Ferrochrome electrolysis technology is a novel method for preparing sodium chromate (Na2CrO4). Although the method performs well at soft reaction conditions, controllable process, environmentally friendly production process, etc., the electrochemical oxidation process of metal chromium in NaOH aqueous electrolyte is still unclear. At present, there are few research articles about specific electrochemical oxidation of metal chromium in NaOH aqueous electrolyte. It is, therefore, meaningful to carry out the research in electrochemical oxidation mechanism of chromium. The electrochemical oxidation of metal chromium in 0.01 mol·L-1 ~ 10 mol·L-1 NaOH aqueous electrolytes at 20 °C was studied by …
