| 摘 要： | 以辛基苯基聚氧乙烯醚(TX-100)和十二烷基苯磺酸钠(SDBS)为表面活性剂,正丁醇为助表面活性剂,制备了水基型氯氰菊酯农药微乳剂,并通过相图、负染-电镜、电导率、分配系数、接触角测定等方法对其结构和性质进行了表征.结果表明:配制的水基型氯氰菊酯微乳体系属于O/W型,其微乳液液滴直径≤100nm,氯氰菊酯在微乳液液滴和水连续相之间的分配系数为2.49×104.

| Abstract: | Water-based cypermethrin microemulsion is prepared from TX-100/(SDBS)/n-butanol/H2O system.The properties and structure of the microemulsion are studied by phase diagram,negative-staining TEM,conductivity,distribution coefficient and contact angle.The obtained results show that the microemulsion is just O/W type.The droplet radium is within 100 nm.The distribution coefficient of cypermethrin between microemulsion droplet and water is about 2.49×104. |
