Gemini表面活性剂的杀菌性能

Bactericidal Behaviour of Gemini Surfactant

采用双子表面活性剂16-4-16、十二烷基二甲基苄基氯化铵1227、异噻唑啉酮3种杀菌剂杀灭回注水中的硫酸盐还原菌(SRB)、铁细菌(FB)及腐生菌(TGB)3种细菌,并用绝迹稀释法对杀菌前后菌数进行测定。实验结果表明,杀菌剂双子表面活性剂和杀菌剂1227的杀菌效率均达到企业标准,且杀菌剂双子表面活性剂的杀菌效率达到99%以上,具有良好的耐药性,可将杀菌剂1227与杀菌剂双子表面活性剂交替应用于现场。

Three kinds of bactericidal agents including Gemini suffactant 16 -4 - 16, 1227, and isothiazolinone were in removing sulphate reducing bacteria, ferrobacteria , and saprophytic bacteria which existed in recirculated water, and the vanished dilution method was used to determined the concentration of the bacteria. The results indicated that Gemini surfactant and 1227 had good bactericidal behaviour which could meet the standards of company. Gemini surfactant could kill above 99% bacteria and had good drug fastness. Both of Gemini surfactant and 1227 could be alternatively used in the field .
