摘要: 以新型复配农药助剂——松脂基表面活性剂1号和2号以及传统农药助剂壬基酚聚氧乙烯醚、松香酸聚乙二醇酯和直链十二醇聚氧乙烯醚为目标物,通过实验考察了不同类型农药助剂的初级生物降解特性。8 d的生物降解实验结果表明,松脂基表面活性剂1号的初级生物降解度为79.1%,松脂基表面活性剂2号的初级生物降解度为82.4%,松香酸聚乙二醇酯的初级生物降解度为84.2%,壬基酚聚氧乙烯醚的初级生物降解度为91.1%,直链十二醇聚氧乙烯醚的初级生物降解度大于99%。新型复配农药助剂的组成结构更为复杂,其初级生物降解度要低于直链醇类、酚类的聚氧乙烯醚及单一结构酸类的聚乙二醇酯等农药助剂。

Abstract: Primary biodegradability of the new blend pesticide adjuvants,rosin-based surfactant adjuvants No.1 and No.2,as well as that of the conventional pesticide adjuvants,including polyoxyethylene nonylphenol ether,rosin acid polyethylene glycol ester,and polyoxyethylene lauryl alcohol ether was investigated in laboratory tests of 8 d.The results indicated that primary biodegradability of rosin-based surfactant adjuvants No.1 is 79.1%,that of No.2 is 82.4%,that of rosin acid polyethylene glycol ester is 84.2%,that of polyoxyethylene nonylphenol ether is 91.1%,and that of polyoxyethylene lauryl alcohol ether is higher than 99%.It is obvious that the chemical structure of the new blend pesticide adjuvants is more complex and with lower primary biodegradability as comparing with that of the conventional pesticide adjuvants.

Key words: surfactant, pesticide adjuvants, primary biodegradability
