Zif-8吸附剂对水中重金属离子的吸附性能研究

摘要

Heavy metal ion pollution has become a hotspot in recent years. The zeolitic imidazolate frameworks belong to a kind of microporous material with tunable apertures and chemical properties and have functional interactions with heavy metals icons,which can play a great role in the treatment of water pollution. The optimal adsorption conditions of the modified adsorbent were explored in different adsorption conditions such as pH level of 5.8 ~7.8, adsorption temperature of 20~45℃ and dosage of adsorbent of 12 g/L. The objective provided theoretical reference for the practical application of ZIFs in the treatment of real waste water.%重金属离子污染成为近年来学者关注的热点.沸石咪唑酯骨架结构材料(ZIFs)是一类具有可调整孔洞大小及化学性质的多孔材料,可作为一种优良的重金属离子的吸附剂,能在水污染治理中发挥较大作用.实验考察Zif-8吸附剂在不同的吸附条件下的使用差别,探究出较好吸附剂使用条件温度在20~45 ℃间,pH为5.8~7.8,投放量为12 g/L.以期为ZIFs材料应用于实际污染水体的处理提供理论支撑.
