Effect of the dose of the reducing agent on the properties
of magnetic sorbents from the deironing plant wastes

Summary

The results of the synthesis of sorbents prepared from the deironing plant wastes for the purification of oily wastewater using various doses of the reducing agent are presented. The reducing agent used was glycine, urea, citric acid, and hexamethylenetetramine with an «oxidizing agent – reducing agent» mole ratio equal to 1 (f = 1) and 3 (f = 3). The study and comparison of the properties of synthesized magnetic sorbents obtained at different initiation temperatures of an exothermic synthesis reaction with an «oxidizing agent – reducing agent» mole ratio equal to 1 (f = 1) and 3 (f = 3) were carried out: total static exchange capacity, specific surface area and oil capacity.
