在野外没有开水供应的情况下,为了防止疾病,保证健康,需要对个人饮水实施消毒。做为一种饮水消毒剂,应该是用量小,效果好,速度快,无毒,无味,价格低廉,性质稳定,使用方便。由于某些卤素化合物具有以上某些特点,因而一直被广泛地采用着。但是,仍然存在不少问题,有的消毒时间过长(净水锭需30分钟)、有的稳定性较差(有机碘片)、有的味道不够好(氯味或碘味)。 In the absence of water supplies in the wild, in order to prevent illness and ensure health, personal drinking water needs to be disinfected. As a drinking water disinfectant, should be small dosage, good effect, fast, non-toxic, tasteless, low price, stable quality, easy to use. Some halogen compounds have been widely used because of their above characteristics. However, there are still many problems, some disinfection time is too long (water ingots need 30 minutes), some less stable (organic iodine tablets), some taste not good enough (chlorine or iodine).
