| 摘 要： | 研究了久效磷在海洋沉积物上的吸附行为，发现其吸附行为主要受沉积物有机质的影响，沉积物有机质的分配作用对久效磷的吸附起主要作用，在实验浓度范围内，吸附行为很好地服从线性吸附等温式，因而其吸附行为较为简单，海水的离子强度对其吸附行为影响很大，海水中分配系数明显高于淡水，温度对其吸附行为也起一定的作用，分配系数随着温度的升高略微减小。

| Abstract: | In the paper,the sorption behavior of monocrotophos on marine sediment was investigated.The sorption behavior of monocrotophos was mainly influenced by the organic carbon contents of se- diments .Partition effect of sediment organic carbon had a major role on the sorption of monocrotophos.Its sorption behavior was fit with linear isotherm very well;therefore its sorption behaviors were preferably simple.Ionic strength(salinity) of seawater strongly influenced the sorption behavior of monocrotophos.Partition coefficients in seawater were obviously much greater than those in fresh water.Temperature has some function on the sorption behavior of monocrotophos.Partition coefficients of isotherms slightly reduced as the temperature increased. |
