Abstract
A simple approach to sorption equilibria on Duolite ES 467 has been applied. Values of the Langmuir constants for NiII, CdII, CoII and FeIII have been determined using equilibrium experiments at constant ionic strength and at different temperatures from 20°C to 50°C. Values of the thermodynamic parameters ΔG0, ΔH0 and ΔS0 have been calculated.
