, the amount of the color former solution absorbed by the base material is 150 wt% or more with respect to the weight of the base material (the amount of the color former solution absorbed by the base material / the base material weight). , 000% by weight or less. Here, the amount of the color former solution absorbed by the base material (the amount of the color former solution absorbed by the base material / the weight of the base material) is hereinafter simply referred to as “liquid absorption amount”. May be described as “liquid absorbency”. First, the base material used in the present invention is capable of dispersing and supporting the color former solution on the surface or inside of the base material. Further, the base material has a loading of the color former solution of 150% by weight to 100,000% by weight with respect to the weight of the base material. That is, what is used as the base material is capable of absorbing a color former solution having a weight of 1.5 to 1000 times its own weight. This means that the substrate carries a solution that exceeds its own weight. By creating a detection material using such a substrate, not only the color former solution is supported, but also the presence or absence of environmental pollutants. Since the color development reaction occurs on the surface or inside of the base material itself, the reaction can be appropriately performed at a desired place at the time of use.
この吸収する発色剤溶液量は、具体的には以下の方法で求めることができる。まず乾燥した基材の重量を測定した吸液前の基材を１００重量部とすると、この基材よりも十分量多い発色剤溶液に基材を３時間浸漬し、その基材が吸液できる最大量の吸液量を吸液させ、その後、浸漬している液から最大量吸液した基材を濾別することで取り出し、吸液後の基材重量であるＸ重量部を求める。この吸液後の基材重量Ｘ重量部から、吸液前の基材１００重量部を差し引き、吸液前の基材重量１００重量部で割った比を、重量％表記で表す。すなわち、吸液量（重量％）＝［（吸液後の基材重量Ｘ重量部−吸液前の基材重量１００重量部）／吸液前の基材重量１００重量部］×１００の式より求めることができる。また、基材の種類によって吸液する液量が非常に大きいためバラつきが生じやすい場合は、この試験を３回行った平均値を求めてその基材の吸液量とすることが好ましい。なお、本発明の基材は、このような発色剤溶液量を吸収することができる基材を用いていればよく、実際に、検出材としたときこの量の発色剤溶液量を担持している量を示すものではない。 Specifically, the amount of the color former solution to be absorbed can be determined by the following method. First, assuming that the weight of the dried base material before measurement is 100 parts by weight, the base material can be immersed in a sufficiently large amount of the color former solution for 3 hours to absorb the base material. The maximum amount of liquid absorption is absorbed, and then the substrate that has absorbed the maximum amount from the immersed liquid is removed by filtration, and X parts by weight that is the weight of the substrate after liquid absorption is obtained. The ratio obtained by subtracting 100 parts by weight of the base material before liquid absorption from the weight X of the base material after liquid absorption and dividing by 100 parts by weight of the base material before liquid absorption is expressed in terms of wt%. That is, the amount of liquid absorption (% by weight) = [(base material weight after liquid absorption X parts by weight-base material weight before liquid absorption 100 parts by weight) / base material weight before liquid absorption 100 parts by weight] × 100 It can be obtained more. In addition, when the amount of liquid to be absorbed is very large depending on the type of the base material, when variation is likely to occur, it is preferable to obtain an average value obtained by performing this test three times to obtain the liquid absorption amount of the base material. Note that the base material of the present invention only needs to use a base material that can absorb the amount of the color former solution. Actually, when the detection material is used, this amount of the color former solution amount is supported. It does not indicate the amount.
基材が吸収する発色剤溶液量（吸液量）は、前記基材の重量に対して１５０重量％以上であり、好ましくは２００重量％以上、より好ましくは、３５０重量％以上である。吸液量がより大きい方が、発色剤溶液および試験対象中の水分を吸収しやすく安定した測定結果を得やすい。また、１００，０００重量％以下好ましくは８０，０００重量％以下、より好ましくは６５，０００重量％以下である。吸液量の上限は、基材の種類によるためほぼ制限はないが、一方でこれらの値以上である必要性は低く、また、吸液量が大きすぎる場合、発色剤溶液と試験対象液との液量のバランスが崩れ、正しい試験結果を得られない場合がある。 The amount of the color former solution (absorbed amount) absorbed by the substrate is 150% by weight or more, preferably 200% by weight or more, more preferably 350% by weight or more with respect to the weight of the substrate. The larger the liquid absorption amount, the easier it is to absorb the water in the color former solution and the test object, and it is easier to obtain a stable measurement result. Moreover, it is 100,000 weight% or less, Preferably it is 80,000 weight% or less, More preferably, it is 65,000 weight% or less. The upper limit of the liquid absorption amount is almost not limited because it depends on the type of the substrate, but on the other hand, it is not necessary to exceed these values, and if the liquid absorption amount is too large, the color former solution and the test object liquid The balance of the amount of liquid may be lost and correct test results may not be obtained.
