摘要：

Three models for predicting multicomponent equilibrium sorption isotherms have been tested for the sorption of cadmium, copper and zinc ions onto peat. The models tested were an extended Langmuir isotherm, a simplified model based on characteristic equilibrium parameters and a modified extended Langmuir isotherm incorporating an interaction factor. The experimental system is based on the sorption of three metal ions onto peat in single, binary and ternary component systems.
