Гальванічні промивні води хромування та методи їх сорбційного очищення

Abstract

Considered and analyzed the deep purification of wastewater from chromium ions using the sorption method, the efficiency of which varies from 80.0% to 99.5% depending on the chemical nature of the adsorbent, the size of the adsorbing surface, the structure and properties of pollutants. This method has found wide application for further purification of wastewater from heavy metal ions in Ukraine and abroad. Wastewater containing hexavalent chromium is the most dangerous water, it is discharged into the environment in an insufficiently purified form, which is a problem of international importance.