また、本発明における吸液量は、単に純水の吸収量ではなく、使用する発色剤溶液の量として、前記した範囲の量を吸収する基材である。単に水を吸収することができる基材であっても、実際に使用する発色剤溶液は、水と発色剤の他に、ｐＨ緩衝剤や、反応阻害物質抑制剤等、様々な反応、呈色補助剤を加えることが多く、これらはイオンや界面活性剤等、基材として使用される物質が吸収する液量に対して大きな影響を与えることが多いものであるから、水の吸収量とは異なる挙動を示す場合があるためである。 Further, the liquid absorption amount in the present invention is not a pure water absorption amount but a base material that absorbs an amount in the above range as the amount of the color former solution to be used. Even if it is a substrate that can simply absorb water, the color former solution that is actually used is not only water and the color former, but also various reactions and colors such as pH buffering agents and reaction inhibitor inhibitors. Adjuvants are often added, and these often have a large effect on the amount of liquid absorbed by substances used as substrates, such as ions and surfactants. This is because different behavior may be exhibited.
［担持量］
本発明の検出材は、前述したような吸液性を有する基材に、発色剤溶液を担持させたものである。この担持は、具体的な方法として後述するような含浸法などにより行うことができる。ここで、基材に担持させる発色剤溶液量は、その検出材が検出対象とする環境汚染物質等の濃度によって発色することを確認することができる量であればよい。このときの発色剤溶液の担持量は、この検出材を製造する際の仕込み量としての濃度比から求められる値として管理することもできる。この値は、担持された発色剤溶液中の発色剤重量／吸液前の基材重量として、一般的に単位は（ｍｇ／ｇ）で表示される。
[Loading amount]
The detection material of the present invention is obtained by supporting a color former solution on a substrate having liquid absorbency as described above. This supporting can be performed by an impregnation method as described later as a specific method. Here, the amount of the color former solution carried on the substrate may be an amount that can confirm that the detection material develops color depending on the concentration of the environmental pollutant to be detected. The amount of the color former solution supported at this time can also be managed as a value obtained from the concentration ratio as the amount charged when the detection material is manufactured. This value is generally expressed in (mg / g) as the weight of the color former in the supported color former solution / base weight before liquid absorption.
この好ましい担持量の具体例を例示すると、フッ素検出に用いられるランタン−アリザリンコンプレキソンの場合、０．３３〜０．５ｇ／ｇ程度、ホウ素検出に用いられる８−ヒドロキシ−１−（サリチリデンアミノ）−３，６−ナフタレンジスルホン酸の場合、１０〜５０ｍｇ／ｇ程度、鉛検出に用いられるＰＡＲの場合、０．００７５〜７．５ｍｇ／ｇ程度とすることができる。各発色剤や、測定対象中の汚染物質の濃度に応じて、これらは適宜変更されるが、本発明の検出材は、基材に担持させる発色剤液量を変更することでこれらを簡易に調製することができる点でも優れている。 As a specific example of this preferred loading, in the case of lanthanum-alizarin complexone used for fluorine detection, about 0.33-0.5 g / g, 8-hydroxy-1- (salicylidene) used for boron detection In the case of amino) -3,6-naphthalenedisulfonic acid, it can be about 10-50 mg / g, and in the case of PAR used for lead detection, it can be about 0.0075-7.5 mg / g. These are appropriately changed according to the concentration of each color former and the contaminant in the measurement object. However, the detection material of the present invention can be easily changed by changing the amount of the color former carried on the substrate. It is also excellent in that it can be prepared.
