Abstract
The sorption of Cu(Ⅱ)by loess was investigated experimentally.In general,the measured results were fitted with the conventional Langmuir isotherm very well.However,the further applicability analysis showed that the parameters in Langmuir equation no longer keep their original physical meanings.The parameters in Langmuir equation are characterized more by the precipitation than the adsorption of Cu.
