In the present paper,the effect of working electrode materials on the process of electrochemically desulfuration was studied in allkali solution containing sulfide by means of electrolytical cell system with three electrode.The tested working electrodes include platinum,praphite and ruthenium titanium electrodes.Among which the experiment results show that the ruthenium titanium electrode has the highest efficiency to the desulfuration process in a solution of NaOH and Na 2S.By using ruthenium titanium electrode as working electrode an industry simulated device of multistages was set up for electrochemical desulfuration.
