摘　　要：工业外排废水所含的硫氰化物严重影响生态环境和人类健康。目前,常用的降解方法包括生物降解法、Fenton催化氧化法等。其中,Fenton催化氧化法作为一种高级氧化技术,其选用试剂的氧化性能难以充分发挥。因此制备具有高催化活性的催化剂是关键之举。基于氧化石墨烯(GO)的优异性能,微波辅助加热和诱导强化催化的作用,本文成功制备出具有优异催化效果的Fe2+/GO复合催化剂,当Fe2+/GO量为25 mg时,对SCN-去除效果最佳,可达到96.0%。Sulphur cyanide contained in industrial effluent seriously affects the ecological environment and human health.At present,commonly used degradation methods include biodegradation,Fenton catalytic oxidation and so on.Among them,Fenton catalytic oxidation is an advanced oxidation technology,and the oxidation performance of the selected reagents is difficult to be fully exploited.Therefore,the preparation of catalysts with high catalytic activity is a key task.Based on the excellent performance of graphene oxide(GO),microwave-assisted heating and induction-enhanced catalysis,this paper successfully prepared a Fe2+/GO composite catalyst with excellent catalytic effect,and the best effect of 96.0 % for SCN-removal was achieved when the Fe2+/GO amount was 25 mg.
