目前,饮用水的消毒仍以氯为主,但氯同水中存在的某些有机物反应生成卤化产物,可能与致癌有关,同时氯臭使人厌恶,因此,国内外学者都致力于寻找安全的消毒剂来替代氯剂消毒饮用水。有机碘较氯为优:结晶碘由于碘量高,有可能造成碘中毒;臭氧是优良的消毒消,但没有持续杀菌作用;三碘树脂具有高度的抗菌能力。三碘树脂是固相不溶性接触消毒剂,不会增加水的化学成分,剂型与消毒方法比其它消毒剂优越,应用于饮用水的终端消毒是理想的介质。本文就合成工艺,消毒效果及其影响因素进行了研究。
At present, the disinfection of drinking water is still dominated by chlorine, but chlorine reacts with some organic substances present in the water to form halogenated products, which may be carcinogenic and chlorine disgusting. Therefore, both domestic and foreign scholars are devoted to finding safe disinfection Agent to replace chlorine disinfection of drinking water. Organic iodine is better than chlorine: crystalline iodine due to high iodine, may cause iodine poisoning; ozone is an excellent consumer disinfection, but no sustained sterilization; triiodide resin has a high antibacterial capacity. Three iodine resin is a solid insoluble contact disinfectant, does not increase the chemical composition of water, dosage forms and disinfection methods superior to other disinfectants, used in drinking water disinfection terminal is the ideal medium. In this paper, the synthesis process, disinfection effect and its influencing factors were studied.
