| 摘 要： | 在一定的浓度范围内，对久效磷和甲基对硫磷在黄河沉积物中的吸附特性进行了研究。并观察了pH值和离子强度对吸附的影响。结果表明，久效磷的吸附过程为一级动力学规律；久效磷和甲基对硫磷的吸附可用Freundich等温式和Langmuir等温式较好地描述；久效磷在黄河沉积物中的吸附表现为分配作用和表面吸附共同作用，而甲基对硫磷则以分配作用占主导地位。

| Abstract: | Study on adsorption of monocrotophos and parathion-methyl on the sediment of Yellow River, and observation of effects of pH value and ionic strength on adsorption has been conducted. The result showed that the process of monocrotophos adsorption is the first order kinetic law; and adsorption of monocrotophos and parathion-methyl could be described with Freundlich isotherm and Langmuir isotherm; the adsorption effect of monocrotophos on sediment of Yellow River showed co-effect of surface sorption and distribution, and parathion-methyl mainly showed distribution. |
