本考案は水中のイオンおよび溶存物質を測定し

クロム酸銀を保持させた塩素イオン検知管などが
あり、これらは電源を必要とせず、携帯に便利で
あり、かつ現場での校正を必要としないなどの理
由により広く使用されている。Conventional technology Detection tubes used for process quality control or measurement of harmful substances in wastewater include cyanide ion detection tubes in which o-tolidine and copper sulfate are held in a silica gel carrier, and cyanide ion detection tubes in which lead sulfate is held in a silica gel carrier. Dissolved sulfide detection tubes and chloride ion detection tubes that contain silver chromate in a silica gel carrier are available.These tubes do not require a power source, are convenient to carry, and do not require on-site calibration. Widely used for a reason.
これらの検知管は２種類あつて、被検液１mlま
たは２mlをガラス製注射器などで注入して操作す
る注入法と、被検液に浸漬して毛細管現象を利用
し、充填剤全体が液で満たされた状態を終了点と
する浸漬法とに分かれる。このうちで、浸漬法は
注射器および接続管を使用しないので、操作が容
易なため、一般に多く使用されている。 There are two types of these detection tubes; one is an injection method in which 1 ml or 2 ml of the test liquid is injected with a glass syringe, and the other is a method in which the entire filler is immersed in the test liquid and uses capillary action. It is divided into the immersion method and the immersion method, which ends at a filled state. Among these methods, the immersion method is generally used because it is easy to operate because it does not use a syringe or a connecting tube.
解決しようとする問題点
しかし浸漬法の場合、浸漬させて終了点となつ
た状態で、そのまま被検液に浸漬しておくと上端
開口から液の蒸発が起こるのでさらに被検液が吸
上げられて検知管の変色域が上昇して誤差が大き
くなるなどの問題点があつた。Problems to be Solved However, in the case of the immersion method, if the sample is left immersed in the test liquid at the end of the immersion, the liquid will evaporate from the opening at the top and more test liquid will be sucked up. This resulted in problems such as an increase in the discoloration range of the detector tube and an increase in errors.

との間に、水によつて膨潤することができる材料
を充填してあることを特徴とする水質測定用検知
管によつて解決することができる。Means for Solving The above-mentioned problems of the present invention are as follows:
A detection agent that changes color due to ions in the water to be measured is housed in a space separated by two ventilation/water-permeable fixed plugs, and when used, both ends of the glass tube are cut to make an opening, and one end is opened. Immerse it in the water to be measured,
A detection tube that sucks up water into a detection agent through capillary action and measures the ion concentration in the water based on the length of the discolored detection agent. This problem can be solved by a detection tube for measuring water quality, which is characterized by being filled with a material that can swell with water.
作 用
本考案は、浸漬側とは反対側に、膨潤性材料を
充填してあり、液が検知剤層の上部まで浸透して
膨潤性材料に触れると、この樹脂は液を保持して
体積を著しく増加することにより水の浸透を妨害
して上端開口よりの液の蒸発を防ぐ。Function In this invention, the side opposite to the immersion side is filled with a swellable material, and when the liquid penetrates to the top of the detection agent layer and touches the swellable material, this resin retains the liquid and increases its volume. This significantly increases water penetration and prevents evaporation of liquid from the upper opening.

A paper strand cut into a length of 12 mm was dropped from the top of the glass tube, and then a small amount of absorbent cotton was applied as a fixing stopper 3 with a thin stick so that the upper part of the strand was embedded. Separation material 4 was 60 to 80 mesh silica sand. Detector 5 is prepared by dissolving 0.28g of potassium chromate in 50ml of 50% methanol solution.
Add 100 to 200 meshes of 50 g of silica gel and dry, then add 0.34 g of silver nitrate to the dried gel.
A solution dissolved in 50 ml of 50% methanol solution was added and dried again to prepare a detection agent. The swellable material 6 is a mixture of finely granulated glucose and mannose at a ratio of 2:1, or Sumikagel (trade name, manufactured by Sumitomo Chemical), which is a super absorbent resin of a saponified vinyl acetate-acrylic acid ester copolymer. can be used.
