Аннотация
New single-stage method was developed for chemical utilization of wastewater containing 0.25 to 400 g L–1 of chromium in terms of chromium anhydride with the us of sulfuric acid and steel cuttings. The method makes it possible to convert hexavalent chromium into easily used ferrochromium precipitates. It was found that there occur periodic synchronous concentration fluctuations of Cr(VI) and Cr(III) up to, respectively, 400 g L–1 and 150 mg L–1 in the course of reduction of hexavalent chromium with the use of steel cuttings in sulfuric acid solutions.
