Abstract
The electrochemical preparation of strontium perchlorate, Sr(ClO4)2, from strontium chlorate employing platinum anode and a rotating stainless steel cathode is described. The effect of electrolyte concentration, current density, pH and temperature of the electrolyte and cathode rotation on current efficiency for the preparation of strontium perchlorate was studied. A maximum current efficiency of 42% was achieved corresponding to an energy consumption of 6.1 kWh. kg^(-1).
