| 摘 要： | 采用逐级分离法将大连近海海底沉积物进行分级处理，每级相继去除碳酸盐、有机质和金属水合氧化物，最后一级为粘土矿物。每级沉积物的电子显微镜形态观察结果与逐级分离的预期结果基本吻合。硝基苯在各级沉积物上的吸附行为符合Ｆｒｅｕｎｄｌｉｃｈ等温式，同时证明本文所用的逐级分离法对大连近海海底沉积物的分离有较好的适用性。

| Abstract: | The submarine sediment in the coast of Dalian was divided into four fractions by the sequential separation method. The carbonate, organic matter and hydrous metallic oxides(iron, manganese and aluminium) were removed from the submarine sediment one by one. The lastest grade was the clay mineral. The observation results of the shape of each grade sediment using the electron microscope is basically identical with expected one by the sequential separation method. The adsorption of nitrobenzene on the graded sediments is fit for the Freundlich model. Simultaneously, it is proved that the sequential separation method is well suitable for the separation of the submarine sediment in the coast of Dalian. |
