为了解有效氯与铜离子的协同杀菌效果,进行了悬液定量杀菌试验。结果,以含铜离子1.0mg/L或有效氯0.1mg/L的消毒液对悬液中大肠杆菌作用4h,平均杀灭率分别为61.90％与93.51％;以含有效氯0.1mg/L与铜离子1.0mg/L的消毒液作用4h,平均杀灭率达99.90％。说明试验浓度的有效氯与铜离子对大肠杆菌有协同杀灭作用。 To understand the synergistic bactericidal effect of available chlorine and copper ions, a suspension quantitative disinfection test was carried out. The results showed that the average killing rates were 61.90% and 93.51%, respectively, for 4 h with the disinfectant solution containing 1.0 mg / L copper or 0.1 mg / L effective chlorine, and the average killing rates were 61.90% and 93.51% Copper ions 1.0mg / L disinfectant role 4h, the average kill rate of 99.90%. The experimental concentration of chlorine and copper ions have synergistic killing effect on E. coli.
