摘　　要：鉴于氧化石墨烯(GO)比表面积大和吸附性强、高铁酸钾(K_(2)FeO_(4))氧化性强但容易分解的性质,探究了以GO包覆K_(2)FeO_(4)制备复合材料GO@K_(2)FeO_(4),以环丙沙星(CIP)为代表污染物,分析了K_(2)FeO_(4)@GO处理抗生素废水的处理效果。扫描电子显微镜对GO@K_(2)FeO_(4)表征得出:GO能很好地包覆K_(2)FeO_(4)。处理CIP废水的最佳条件为:GO与K_(2)FeO_(4)的混合配比、溶液pH值和GO@K_(2)FeO_(4)的添加量分别为5.0%、5.0和0.3g/L废水。在此优化条件下,CIP的去除率可达到90.1%,比单独使用K_(2)FeO_(4)处理时的去除率提高了19.9%。综合可知:GO@K_(2)FeO_(4)具有更好的稳定性和去除CIP的功能,对抗生素废水的处理具有很好的前景。Due to the large specific surface area and strong adsorption ability of graphene oxide(GO),and the strong oxidation ability but easy decomposition of potassium ferrate(K_(2)FeO_(4)),the GO coated K_(2)FeO_(4)composite GO@K_(2)FeO_(4)was investigated.Ciprofloxacin(CIP)was used as the model substance,and the treatment effect of K_(2)FeO_(4)@GO on CIP wastewater was analyzed.The characterization performance of GO@K_(2)FeO_(4)by scanning electron microscopy showed that GO could coat K_(2)FeO_(4)well.The optimized conditions were obtained as follows:the mixing ratio of GO and K_(2)FeO_(4),solution pH value and addition of GO@K_(2)FeO_(4)were 5%,5 and 0.3 g/L wastewater,respectively.Under the optimized conditions,the removal rate of CIP can reach 90.1%.Compared with K_(2)FeO_(4)treatment alone,the removal rate increased by 19.9%.In conclusion,GO@K_(2)FeO_(4)has better stability and CIP removal function,which has a good prospect for the treatment of antibiotic wastewater.
