竹炭吸附去除水中有机污染物的研究进展

摘要

竹炭是一种多孔、比表面积大的新型固体吸附剂，因其制备工艺简单、价格低廉、吸附性能好，因此具有良好的应用前景。本文介绍了竹炭的制备方法、基本性质及吸附动力学特性，着重讨论了竹炭颗粒粒径、用量、被吸附物起始浓度、溶液pH、作用时间、碳化温度等各种因素对竹炭吸附的影响，并阐述了竹炭作为固体吸附剂在去除水中有机污染物方面的应用。%Bamboo charcoal is a new type of solid absorbent due to its porous structure and large specific surface area.As bamboo charcoal is easy to obtain , cheap and absorptive strongly , this kind of material has great future in application.The preparation , characteristics and absorption kinetic performances of bamboo charcoals were introduced , factors affecting bamboo charcoal absorption , such as charcoal particle size , bamboo charcoal amount , starting concentration of the adsorbate , solution pH, time and carbonization temperature , were highlighted.The applications of bamboo charcoals in removal organic pollutants in water were also reviewed.
