TREATMENT TECHNOLOGIES FOR CHROMIUM HEXAVALENT
Journal Title: Azerbaijan Chemical Journal - Year 2017, Vol 0, Issue 1
Abstract
A survey and analysis have been made of existing technologies in reduction of toxic Cr(VI) penetrated into water and soil with wastes of the aluminium plant to practically harmless Cr(III). Most of these technologies do not free the drinking water and soil from Cr(VI). In addition they are expensive. The aim of the work is to reveal the most efficient reducing technology for Cr(VI). Such technology turned to be one based on the chemical method (nanotechnology)
