膜吸附技术去除水中重金属离子

Removal of Heavy Metals by Membrane Adsorption Techniques

随着工业发展,大量的重金属通过废渣等方式被排入到环境中,给人体健康带来严重威胁。吸附功能膜具有膜过滤和膜吸附双重功能,能有效地去除水中污染物,如重金属离子等。在本文中,阐述了膜吸附剂去除重金属离子的最新相关进展,高吸附容量和优异的重复使用性能使吸附功能膜和杂化膜吸附剂对重金属离子有良好的去除效率。

With the development of industry,a large amount of heavy metals were discharged into the environment through waste residues and other methods,posing a serious threat to human health.Membranes for membrane adsorption have the dual function of membrane filtration and adsorption to be very effective to remove pollutants such as cationic heavy metals.In this review article,recent progresses in the development of membrane adsorption are surveyed,including modified membranes and hybrid membranes.The high adsorption capacity and excellent reusability make the adsorption functional membrane and hybrid membrane adsorbent have good removal efficiency for heavy metal ions.
