中文摘要：本文采用HPLC-UV检测系统测定土壤中磺隆和苯磺隆残留量，在土壤中分别加入了26和15 g.a.i./ha的磺隆和苯磺隆除草剂，并在0 (2 h), 1, 2, 4, 10, 20, 40, 60, 90和120天后随机取样，提取后进行高效液相色谱分析。结果显示，两种除草剂在粉质壤土中的降解速度快于砂质壤土，磺隆和苯磺隆除草剂半衰期分别为5.37-10.82天和3.23-5.72天。两种除草剂在施用120天后并没有扁豆毒性效应。总之，高效液相色谱分析法适用于测定土壤中除草剂残留。
外文摘要：A HPLC-UV detection system was used for determination of sulfosulfuron and tribenuron methyl residues from soils. The soils were fortified with sulfosulfuron and tribenuron methyl at rates of 26 and 15 g a.i. ha(-1) respectively and samples were taken randomly on 0 (2 h), 1, 2, 4, 10, 20, 40, 60, 90 and 120 days after treatment. The final extracts were prepared for analysis by HPLC. The results showed that degradation of both herbicides in the silty loam soil was faster than sandy loam soil. Half-life of sulfosulfuron was ranged from 5.37 to 10.82 days however this value for tribenuron methyl was ranged from 3.23 to 5.72 days on different soils. The residue of both herbicides at 120 days after application in wheat field had no toxicitic effect on lentil. It was concluded that HPLC analysis procedure was an appropriate method for determination of these herbicides from soils.
