| Abstract: | To solve the problems existing in the traditional production technique of chromium trioxide,a new green technology of producing chromium trioxide from sodium dichromate with an electro-catalysis synthesis method was studied in a self-made electrolytic bath.Experiments showed that the electro-catalysis synthesis process of chromium trioxide might be characterized by the variation of cell voltage with reaction time.The math models of the variation of cell voltage and the change rate equations of which were es... |
