Abstract: 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.

Key words: tea waste, biosorption, heavy metal, temperature-shifted controlling, endive, temperature sensitive period, bolting and flowering.
