Description
本発明者らは、上記の課題を解決すべく鋭意研究を重ねた結果、塩素系酸化剤とスルファミン酸又はその塩を含有する殺菌殺藻剤組成物のｐＨを１３以上とすることにより、塩素系酸化剤の分解を抑制することができ、さらに、アゾール系化合物を含有させることにより、塩素系酸化剤の分解をより効果的に防止して残留塩素濃度を高く維持するとこが可能となることを見いだし、この知見に基づいて本発明を完成するに至った。
すなわち、本発明は、
（１）塩素系酸化剤、アゾール系化合物及びスルファミン酸若しくはその塩を水系に添加することを特徴とする水系の殺菌殺藻方法、
を提供するものである。
さらに、本発明の好ましい態様として、
（２）少なくともスルファミン酸若しくはその塩及びｐＨ調整剤を含む水溶液をｐＨ１３以上に調製した後に、該水溶液に塩素系酸化剤を添加することを特徴とする殺菌殺藻剤組成物の製造方法、
（３）塩素系酸化剤が、次亜塩素酸又はその塩である上記(１)項記載の水系の殺菌殺藻方法、及び、
（４）アゾール系化合物が、ベンゾトリアゾール又はトリルトリアゾールである上記(１)項記載の水系の殺菌殺藻方法、
を挙げることができる。
As a result of intensive studies to solve the above-mentioned problems, the present inventors have determined that the pH of a bactericidal algicidal composition containing a chlorine-based oxidizing agent and sulfamic acid or a salt thereof is 13 or more, Decomposition of oxidizers can be suppressed. Furthermore, by containing an azole compound, it is possible to more effectively prevent decomposition of chlorinated oxidants and maintain a high residual chlorine concentration. As a result, the present invention has been completed based on this finding.
That is, the present invention
(1) A water-based bactericidal and algicidal method comprising adding a chlorine-based oxidizing agent , an azole compound and sulfamic acid or a salt thereof to the water system ,
Is to provide.
Furthermore, as a preferred embodiment of the present invention,
(2) A method for producing a bactericidal algicidal composition, comprising preparing an aqueous solution containing at least sulfamic acid or a salt thereof and a pH adjuster to pH 13 or higher, and then adding a chlorine-based oxidizing agent to the aqueous solution;
( 3 ) The water-based sterilizing algaecide method according to the above ( 1 ), wherein the chlorinated oxidant is hypochlorous acid or a salt thereof, and
( 4 ) The water-based bactericidal and algicidal method according to the above ( 1 ), wherein the azole compound is benzotriazole or tolyltriazole,
Can be mentioned.
Claims (1)
A water-based bactericidal algae killing method comprising adding a chlorine-based oxidant, an azole compound, and sulfamic acid or a salt thereof to the water system.
