The adsorption of tributylphenol ethylene oxide isomers containing various lengths of ethylene oxide chain and positional isomers of tributylphenol on a riverine sediment was studied by thin-layer chromatography combined with high-performance liquid chromatography. The adsorption capacity of the sediment was compared with that of silica, alumina and diatomaceous earth. It was established that the adsorption capacity of the riverine sediment is similar to that of silica. The adsorption of surfactants on the sediment surface is not selective. Neither the length of the ethylene oxide chain nor the position of the butyl substituents on the phenol ring influence significantly the adsorption.
采用薄层色谱与高效液相色谱联用的方法，研究了含有不同环氧乙烷链长度的三丁基酚环氧乙烷异构体以及三丁基酚的位置异构体在河流沉积物上的吸附情况。将沉积物的吸附容量与硅胶、氧化铝和硅藻土的吸附容量进行了比较。结果表明，河流沉积物的吸附容量与硅胶相似。表面活性剂在沉积物表面的吸附没有选择性。环氧乙烷链的长度和酚环上丁基取代基的位置对吸附均无显著影响。
