Influence of the Composition of Seawater to the Seawater Direct Electrolysis

The influences of the composition of seawater to the seawater direct electrolysis were discussed. The composition of seawater varies from season to season and from place to place. While the concentration of Cl~- decreases, the electrochemical potential in creases and the current efficiency decreases. The current efficiency increases progressively as the concentration of Mg~(2+) (or Ca~(2+)) concentration does.