この担持量が少ない場合、発色が弱く目視等での確認が困難となる場合がある。一方、過度に高濃度の発色剤を担持させることは、基材を用いる利点を失うものとなるばかりではなく、想定している仕込みの担持量と実際の担持量とが乖離する原因となり、評価を適切に行えなくなったり、発色が強すぎその発色の程度を確認しにくくなったり、他の反応による呈色による弊害が生じる場合がある。また、当該検出材の吸液量の限度に近い発色剤溶液を担持させると、土壌や水から吸液することができなくなり、十分に反応させることができない場合もある。 When the amount is small, the color development is weak and it may be difficult to confirm with the naked eye. On the other hand, loading an excessively high concentration of color former not only loses the advantage of using the base material, but also causes a difference between the assumed loading amount and the actual loading amount. May not be properly performed, color development is too strong, and it is difficult to confirm the degree of color development, and adverse effects due to coloration due to other reactions may occur. In addition, if a color former solution close to the limit of the liquid absorption amount of the detection material is supported, the liquid cannot be absorbed from soil or water and may not be sufficiently reacted.
［基材］
本発明に用いられる基材は、前述したような吸液性を有するものであれば、無機系、有機系問わず用いることができる。このような発色剤吸液量を有する好ましい基材としては、例えば、吸水性ポリマーやホワイトカーボン等があげられる。この吸液性ポリマーおよび／またはホワイトカーボンを基材とすることで、観察性、取り扱い性、生産性に優れた本発明の検出剤を得ることができる。
[Base material]
The base material used in the present invention can be used regardless of whether it is inorganic or organic, as long as it has liquid absorbency as described above.

For example, lanthanum-alizarin complexone that reacts with a fluorine compound has the following reactivity and characteristics. That is, in the presence of fluoride ion of a fluorine compound, a complex (lanthanum) of lanthanum (III) and alizarin complexone (1,2-dihydroxyanthraquinone-3-ylmethylamine-N, N-diacetic acid dihydrate) -Alizarin complexone) is added and this reacts with fluoride ions to form a blue complex complex.

That is, a substrate in which the amount of the color former solution absorbed by the substrate is 150% by weight or more and 100,000% by weight or less with respect to the weight of the substrate is immersed in the color former solution containing the color former. The present invention relates to a method for producing a detection material for evaluating the presence or absence of environmental pollutants. This method can produce the detection material of the present invention with excellent workability. In this immersion, it is preferable to immerse in a color former solution of about 3 to 10 times that of the base material, and a solution that is not absorbed can be obtained by filtration as a detection material.

[Evaluation method]
The present invention can be a method for evaluating the presence or absence of environmental contamination using the detection material of the present invention described above. That is, it can also be achieved as an evaluation method for evaluating the presence or absence of contaminants in the soil or water, or the concentration thereof.
例えば、土壌を評価する方法の場合は、発色剤溶液を担持させた高い吸液性を有する基材による本発明の検出材を用いることで、必要に応じて適宜土壌を水で湿潤させる等した状態に、検出材を直接接触させることで土壌中に、検出材の発色剤が反応して発色する対象となる汚染物質が存在するか否かを評価することができる。また、評価対象が水中の環境汚染物質の場合、その試験対象とする水に、本発明の検出材を直接接触させ、呈色反応の有無から環境汚染物質の有無を評価することができる。 For example, in the case of a method for evaluating soil, by using the detection material of the present invention based on a substrate having a high liquid absorbency carrying a color former solution, the soil was appropriately wetted with water as necessary. By directly contacting the detection material to the state, it is possible to evaluate whether or not there is a pollutant to be colored by the reaction of the coloring agent of the detection material in the soil. Moreover, when the evaluation target is an environmental pollutant in water, the detection material of the present invention can be directly brought into contact with the water to be tested, and the presence or absence of the environmental pollutant can be evaluated from the presence or absence of a color reaction.
この評価方法は、前述のように検出材を土壌に直接接触させることで行って用いてもよい。また、直接接触させず、ろ紙等の吸水性物質を介在させて行うこともでき、ろ紙等を用いる場合、測定後の検出材の回収が容易であり、また、ろ紙を介することで土壌中の水分が検出材に直接吸い上げられ、着色の有無を観察しやすくすることができる。 As described above, this evaluation method may be performed by bringing the detection material into direct contact with the soil. In addition, it can be carried out by interposing a water-absorbing substance such as filter paper without direct contact. When filter paper or the like is used, it is easy to recover the detection material after measurement, and through the filter paper, Moisture is directly sucked up by the detection material, and the presence or absence of coloring can be easily observed.
