Effect of Modification on the Toxicity of Sorption Materials Intended for Wastewater Treatment

Abstract

The results of an experimental study of chemical and thermal modification of galvanic sludge which is the basis of composite sorption materials intended for wastewater treatment were presented. It was shown that the sorption material based on ferritized galvanic sludge possesses magnetic properties, which allows its extraction from water by magnetic separation. The specific surface area, particle size distribution, and bulk density of the sorption material were determined. Bioassay testing was performed to assess the material toxicity.
