摘要
随着矿山开采、金属冶炼加工、化工产业的发展,各种工业废水排放入水环境,致使各类水体污染日趋严重。近年来吸附法作为一种去除水污染物的有效方法,受到了广泛关注。研发新型高效廉价吸附剂则成为该领域的研究热点。生物炭作为一种新型吸附剂,是一种绿色环保的修复材料,具有价格低廉,制备原料来源广泛,孔隙度大、比表面积大、吸附性能强的特点,所以其在重金属吸附与去除的应用中具有良好的潜力与前景。本文针对以生物炭作为水中污染物吸附剂的研究现状进行了总结,对其吸附机理进行了分析。希望本文能为生物炭在我国的水处理技术研究领域的推广与应用提供参考。
As the development of mining industry, metallurgy, chemical industry, large amount of industry waste water has been discharged into water environments, it leads to a serious pollution in surface water. Recently, adsorption method is widely used in waste water treatment technology. Finding efficient and economic absorbent has become a hotspot for the application of this method. As an environmental-friendly material for remediation, biochar has low price, high porosity and specific surface area, absorption ability, wide range of preparation material. It has very large potentials for heavy metal remediation and waste water treatment field. Therefore, studies used biochar as absorbent for heavy metal is collected and summarized. The interaction mechanisms between biochar and heavy meal are discussed.
