;1994, 11(1): 80-83.
-
The adsorption and desorption on "Fengqin" green tea from aqueous solution containing Ag-were studied; The adsorption equilibrium constant(b) and maximum adsorption capacity(qm) 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.
