Systematic studies were carried out on the adsorption of the silver thiourea complex on activated carbon. The experimental isotherm data fit the Freundlich isotherm equation. The adsorption rates increased with increasing temperature and decreased slightly with the increase of free thiourea concentration. The concentration of sulfuric acid had little effect on the adsorption rate. Adsorption kinetics correlated well with the Elovich equation, indicating adsorption is the rate-determining step.
