二氯辛基异噻唑啉酮灭藻杀菌性能研究

工业循环冷却水系统藻类及细菌等微生物污染会大大影响系统的工作效率.作者考察了新型灭藻杀菌剂二氯辛基异噻唑啉酮对藻类和异养菌的杀灭性能.实验表明:二氯辛基异噻唑啉酮具有良好的灭藻杀菌性能,藻类在活性组分质量浓度1.0 mg/L下曝露96 h,杀灭率大于90%,异养菌在活性组分质量浓度0.5 mg/L下曝露24 h,杀灭率大于99%.

Study on the algaecidal and bactericidal capacity by DCOIT

Algous and bacterial contamination in industrial circulating cooling water has great influence on the working efficency of the system.The algaecidal and bactericidal capacity by 4,5-dichloro-2-n-octyl-3(2H)-isothiazolone(DCOIT),a novel biocide,is discussed.The results show that DCOIT has such performance.Treated with 1.0 mg/L active ingredient for 96 h,the algaecidal ratio is over 90%,and 0.5 mg/L active ingredient for 24 h,the bactericidal ratio is over 99%.
