Abstract
Three models for predicting multicomponent equilibrium sorption isothe rms have been tested for the sorption of cadmium, copper and zinc ions onto peat. The models tested were an extended Langmuir isotherm, a si mplified model based on characteristic equilibrium parameters and a mo dified 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.
