PARAMETRIC STUDY FOR SALINE WATER ELECTROLYSIS .3. PRECIPITATE FORMATION AND RECOVERY OF MAGNESIUM SALTS

In this paper, the third in a series, the effect of some operating variables on precipitate formation (cathodic fouling) during saline water electrolysis is studied. The most important among these are electrolyte concentration, current density and amount of electricity. The change in pH value during electrolysis is reported. Precipitates are collected and samples are analyzed for their Mg content. Proposals are made to utilize the Mg(OH)2 precipitates as a useful by-product of the saline water electrolysis process.
