Abstract

The process of the adsorption of Fe(III) cations from aqueous solutions with concentrations of 50–400 mg/L by shale from the Kotsebinskoe deposit in Saratov oblast and by its ash was studied. The isotherms of absorption were constructed, and it was established that the adsorptive capacities of the shale and its mineral component for the cations of Fe(III) were 16 and 5 mg/g, respectively. For this reason, these materials can be used as adsorbents for the purification of wastewater.
