Abstract:
Objective To evaluate the effects of electrodes on the production situation and the by-product CHCl
3 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 CHCl
3 conditions are reviewed.
Results The results show that the production of CHCl
3 in the electrolysis used Ti(matrix)-Ti is more than that used the graphite.The more the current,the more the production of CHCl
3.With the length of electrolysis time,the production of CHCl
3 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.
