Abstract
Complex multi-step processes, with equilibration times varying from mi nutes to weeks, are observed to control trace metal sorption to partic ulate matter. A three-step first order reversible kinetic model is use d to fit mesured data for sorption and desorption over periods of up t o 200h. This is likely to perform better than the equilibrium partitio ning approach under the rapidly changing environmental conditions whic h exist in estuaries. Copyright (C) 1996 Elsevier Science Ltd.
