Nonlinear Isotherm Adsorption Modelling for Copper Removal from Wastewater by Natural and Modified Clinoptilolite and Glauconite

Abstract

The paper presents the results of the Cu2+ adsorption on natural and thermally/microwave-treated clinoptilolite and glauconite. XPS experiments were performed. The relationship between the adsorbed matter and the equilibrium concentration in wastewater is described by four two-parameter isotherm models and four three-parameter adsorption isotherm models.
