Abstract:The kinetics of gold adsorption and elution with a new type of C410 resin was studied. The experimental results show that the adsorption and elution can be described by the Boyd diffusion equation for liquid films. The adsorption rate of gold decreases with increasing HCI concentration. The diffusion coefficient of adsorption is K= 4.83 × 10-4 sec-1  and the apparent enthalpy of adsorption ΔH is 16.05 kJ / mol. The distribution ratio of gold adsorption increases with the temperature. It is shown that the adsorption were of gold with C410 resin is a heat-absorbing reaction. The elution characteristics of gold with thiourea solution were also studied.
