ELECTROLYSIS OF AQUEOUS SOLUTION OF POTASSIUM CHLORIDE |
摘要 |
<p>An electrolysis of an aqueous solution of potassium chloride is carried out by employing a fluorinated cation exchange membrane having an ion-exchange capacity of 0. 8 to 2. 0 meq/g dry polymer and having carboxylic acid groups as functional groups and maintaining a concentration of an aqueous solution of potassium hydroxide in a cathode compartment in a range of 20 to 45 wt.% and maintaining a calcium concentration in the aqueous solution of potassium chloride to lower than 0.05 mg/liter. The purification of the aqueous solution of potassium chloride to reduce the calcium concentration is carried out in a system comprising a chelate ion-exchange substance.</p> |
