Arising from more and more severe environmental pollutions

fresh water resources suffering from being lack of supply

becomes a problem.Exploration of new technologies is of importance to effectively solve this situation

in particular those for desalination of seawater.In this manuscript

a home-made electrophoresis apparatus of vertical electric field

was applied to investigate the desalinat-ing synthetic seawater

on basis of chlorine anion.Effect of initial concentration of chlorine anion

re-tention time and applied voltage on the desalination ratio

energy efficiency(mass of migrated chlorine anion at positive electrode region per electric power)and distribution ratio was investigated.The elec-trophoresis apparatus has four outlet regions of positive region

negative region

central region

and ad-jacent region between two electrodes

of which central region represents target collection region for desalinating synthetic seawater.It showed that with an increase in initial concentration of chloride ani-on at inlet

the desalination ratio at central region reduced and the energy efficiency gradually in-creased

and the distribution ratio at positive region decreased

but that at the rest three regions in-creased.When retention time increased

the desalination ratio at central region apparently increased up to 69.5%

the energy efficiency gradually reduced

the distribution ratio at central region and negative region decreased

but that of positive region and adjacent region between two electrodes increased.If the applied voltage increased

the desalination ratio at central region gradually increased up to 13.9%

the energy efficiency slowly reduced

the distribution ratio at positive region increased

that at negative region and adjacent region between two electrodes slightly decreased

and that at central region in-creased and decreased afterward.
