Elution and Carbon Reactivation Resource book

conditions, elution (desorption) of gold from the carbon occurs. The main factor that makes desorption or stripping a simple process is the fact that gold will only adsorb onto carbon at low temperatures. If the temperature of a solution and carbon mixture is increased, the gold will readily desorb from the carbon into the solution. Temperature
