汞吸附研究进展

Research progress of mercury adsorption

汞是常温常压下唯一以液态存在的金属,由于其高挥发性和剧毒性,排放到环境中容易造成严重的污染。而且,长期暴露在汞含量超标的环境中对人体具有极大的伤害。主要综述了当前应用吸附法治理气体、水体和土壤中汞污染的研究进展,并指出生物吸附技术是今后治理重金属污染的重要发展方向。

Mercury is the only metallic element that is liquid at standard conditions for temperature and pressure , which may easily cause serious pollution because of its extreme volatility and toxicity. Furthermore, great harm would occurred by long-term exposure to the environment which has excessive mercury. Recent research progress by the adsorption treatment of mercury pollution in gas, water and soil was summarized in this review. Among these adsorption methods, biosorption technology would be the important directions for the future control of heavy metal pollution.
