Molecular composition of microaggregates from artificial soils based on organic wastes and Fe-rich mud by FTIR analysis

Abstract

The production of technosols for soil restoration constitutes a sound environmental strategy that may also contribute to a suitable disposal of wastes. FTIR analysis of microaggregates from artificial soils, obtained by combining composted organic wastes with Fe-rich mud, suggested the formation of a chemically stable pool of organic matter. The formation of organo-mineral associations was confirmed by gallic acid adsorption on the Fe-rich mud.
