摘要
农作物废弃物中含有丰富的纤维素和木质素。纤维素作为自然界中储量最大的天然高分子材料,具有价廉易得、易被微生物降解、不会给环境带来第二次污染等特点,长期以来对其开发利用一直是科技工作者研究的热点,而利用天然吸附材料处理含重金属废水是目前最有前途的方法之一。作者主要从生物吸附的概念和对废水中污染物的吸附机理方面,综述了以纤维素、木质素为主要成分的农作物废弃物作为吸附材料或用来制备絮凝剂的研究情况以及存在的问题,探索了今后的研究方向。
Agricultural waste by-product contains abundant cellulose and lignin.As one of the most abundant renewable natural polymer on earth,cellulose is readily available and inexpensive. Also, it can be biodegraded easily without pollution on environment. Many investigators have worked on the development and utilization of cellulose for a long time. Biosorption is one of the most promising technologies in the treatment of wastewater containing heavy metals. The concept and the mechanism of adsorption, cellulose, lignin adsorption stuff and flocculation are reviewed. The advance agricultural waste by-product of industrial wastewater and the prospect of its application and the problems involved are discussed ,and some suggestions on the research of adsorption material are presented.
