木质素衍生物合成吸附材料在污水净化处理中应用

Application of lignin and its derivatives as adsorbent materials for the treatment of industrial wastewater

木质素是地球上极具潜力的可再生资源,在植物体内,木质素的组分约占三分之一,其含量仅次于纤维素。木质素是自然界中特含芳环的三维网状天然高分子聚合物,是合成环境友好型材料的主要生物质资源之一;如何有效利用好这种环保型可再生资源,是当下科研的焦点。主要介绍了木质素及其衍生物所合成的复合材料,作为吸附剂应对于染料废水、重金属废水以及含油废水的处理与净化研究现状,探讨了木质素及其衍生物作为吸附剂未来的发展趋势。

Lignin is a renewable resource with great potential on earth.In plants,Lignin,comprising approximately one-third of the components,has a content second only to cellulose.Lignin is a three-dimensional network natural polymer containing aromatic rings in nature,so it is one of the main biomass resources for the synthesis of environment-friendly materials.How to effectively use this environment-friendly renewable resource has become the focus of current scientific research.This paper mainly introduces the composite materials synthesized by lignin and its derivatives.The research status of the treatment and purification of dye wastewater,heavy metal wastewater and oily wastewater as adsorbent was discussed.The future development trend of lignin and its derivatives as adsorbent was also discussed.
