团队简介：本研究团队由1位教授，1位副教授和1位讲师组成，所有成员均获得博士学位。本团队成员近年来一直从事重金属离子六价铬的还原去除，首次指出了在厌氧的反应体系中，硫化物的氧化产物单质S对硫化物还原Cr(VI)有极显著的催化加速作用。发现了不同金属离子对有机酸还原六价铬的不同催化作用机理。在有机污染物的降解方面，主要研究过渡金属离子（如Zn(II)和Cu(II)等）活化过硫酸钠或臭氧等氧化降解有机染料和有机合成中间体等。通过系列研究揭示了过渡金属离子的催化机理，明确了活化中间体和有关影响因素，从而为探索降解环境中的持久高毒的有机污染物的新技术提供科学依据。在新型功能材料的研究方面，目前正在研发介孔磁性材料作为砷，铬等高效吸附剂。采用插入、嫁接和合成等方法修饰或改性获得新型功能材料，这种吸附剂不仅具有优越的吸附性能，同时因具有高磁性，能显著提高吸附剂与废水间的分离效果。
