Abstract
Description
本発明は、水中、具体的には観賞魚用水槽等の水中において、藻類、アオコ等の発生を抑制し、藻抑制剤内部の藻抑制成分の消失によって剤自体の色調が変化する徐放性藻抑制剤に関するものである。The present invention suppresses the generation of algae, blue sea bream, etc. in water, specifically in aquarium fish tanks, etc., and the sustained release property in which the color tone of the agent itself changes due to the disappearance of the algae inhibitor component inside the algae inhibitor It relates to an algae inhibitor.
観賞魚用水槽等に発生する藻類、アオコ等は水槽の外観を損ねる。したがって、これらの発生を抑制するために、ベンゾチアゾール系、フェニル尿素系等の有機系藻抑制剤あるいは、銀、銅、亜鉛（特許文献１〜５）、ヨウ素等の無機系藻抑制剤を使用することが一般的である。Algae, sea cucumbers, etc. that occur in ornamental fish tanks will damage the appearance of the tank. Therefore, in order to suppress these generations, organic algae inhibitors such as benzothiazoles and phenylureas, or inorganic algae inhibitors such as silver, copper, zinc (Patent Documents 1 to 5) and iodine are used. It is common to do.
これらの有機系藻抑制剤や無機系藻抑制剤は、担体に担持させることなく粉末状や液状等で水槽中に直接投入し短期間藻抑制剤としての防藻効果を得る方法や、何らかの担体に担持させた状態で水槽中に投入し長期間藻抑制剤として防藻効果を得る方法により使用されている。These organic algae inhibitors and inorganic algae inhibitors can be added directly to a water tank in the form of powder or liquid without being supported on a carrier to obtain an algae-proofing effect as an algae inhibitor for a short period of time. It is used by a method for obtaining an alga-proof effect as an algae inhibitor for a long time by putting it in a water tank in a state where it is supported on the algae.
しかしながら、従来の藻抑制剤は藻抑制成分の消失とともに色調が変化するといった外観の変化がなく、藻抑制剤としての防藻効果が消失する時期が目視で容易に判別できないという問題があった。However, conventional algae inhibitors have the problem that there is no change in appearance such that the color tone changes with the disappearance of the algae inhibitor component, and the time when the algae-proofing effect as the algae inhibitor disappears cannot be easily determined visually.
また、防藻目的でヨウ素が液状で使用されることがあるが、ヨウ素の昇華性が高いため水槽へ添加した後の藻抑制剤としての持続性が十分ではなく、防藻効果を持続するためにはその添加頻度が多くなり使用者にとって非常に手間が掛かるという問題があった。In addition, iodine may be used in liquid form for the purpose of preventing algae, but because of the high sublimation properties of iodine, the sustainability as an algae inhibitor after adding to a water tank is not sufficient, and the algae prevention effect is sustained. However, there is a problem in that the frequency of addition is increased and it takes much time for the user.
さらに、液状のヨウ素を添加した直後は一時的に水槽中のヨウ素濃度が高くなり、水草や他の水生生物に悪影響を及ぼすという問題があった。
本発明は上記のような問題を解決するための徐放性藻抑制剤を提供するものである。Furthermore, immediately after liquid iodine is added, the iodine concentration in the aquarium temporarily increases, which has a problem of adversely affecting aquatic plants and other aquatic organisms.
The present invention provides a sustained-release algae inhibitor for solving the above problems.
本発明の徐放性藻抑制剤は、ヨウ素とゲル状物質の混合物を、ヨウ素を徐放できる形状もしくはヨウ素を徐放できる材質の容器内に充填した状態で使用されることを特徴とする。The sustained-release algae inhibitor of the present invention is characterized by being used in a state in which a mixture of iodine and a gel-like substance is filled in a container having a shape capable of sustained release of iodine or a material capable of sustained release of iodine.
（ゲル状物質）
ゲル状物質としては、デンプン、アミロース、アミロペクチン、寒天、アガロース、アガロペクチン、カードラン、グルコマンナン、カラギーナン、ゼラチン、カルボキシメチルセルロース、ジェランガム、ヒドロキシプロピルセルロース、キサンタンガム等の、ミクロ的に観察すると巨大な網目構造をもつ高分子ゲルとその混合物が使用できる。さらに、アルギン酸ナトリウム等の多糖類をマグネシウム、カルシウム等の多価のイオンで架橋して得られたゲルも使用することができる。(Gel substance)
As gel-like substances, starch, amylose, amylopectin, agar, agarose, agaropectin, curdlan, glucomannan, carrageenan, gelatin, carboxymethylcellulose, gellan gum, hydroxypropylcellulose, xanthan gum, etc. Polymer gels with a mixture and mixtures thereof can be used. Furthermore, a gel obtained by crosslinking a polysaccharide such as sodium alginate with polyvalent ions such as magnesium and calcium can also be used.
本発明により見出された徐放性藻抑制剤は、ヨウ素により濃い紫色に着色しており水中に設置した場合、内部のヨウ素が水中へ放出されるとともに次第に濃い紫色から薄い紫色へと外観が変化する。透明もしくは半透明の容器を使用した場合、ヨウ素の放出が終了し外観がゲル状物質の透明白色となることで藻抑制剤としての防藻効果の消失が目視で容易に判別できる。The sustained-release algae inhibitor found by the present invention is colored in deep purple by iodine, and when installed in water, the internal iodine is released into water and the appearance gradually increases from dark purple to light purple. Change. When a transparent or translucent container is used, the disappearance of the anti-algae effect as an algae inhibitor can be easily determined visually by the release of iodine and the appearance becoming a transparent white of the gel substance.
