【Abstract】 The adsorption kinetics, thermodynamics of crosslinked polystyrene-supported triethylenetrtramine resin for Cu²⁺ are investigated. The temperature has an inconspicuousness effect on the saturated adsorption capacity of resin for Cu²⁺. The results show that the adsorption kinetic is controlled by liquid film diffusion. The adsorption process can be described by Langmuir and Frundlich models. The apparent activation energy（Ea）,ΔG,ΔH, entropy change are 19.050,-6.984,-2.929kJ/mol,ΔS is 13.608J/（mol·K）.更多还原
