处理少量饮用水时(如军用水壶),常使用含氯的饮水消毒片,即相当于我国的清水片,其中有效的杀菌成份是氯胺。每片含有效氯为3毫克,在保存过程中,有效氯含量亦能遭受损失,故在使用前对可疑的饮水消毒片亦应进行其中有效氯含量的测定,其法如下:加100毫升蒸馏水或洁净经煮沸过滤的水於玻杯中(白底洋瓷碗亦可),丢入需测定的消毒片,用玻棒捣碎,使充分溶解,搅匀(最好事先将消毒片在乾燥的烧杯中捣碎),然后加2-3满茶匙硫酸氢钠、碘化钾晶体20-30片,1%澱
When dealing with a small amount of drinking water (such as military kettles), often using chlorine drinking water disinfection tablets, which is equivalent to our water tablets, of which the effective bactericidal ingredients is chloramine. Each containing 3 mg of available chlorine, the preservation process, the effective chlorine content can also suffer losses, so the suspect before drinking water disinfection tablets should also be one of the available chlorine content determination, the method is as follows: Add 100 ml of distilled water Or clean the boiled and filtered water in the glass (white porcelain bowl can be), thrown into the determination of the disinfection tablets, mashed with glass rods, to fully dissolve, stir well (the best prior disinfection tablets in the dry Beakers in the mashed), then add 2-3 full teaspoon sodium bisulfate, potassium iodide crystals 20-30 tablets, 1% of the lake
