AbstractCombined use of batch equilibration adsorption and X-ray absorption spectroscopy (XAS) was employed to study the mechanisms of competitive adsorption of Ph, Cu, and Cd on Danish and Heilongjiang peat in single- and multi-solute systems. The adsorption capacity and initial adsorption rate on the same peat in single-solute systems followed the order Ph > Cu > Cd. Both the adsorbed amount of each metal (q '(m)) and its initial adsorption rate were decreased in multi-solute systems. It was observed that the adsorbed amounts of metals at low-energy adsorption sites (q(m,l)) decreased pronouncedly compared to those at high-energy adsorption sites (q(m,2)), indicating that the competitive adsorption of Ph, Cu and Cd occurred mainly at the low-energy adsorption sites. XAS study revealed that both Ph and Cu were coordinated in peat predominantly to carboxylic moieties without excluding the hydroxyl groups, thereby providing an insight into the mechanism of competitive adsorption of Ph and Cu on peat.
