季胺强碱基载碘树脂(或称三碘树脂、碘化树脂),是一种不溶性的广谱消毒剂。不仅能有效地杀灭革兰氏阳性、阴性杆菌,而且对灭活病毒的RNA、DNA也很有效。为探索制备载碘树脂的适宜介质和有效的饮水消毒方案,1984～1985年对载碘树脂的制备和特征进行了研究,现报告如下。材料与方法 (一)载碘树脂柱的制备 1、载体的选择与准备:选用上海树脂厂产的717型强碱基阴离子交换树脂,经过预处理。将717型强碱基阴离子交换树脂首先进行再甲基化,使一般出厂树脂中含有的20％叔胺转变为季胺,其方法是用0.055M硫酸二甲酯按一定的当量比处理717型阴树脂,然后以95％
Quaternary ammonium base-iodine-containing resin (or triiodide resin, iodinated resin), is an insoluble broad-spectrum disinfectant. Not only can effectively kill Gram-positive, negative bacilli, but also inactivated virus RNA, DNA is also very effective. In order to explore the preparation of iodine-containing resin suitable medium and effective drinking water disinfection programs, 1984 ~ 1985 iodine-containing resin preparation and characteristics were studied, are as follows. Materials and methods (a) Preparation of iodinated resin column 1, carrier selection and preparation: Selection of Shanghai Resin Factory production of 717 strong base anion exchange resin, after pretreatment. The 717 strong base anion exchange resin first re-methylation, the general factory-made resin containing 20% of the tertiary amine into quaternary amine, the method is to use 0.055M dimethyl sulfate at a certain equivalence ratio 717 Yin resin, and then 95%
