茶废弃物对溶液中重金属的生物吸附研究进展

茶废弃物是农业固体废弃物的一个重要组成部分，来源广泛，数量庞大.由于其具有吸附特性，利用茶废弃物作吸附剂去除废水中的重金属受到了国内外学者的广泛关注.本文从影响因素、吸附机理、吸附剂制备和脱附再生等方面综述了茶废弃物吸附去除溶液中重金属的最新研究进展，认为吸附机理、制备、脱附再生、工艺参数和后处理等是今后实现茶废弃物吸附剂工业化应用的主要研究方向.

Biosorption of heavy metals from solution by tea waste:A review

Tea waste is an important part of agricultural solid wastes, because of its various sources and huge amount. The heavy metals removal from waste water by tea waste has been paid much attention by the researchers around the world, owing to the adsorption characteristic of tea waste. In this paper, the research advances in the heavy metals removal from aqueous phase by tea waste were summarized from the aspects of affecting factors, adsorption mechanism, pretreatment, desorption, and regeneration,  and the prospects were put forward. It was considered that for the industrialized utilization of tea waste absorbents, further researches should be focused on their adsorption mechanism, pretreatment, desorption and regeneration, technological parameters, and aftertreatment.
