Effects of Electrodes on the By-product CHCl3 Produced in the Electrochemical Disinfection

Objective To evaluate the effects of electrodes on the production situation and the by-product CHCl₃ produced in the electrochemical disinfection processes.Method Taking filtering water,the graphite and Ti(matrix)-Ti are used as electrodes,adjusting the current analyzing sample in different time,under different the production of CHCl₃ conditions are reviewed.Results The results show that the production of CHCl₃ in the electrolysis used Ti(matrix)-Ti is more than that used the graphite.The more the current,the more the production of CHCl₃.With the length of electrolysis time,the production of CHCl₃ increase,and it is the most production on 20 minutes.Conclusions In the electrochemical disinfection processes,we should use the graphite and the current should be under 1 mA/cm2,the leng th of electrolysis is under 10 minutes.
