摘要
农业废弃物主要由纤维素和木质素组成,是一种潜在的重金属吸附剂。文中归纳了几种农业废弃物吸附剂及其改性方法,阐述了改性农业废弃物吸附重金属的机理,讨论了pH、重金属离子初始浓度、吸附剂用量、反应温度等因素对改性农业废弃物吸附能力的影响,并展望了改性农业废弃物的应用前景。
Agricultural waste materials as a potential heavy metal ion adsorbent are usually composed of cellulose and lignin as the main constituents. This paper reviews several agricultural waste materials and its modified forms as adsorbents for the removal of heavy metals from aqueous solutions. The adsorption mechanisms and the influences, such as pH, initial heavy metal ions concentrations, adsorbent dosage and reaction temperature, on the adsorption of modified agricultural wastes were discussed as well. What＇s more, applying prospect of modified agricultural waste materials in waste water treat- ment is also presented.
