摘　　要：生物炭作为一种新型的吸附剂,近年来成为环境、能源等领域的关注热点。生物炭对水及土壤中的重金属离子如Cu(Ⅱ)、Pb(Ⅱ)等具有较好的吸附去除效果。通过对目前国内外生物炭对重金属离子去除研究的论文进行总结分析,归纳得出了生物炭对重金属的去除机理及其影响吸附效果的因素等。并将生物炭与目前常用的活性炭进行比较,分析了二者的相似性与不同点,指出使用生物炭来代替活性炭去除溶液中的重金属污染是可行的。Biochar, as a new kind of adsorbent, has received more and more attention from environment, energy and many other helds in recent years. Biochar has well capacity to absorb heavy metal ions such as Cu（II） ,Pb（II） in aqueous solution or soil. This paper summarizes the adsorption mechanism and the factors which influence the adsorption effectiveness of biochar after reviewing a large number of papers at home and abroad. The similarities and differences of the adsorption properties between biochar and activated car- bon are made out. The conclusion shows that it is feasible to use the biochar as alternative of activated carbon to remove heavy metals from waste water.
