“…The Nand P profiles are described in another paper (Yonebayashi et al 1994). The Ca, K, Mg, and Na contents did not change appreciably with depth, except for the Ca profile of PN-I treated with lime, and K profile of AB-2, which was reclaimed 2 y ago.…”

“…Peat is a natural substance with lignin, cellulose, and humic materials as its major constituents (Yonebayashi et al, 1994). These constituents feature the presence of polar functional groups such as aldehydes, ketones, and carboxylic, hydroxylic, phenolic acid groups in their molecular structure, which can all be involved in heavy metal adsorption.…”

X-ray absorption spectroscopic study provided an evidence for the competitive adsorption mechanism of Pb, Cu, and Cd on peat. AbstractCombined use of batch equilibration adsorption and X-ray absorption spectroscopy (XAS) was employed to study the mechanisms of competitive adsorption of Pb, 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 Pb > Cu > Cd. Both the adsorbed amount of each metal (q 0 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,1 ) decreased pronouncedly compared to those at high-energy adsorption sites (q m,2 ), indicating that the competitive adsorption of Pb, Cu and Cd occurred mainly at the low-energy adsorption sites. XAS study revealed that both Pb 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 Pb and Cu on peat.
