为了解氧化电位水消毒剂的性能及消毒效果,用加速法作稳定性试验,用称量法作金属腐蚀性试验,用悬液法作微生物杀灭效果试验。结果表明,在54℃下放置2周,A剂有效浓度下降43.66%。对不锈钢无腐蚀,对碳钢、铝和铜均为中度腐蚀;腐蚀速率R分别为:0.000、0.2374、0.2551和0.2565mm/a。100%杀灭大肠杆菌(8099)、金黄色葡萄球菌(ATCC 6538)、白色念珠菌(ATCC 10231)、枯草杆菌黑色变种芽胞(ATCC9372)的剂量分别为:45mg/L作用10min、64mg/L作用15min、100mg/L作用25mm、250mg/L作用20min。HBsAg的抗原性被破坏所需剂量为240mg/L作用2min。结论:氧化电位水消毒剂稳定性较好,对不锈钢无腐蚀,对碳钢、铝和铜中度腐蚀,对细菌杀灭作用强,对HBsAg破坏作用迅速。
In order to understand the performance and disinfection effect of disinfectant of oxidizing potential water, the stability test was made by accelerated method, the metal corrosion test was carried out by weighing method, and the killing effect test of microorganism was carried out by suspension method. The results showed that at 54 ℃ for 2 weeks, the effective concentration of A decreased by 43.66%. No corrosion of stainless steel, carbon steel, aluminum and copper are moderate corrosion; corrosion rate R were: 0.000,0.2374,0.2551 and 0.2565mm / a. The doses of 100% killed E. coli (8099), Staphylococcus aureus (ATCC 6538), Candida albicans (ATCC 10231) and B. subtilis ATCC 9372 were 45 mg / L for 10 min and 64 mg / L respectively 15min, 100mg / L effect 25mm, 250mg / L effect 20min. HBsAg antigenicity required to destroy the required dose of 240mg / L role 2min. CONCLUSION: Oxidant water disinfectant has good stability, no corrosion to stainless steel, moderate corrosion to carbon steel, aluminum and copper, strong bacteriocidal action and rapid destruction to HBsAg.
