敌百虫(O,O-二甲基-2,2,2-三氯-1-羟基乙基磷酸酯)是一种有机磷杀虫剂。它具有对昆虫的毒杀作用强而对高等动物的毒害小的优点。因此,在防治害虫方面应用日广。近来我們发現用敌百虫溶液浸泡过的蚊帐,对蚊虫具有相当持久的触杀作用。为了进一步研究浸泡蚊帐时敌百虫的用量与持久时間和防蚊效果之間的关系,需要一个簡便而又灵敏的定量方法,用以测定帐紗上敌百虫的残留量。根据以往文献的报道,敌百虫的測定方法有如下几种:(1)在一定条件下使敌百虫水解,然后用銀量法测
Trichlorfon (O, O-dimethyl-2,2,2-trichloro-1-hydroxyethyl phosphate) is an organophosphorus insecticide. It has the poisonous effect of insects on the higher animals poisoned the advantages of small. Therefore, in the control of pests wide range of applications. Recently, we found that mosquito nets impregnated with trichlorfon solution have a fairly long lasting effect on mosquitoes. In order to further investigate the relationship between the amount of trichlorfon and the duration and mosquito control effect when immersed in mosquito nets, a simple and sensitive quantitative method is required to determine the residual amount of trichlorfon on the scaffold. According to previous reports, trichlorfon determination of the following methods: (1) under certain conditions to make trichlorfon hydrolysis, and then measured by the amount of silver
