Abstract
The sorption of maltol (3-hydroxy-2-methyl-4-pyrone) by Fe-montmorillonite from aqueous solutions is pH dependent. IR and Mossbauer spectroscopy indic ate bonding of maltol oxygen ligands to the interlayer Fe(III). Simultaneou sly maltol releases part of the Fe(III) into the solution. The interaction of the Fe-maltolato complex with Na-montmorillonite occurs by ion exchange.
