表面活性剂复配及其对百草枯增效试验

Synergism test of surfactants to paraquat

试验了十二烷基苯磺酸、OP - 1 5、AES 3种表面活性剂和其复配后组合物的表面张力及接触角的变化情况 ,通过表面张力法确定其临界胶束浓度CMC ,根据CMC值选择合适的表面活性剂并按一定浓度添加到百草枯药液中 ,对其进行田间除草试验。结果表明 :OP - 1

The report studied the alternative of surface tension and contact angle of dodecylbenzene sulfonic acid, POE(15) octyl phenyl ether, AES and their mixture The results showed that the mixture have higher effect than the single reagent,The CMC was tested by surface tension the best surfactants was adopted and added to paraquat, relative herbicide activity was tested. The result showed that surfactants have synergist activity to paraquat
