Biosorption on lignocellulosic wastes and by-products has been identified as a proper alternative to the existing technologies applied for toxic metal ion and dye removal from wastewater streams. This paper deals with utilization of typical low cost wastes and by-products produced in different food agricultural and agro-industries as biosorbent and reviews the current state of studies on a wide variety of cheap biosorbents in natural and modified forms. The efficiency of each biosorbent has been also discussed with respect to the operating conditions (e.g. temperature, hydraulic residence time, initial metal concentration, biosorbent particle size and its dosage), chemical modification on sorption capacity and preparation methods, as well as thermodynamics and kinetics.
生物吸附在木质纤维素废物和副产品上已被确定为替代现有技术的合适方法,这些技术用于从废水中去除有毒金属离子和染料。本文利用不同食品农业和农业产业中产生的典型低成本废物和副产品作为生物吸附剂,并综述了天然和改性形式的各种廉价生物吸附剂的研究现状。还根据操作条件(例如温度、水力停留时间、初始金属浓度、生物吸附剂粒径及其用量)、对吸附能力的化学改性以及制备方法,以及热力学和动力学,讨论了每种生物吸附剂的效率。
