壳聚糖复合材料吸附废水中Cr(VI)、Pb(II)和Cu(II)进展

Research Progress on Adsorption of Cr(VI),Pb(II)and Cu(II)from Wastewater by Chitosan Composites

随着工业的发展,水体污染也变的越来越严重。如何高效的从废水中有效去除重金属仍然是目前研究的一个热点,应用可再生、可生物降解材料处理富含重金属的工业废水,能高效消除废水中的重金属和有机污染物,以获得优质水。本文综述了用生物质基壳聚糖及其复合材料对废水中的Cr(VI)、Pb(II)、Cu(II)等主要的有毒重金属进行处理的进展,同时研究吸附的最佳条件,不同吸附剂对同一重金属的吸附效果,以及在不同水介质中重金属离子的吸附能力。

With the development of industry,water pollution has become increasingly verified.How to effectively remove heavy metals from wastewater is still a hot topic in current research.The application of renewable and biodegradable materials to treat wastewater rich in heavy metals can efficiently eliminate heavy metals and organic pollutants in wastewater,in order to obtain higher quality water resources.The research progress on the treatment of Cr(VI),Pb(II),Cu(II)and other major toxic heavy metal in wastewater by using biomass based chitosan and its composite materials was reviewed.
