摘要
随着铅在工业生产中的广泛应用,铅污染废水的处理引起人们的广泛关注。吸附法是一种去除铅离子安全可靠、操作简单、成本低廉的方法。论文综述了在去除铅离子方面应用较广的四类吸附剂(碳材料,矿物材料,新型材料,生物材料)以及它们最新的改性处理,比较了改性后吸附剂的吸附模型和吸附机理并论述了四类吸附剂的优缺点,提出了今后吸附法去除废水中Pb(Ⅱ)的研究重点,为今后废水中Pb(Ⅱ)的去除提供研究思路。
With the wide application of lead in industrial production,the treatment of lead polluted wastewater has attracted widespread attention.The adsorption is a safe,reliable,simple and low-cost method to remove lead ions.Four kinds of adsorbents(carbon materials,mineral materials,new materials and biological materials) which are widely used in lead ion removal and their latest modification treatments are reviewed in this paper.Moreover,the adsorption model and mechanism of the modified adsorbents were compared while their advantages and disadvantages were discussed.The research emphases of Pb(Ⅱ) removal from wastewater by adsorption method in the future were put forward to provide research ideas for Pb(Ⅱ) removal from wastewater.
