摘要
经检测,碘树脂对25℃、pH 6.5水中的大肠杆菌、金黄色葡萄球菌、白色念珠菌分别作用1.075、1.713、6.307秒钟,灭除率均可达99.9%以上。灭除率随水温、pH 值、作用时间增加而上升;在水的硅藻土浊度变动干0°～20°间时,对灭除率无明显影响。
Iodine resin is an insoluble contact-type disinfectant formed by adsorption of iodine on strong alkaline anion-exchange resin.It is mainly used for disinfection of drinking water. Examination indicated that the iodine resin could remove and kill more than 99.9% of Escherichia coli,Staphylococcus aureus and Candida albicans in 25℃,pH 6.5 water after contact for 1.075 sec,1.713 sec and 6.307 sec respectively. Test for influencing factors indicated that the removing and killing rate of microorganisms in water by iodine resin increased with increasing water temperature,pH val- ue or contact time.The siliceous earth turbidity of water within the range of 0°～20° had no obvious influence on removing and killing rate.
