Abstract

The sorption properties of materials formed after the extraction of humic substances (HSs) from caustobioliths, that is, the dehuminated caustobiolith (DC) residues insoluble in acids and alkalis, as promising secondary humic raw materials for the production of preparations for environmental protection were studied. The main factors responsible for the sorption activity of DCs with respect to nonparamagnetic and paramagnetic metal ions were substantiated from the standpoint of the preparation of sorption materials of different genesis from DCs.
