A study of wastewater purification from Zn2 + ions by nanosorbent, obtained by electroerosion dispersion

Abstract

Сurrent state and efficiency of existing sorbtion methods of industrial wastewater treatment are considered. The influence of important parameters for sorbtion process - ratio of metal ion and nanosorbent concentrations in solution, as well as the method of sorbent addition into wastewater on degree of its purification was studied. The most effective results of water purification were achieved with usage of freshly obtained powder of electroerosive dispersion (EED) of iron in water in the form of a suspension at ratio of the concentration of Zn2+ ions and nanosorbent powder 1:10. It Under such conditions a high degree of removing as 98% is determined, and obtained purified solution meets the standards of rising water at galvanic facilities, regarding of Zn2+ content.
