AI Technical Summary
Technical Problem
Organophosphorus pesticides are highly volatile, which can easily harm sprayers and leave significant residues in agricultural products, thus limiting their use.
Method used
By mixing cationic and anionic surfactants to form a stable vesicle solution, organophosphorus pesticides are encapsulated into an oil-in-water microemulsion using ultrasonic oscillation, and Tween-60 is added for further emulsification to form a highly stable microemulsion.
Benefits of technology
It significantly reduces the volatility and residues of organophosphorus pesticides, improves pesticide safety and application scope, and reduces harm to people and the environment.

Abstract
囊泡封装有机磷农药微乳液的制备方法及其应用，本发明是要解决有机磷农药具有较大的挥发性，易对喷洒的人员产生较大危害、对农产品残留较大等问题。制备方法：一、将阳离子表面活性剂和阴离子表面活性剂分别配制成活性剂溶液，将两种活性剂溶液混合，得到囊泡溶液；二、将有机磷农药溶于有机溶剂中，得到有机磷丙酮溶液，在超声状态下，将有机磷丙酮溶液加入到囊泡溶液中，超声震荡处理，得到水包油型微乳液；三、将Tween‑60加入到水包油型微乳液中，超声震荡处理，然后在室温下陈化处理。本发明采用阴阳离子表面活性剂配伍形成特定囊泡相为介质，利用囊泡的界面效应，提高分散液的稳定性，微乳型制剂能减少农药的挥发性。
