Abstract
PURPOSE: To always effectively reduce hexa valent chromium and to remove it, by adding the reducing agent, corresponding to the concentration of Cr6+ in the electrolytic processing waste liquid and precipitating Cr(OH)3 and then, adding the precipitant, corresponding to the amount of decomposition products (SO2 4 - etc.) of reducing agent
