结合固相萃取(SPE)-高效液相色谱技术，运用批量平衡法测定不同土壤对克百威的吸附-脱附量，拟合Freundich﹑ Langmuir和DMM双模型方程，分析吸附-脱附量与土壤理化性质相关关系。实验表明，在高浓度时，土壤对克百威的吸附/脱附量与吸附平衡溶液中克百威的浓度呈良好线性关系，而低浓度时，克百威吸附-脱附量波动明显。实验结果拟合Freundich方程效果最佳，检验参数Kf和n值与受试土壤理化性质间呈相关关系。土壤中粘粒﹑有机质含量和阳离子交换量(CEC)对吸附量影响大，而在脱附行为中， CEC﹑砂粒﹑粉粒﹑交换性钙含量均有显著影响。

Combined with solid-phase extraction (SPE)-high performance liquid chromatography using a batch equilibrium method for the determination of different soil carbofuran adsorption-desorption amount fitting Freundich, Langmuir and DMM model equations, analysis of the adsorption-desorption amount soil physical and chemical properties. Experiments show that soil at high concentrations of carbofuran adsorption -desorption and adsorption equilibrium solution concentration of carbofuran was linear, low concentrations of carbofuran adsorption-desorption amount fluctuates significantly. Experimental results fitting Freundich equation effect best test parameters Kf and n values the test soil physical and chemical properties of correlation between the soil clay, organic matter content and CEC on the adsorption amount off attached behavior, CEC, sand, silt, exchangeable calcium content had significant effects.
