| 摘 要： | 采用气相色谱(GC-FPD)法建立了丙溴磷在水和土壤中的残留分析方法。结果表明,丙溴磷在水和土壤中的平均回收率在87.18%~103.64%之间,变异系数为4.84%~9.89%;丙溴磷在水和土壤中的最低检测浓度分别为0.005 mg/L,0.05 mg/kg。采用平衡吸附法和薄层层析法研究了丙溴磷在砂土、壤土和粘土中的吸附和迁移特性。结果表明:丙溴磷在砂土、壤土和粘土中的吸附常数Kd分别为12.70、33.65和74.92,土壤对丙溴磷的吸附能力与土壤有机质含量呈正相关,其移动性分别表现为在砂土、壤土中不易移动,在粘土中不移动。

| Abstract: | An analytical method for determining Profenofos residues in water and soil by GC-FPD was described.Results showed that the minimum detectable concentration in water and soil samples were 0.005 mg/L and 0.05 mg/kg respectively.Average recoveries were 87.18%~103.64%,and coefficient of variation ranged from 4.84%~9.89%.Adsorption and mobility of Profenofos in 3 kinds of soils including sand,loam and clay were studied using batch equilibrium technique and soil thin layer chromatography.Results showed that absor... |
