| Abstract | ||
| Sodium perchlorate has been prepared electrochemically from sodium chloride solutions in one step by passing a direct current through the solution , in the presence of certain addition agents (like sodium fluoride). A laboratory electrolytic cell has been designed to obtain experimental results for the preparation of sodium perchlorate. A solution of sodium chloride (290 g/l ) and sodium fluoride (2 g/l ) is electrolyzed in a batch wise. A stainless steel cathode and Graphite substrate lead dioxide (GSLD) anode are satisfactory . The influence of anodic current density , temperature ,and pH of electrolyte on current efficiency of sodium perchlorate formation were studied. The current efficiency of about 68% was obtained by using (GSLD) anode. | ||
