摘　　要：[目的]了解新型醇醚磷酸酯助剂在环境中的残留降解性。[方法]采用硫氰酸钴法和液相色谱法分别检测施用新型助剂和传统助剂配制农药后的生姜及其土壤中乙氧基型表面活性剂和壬基酚的残留量。[结果]施用新型助剂配制农药后的生姜样品中乙氧基型表面活性剂的残留量分别为266.323、203.541、175.917 mg/kg,土壤样品的残留量分别为109.551、109.551、87.079 mg/kg,均低于施用传统助剂配制农药后的生姜和土壤样品;施用新型助剂配制农药后土壤和生姜样品中均未检出壬基酚。[结论]新型醇醚磷酸酯型助剂的降解性能及其对环境的安全性均优于传统助剂。[Aims] The aim of this paper was to study the degradation of novel alcohol ether phosphate adjuvant in environment. [Methods] The novel and conventional pesticide adjuvants were used in pesticides, and then the surfactant and nonylphenol residues in soil and ginger were detected by CTAS and HPLC, respectively. [Results] When alcohol ether phosphate adjuvant was used, the nonylphenol residues in soil and ginger were not detected, the surfactant residues in soil and ginger were 175.917-266.323 mg/kg and 87.079-109.551 mg/kg, respectively. As conventional pesticide adjuvants were used, the surfactant residues in soil and ginger were higher than which used alcohol ether phosphate adjuvant. [Conclusions] Compared to conventional pesticide adjuvants, the novel alcohol ether phosphate adjuvant has a better degradation performance and environmental safety.
