Desorption occurs in soil washing when the washwater (and associated additives) is mixed with the soil. During this stage, the contaminants are desorbed from the soil particle surface. Dissolution or solubilization of the contaminants can occur due to pH changes that result from acid-base reactions of the washwater. The washwater may also cause the formation of complexes with the contaminants ...
