石墨烯复合材料在水处理中的应用研究

摘要

Graphene, a new type of carbon material, has excellent physical and chemical properties due to its large specific surface area.It is usually used as an adsorbent or composite carrier for the treatment of refractory organic wastewater.After modification, the solubility and controllability of the composites can be optimized.Based on the preparation of composite materials, typical wastewater:dye wastewater, phenol wastewater, pesticide wastewater was selected, and from two aspects the adsorption and catalytic degradation, the study briefly introduces the application and effect of graphene composite effect.The results show that the composite materials can effectively improve the degradation efficiency.However, it is still necessary to strengthen the research on the preparation, recycling and application of composite materials.%新型碳材料石墨烯,因其比表面积大,物理、化学特性优异,通常作为吸附剂或复合材料载体,用于难降解有机废水处理.载体石墨烯改性后,可优化复合材料性能,包括溶解性和可控性.基于复合材料制备,选取典型污染物废水,如染料废水、苯酚废水、农药废水,从吸附处理和催化降解两方面展开,简要介绍石墨烯复合材料的应用研究及作用效果,显示出复合材料可有效提高污染物降解效率,回用效果好.此外,石墨烯复合材料在回用及实际应用方面仍有待进一步研究.
