The adsorption and desorption on "Fengqin" green tea from aqueous solution containing Ag-were studied; The adsorption equilibrium constant(b) and maximum adsorption capacity(q_m) in Langmuir equation and the experimental constants K and 1/n in Freundlich equation were determined. The effects of temperature and pH on the adsorption of Ag-were also examined.A 0.1mol/L Na₂S₂O₃ solution could quantatively desorb Ag.
