The equilibrium and kinetics of sorption of Cu ions at low solution concentration on $Cu^{2+}$-templated poly(4-vinylpyridine) resin were studied. The Langmuir isotherm equation fits the equilibrium sorption data well, while the kinetic data agree with a modified shrinking core model for fluid-solid chemical reactions. Pore diffusion controls the exchange rates at low solution concentration. The diffusion coefficient which lies within the normal expected range for chelating resins increases with increasing solution concentration, besides temperature. This phenomenon is discussed in the light of similar observations reported for ion exchange resins in the literature.
