Abstract:The action state of Na+has been discussed according to the point of view that sodium in pure aluminium melt exists in ionic state. By orthogonal experiment, effects of direct current density, treating time and treating temperature on the amount of removed sodium have been studied , and the mechanism of removal of sodium has been analysed theoretically.
