【Abstract】 The adsorption isothermal curve of germanium with resin D16 is determined in laboratory. The curve conforms with Freundlich adsorption isothermal equation i e lg θ eq =0 8351g C eq +1 096(in HCl solution)and lg θ eq =0 7861g C eq +1 285(in H 2SO 4 solution) The adsorption heat tested is 48 864kJ/mol(in HCl solution)and 29 121kJ/mol(in H 2SO 4 solution) The influence factors for adsorption, e.g. negative ion concentration,temperature and competitive ions are investigated更多还原