また、本発明により見出された徐放性藻抑制剤は、水中でゲル内部のヨウ素を一定期間少量ずつ連続的に水中へ放出することで防藻効果を長期間維持できるため、藻抑制剤を頻繁に添加する手間を省くことができる。ヨウ素を放出する期間は、ゲルを充填する容器の内容積と開放部の面積を任意に設定しヨウ素の消費速度を変えることで容易にコントロールできる。In addition, the sustained-release algae inhibitor discovered by the present invention can maintain the anti-algae effect for a long period of time by releasing iodine inside the gel into water gradually for a certain period of time in water. It is possible to save the trouble of frequently adding. The period during which iodine is released can be easily controlled by arbitrarily setting the internal volume of the container filled with the gel and the area of the open portion and changing the consumption rate of iodine.
さらに、本発明により見出された徐放性藻抑制剤は、ゲル内部のヨウ素が少量ずつ連続的に水中へ放出されるため、一時的に水中のヨウ素濃度が高くなることはない。Furthermore, since the sustained-release algae inhibitor found by the present invention releases the iodine in the gel continuously into the water little by little, the iodine concentration in the water does not temporarily increase.
本発明を実施例により具体的に説明するが、本発明は以下の実施例に限定されるものではない。EXAMPLES The present invention will be specifically described with reference to examples, but the present invention is not limited to the following examples.
ヨウ化カリウム２．４ｇ、ヨウ素１．６ｇ、粉末寒天５０ｇ、水１Ｌをガラスビーカー内で混合し、９０℃に加温したウォーターバスに浸漬して加熱溶解後、中空のアクリル製パイプ（内径１０ｍｍ、外形１２ｍｍ）内に流し込み、室温まで冷却したものを徐放性藻抑制剤とした。アクリルパイプの長さの差異によるヨウ素の放出期間の変化を観察すべく、その長さを５０ｍｍ，６０ｍｍ，７０ｍｍ，８０ｍｍとした４種類の徐放性藻抑制剤を作製し、１０Ｌの水道水中でヨウ素の徐放効果を目視で観察した。徐放性藻抑制剤はゲル状物質内部にヨウ素が存在すれば濃い紫色に見え、ヨウ素が放出されるとゲル状物質のみの白色に変化する。試験開始日より徐放性藻抑制剤が完全に白色になるまでの期間をヨウ素の放出期間とした。その結果を表１に示した。水道水１０Ｌ中（蓋無し）、常温、エアーバブリング有りの条件にて実施した。2.4 g of potassium iodide, 1.6 g of iodine, 50 g of powdered agar, and 1 L of water were mixed in a glass beaker, immersed in a water bath heated to 90 ° C., dissolved by heating, and then a hollow acrylic pipe (inner diameter 10 mm). , 12 mm) and cooled to room temperature was used as a sustained-release algae inhibitor. In order to observe changes in the iodine release period due to differences in the length of acrylic pipes, four types of sustained-release algae inhibitors with lengths of 50 mm, 60 mm, 70 mm, and 80 mm were prepared. The sustained release effect of iodine was visually observed. The sustained-release algae inhibitor appears dark purple when iodine is present inside the gel substance, and changes to white only when the iodine is released. The period from the test start date until the sustained-release algae inhibitor became completely white was defined as the iodine release period. The results are shown in Table 1. The test was carried out in 10 L of tap water (without a lid) at room temperature and with air bubbling.
以上の結果より、本発明で提供される徐放性藻抑制剤は色調による外観の変化で交換時期を判断することができ、容器の形状を設定することによってヨウ素の徐放期間を自在に調整できることが分かる。From the above results, the sustained-release algae inhibitor provided in the present invention can determine the replacement time based on the change in appearance due to the color tone, and freely adjust the sustained release period of iodine by setting the shape of the container I understand that I can do it.
ヨウ化カリウム２．４ｇ、ヨウ素１．６ｇ、粉末寒天５０ｇ、水１Ｌをガラスビーカー内で混合し、９０℃に加温したウォーターバスに浸漬して加熱溶解後、中空のアクリル製パイプ（内径１０ｍｍ、外形１２ｍｍ、長さ８０ｍｍ）内に流し込み、室温まで冷却したものを徐放性藻抑制剤とした。藻の抑制効果を確認するため、あらかじめ藻類を完全に除去した１０Ｌの淡水水槽中で金魚の飼育を行い水槽ガラス面への藻の発生状況を目視で観察した。その結果を表２に示した。2.4 g of potassium iodide, 1.6 g of iodine, 50 g of powdered agar, and 1 L of water were mixed in a glass beaker, immersed in a water bath heated to 90 ° C., dissolved by heating, and then a hollow acrylic pipe (inner diameter 10 mm). , Outer shape 12 mm, length 80 mm) and cooled to room temperature was used as a sustained-release algae inhibitor. In order to confirm the inhibitory effect of algae, goldfish were bred in a 10 L freshwater aquarium from which algae had been completely removed in advance, and the algae generation state on the aquarium glass surface was visually observed. The results are shown in Table 2.
以上の結果より、本発明で提供される徐放性藻抑制剤は長期間高い藻抑制効果を有していることが分かる。From the above results, it can be seen that the sustained-release algae inhibitor provided in the present invention has a high alga inhibitory effect for a long time.
本発明品は、殺菌剤として観賞魚用水槽等以外にも活魚用の生け簀や活魚搬送車への使用が可能であると考えられる。また、スケールアップすれば屋外の池やプール、その他藻の発生を抑制したい場所で使用することができると考えられる。It is considered that the product of the present invention can be used as a sanitizer for a fish for a live fish or a live fish transport vehicle other than an aquarium for aquarium fish. In addition, if scaled up, it can be used in outdoor ponds, pools, and other places where the generation of algae is desired to be suppressed.
