摘　　要：以FeCl_(3)、FeCl_(2)、氧化石墨烯(GO)和二磺酸酞菁铜为原料,首先采用化学共沉淀法制备了磁性氧化石墨烯(MGO),再用共混法制备了磁性氧化石墨烯负载酞菁铜(CuPc@MGO),采用红外光谱、XRD、拉曼光谱等手段对其进行结构表征。以CuPc@MGO为去除剂,采用紫外可见吸收光谱法研究反应时间、温度、催化剂用量、初始浓度和溶液pH值对目标污染物2,4-二氯酚(2,4-DCP)去除效果的影响。实验结果表明,在25℃,CuPc@MGO用量为60 mg/L,pH值=6.5时,浓度为40 mg/L的2,4-DCP,在300 min时的去除率最高,为56.3%。Copper phthalocyanine supported on magnetic graphene oxide(CuPc@MGO)was prepared using FeCl_(3),FeCl_(2),graphene oxide(GO)and copper phthalocyanine disulfonate as raw materials.The composites were characterized by IR,XRD and Raman spectra.The removal performance of 2,4-dichlorophenol(2,4-DCP)was carried out using CuPc@MGO as removing agent,and the factors on removal rate of the reaction time,reaction temperature,catalyst dosage and pH value were studied by UV/Vis absorption spectroscopy.The results showed that the removal rate was the highest for 2,4-DCP solution with 40 mg/L when the dosage of CuPc@MGO was 60 mg/L,pH value was 6.5,and the removal rate was 56.3%within 300 min at 25℃.
