摘　　要：该研究以铁酸铜来负载活性炭,并在其表面实施聚多巴胺的修饰,合成出一种名为CuFe_(2)O_(4)@PDA-AC的新型复合材料。该文考察复合材料对环境污染物日落黄(SY)的吸附效果,复合材料对日落黄的最大吸附量达到266.08 mg/g(303 K,pH 3),酸性环境下有利于复合材料对日落黄的吸附。吸附机理研究发现,吸附过程更符合Langmuir吸附等温模型和伪二级动力学模型,升温有利于吸附。In this study,a novel composite material named CuFe_(2)O_(4)@PDA-AC was synthesized by loading activated carbon with copper ferrite and modifying its surface with polydopamine.The adsorption effect of composite material on environmental pollutant sunset yellow(SY)was investigated.The maximum adsorption capacity of composite material on sunset yellow reached 266.08 mg/g(303 K,pH 3),and the acid environment was conducive to the adsorption.The adsorption mechanism found that the adsorption of sunset yellow by composite was more consistent with Langmuir adsorption model and pseudo-second order kinetic model.Heating is conducive to adsorption.
