摘　　要：以芘分子为分子荧光探针测定了疏水缔合有机高分子聚合物HAP对多环芳烃类化合物的富集性能.实验证明,疏水缔合聚合物对芘具有良好的胶束增溶和富集作用,且随着聚合物浓度增大、疏水嵌段结构分布均匀适度,富集能力逐渐增强.絮凝实验证明,疏水缔合聚合物对多环芳烃的富集性能可作为有效的辅助手段,实现对水体中微量有机污染物的去除.In this paper,pyrene as a fluorescence probe was used to determine the enrichment of hydrophobically associating polymers（HAP） to polycyclic aromatic hydrocarbons（PAH）.Experimental results show that HAP could enrich pyrene with its micelles,and the enrichment capacity increased with polymer concentration and hydrophobic block structure.Flocculation experiments show that the enrichment of HAP to polycyclic aromatic hydrocarbons could be used as an effective secondary method to realize the removal of trace organic pollutants in water.
