摘　　要：以黄河包头段上游清洁河段的沉积物为吸附剂,以苯酚、苯胺和氯苯3组分体系为吸附质溶液,开展了多组分体系中芳烃类有机物的吸附特征及相关影响因素的研究。结果表明,苯酚、苯胺和氯苯在该段沉积物上的吸附过程均属非线性的,吸附等温线受吸附剂浓度影响,相互间存在吸附竞争。表层沉积物对苯酚、苯胺和氯苯的吸附量受pH值、溶液离子强度、沉积物中有机质含量等因素的影响。Baotou Channel of the Yellow River has been heavily polluted by industrial discharges and aromatic compounds pollutants are found in the water body. In present paper, adsorption of aromatic compounds on sediments sampled from upward reaches of Baotou Channel the Yellow River was studied. The factors that may affect the adsorption of three aromatic compounds in multicomponent system, i. e. , phenol, aniline and chlorobenzene, were also investigated. The results show that the isotherms of phenol, aniline or chlorobenzene are all nonlinear and adsorption isotherms are dependent on the concentration of adsorbents. The absorption amounts of aromatic compounds by surface sediments are influenced by pH, ionic strength and content of organic matter in sediments.
