摘要
研究了沉积物吸附对硝基苯酚的作用机理及影响因素．结果表明,对硝基苯酚在沉积物上的吸附由其中的有机质含量和结构决定,体系的ｐＨ值对对硝基苯酚的吸附有较大的影响,其主要原因是体系的ｐＨ值控制着沉积物中有机质的溶出量．在实验浓度范围内,分配作用在沉积物吸附对硝基苯酚中占主导地位．
The influence of sorption time,pH,organic matter content and organic matter ingredients onsorption of p-nitrophenol to sediment are researched.The results indicate that the sorpion of p-ni-trophenol to sediments depend on their organic matter.The sorption vary with pH because theaquatic organic matter content dissolved from sediments vary with pH.In all experiments,theisotherms of p-nitrophenol are linear,which suggest that the sorption be dominated by partition.
