Investigation Of Benzophenone-3 Electrochemical degradation On Titanium Electrode

Abstract

Benzophenone - 3 is a well - known molecular UV filter, main- ly found in commercial cosmetic preparation for sunscreen and skincare. Due t o increased use of sunscreens, it could be found in surface water and wastewater, which could affect the water quality and human health. Research indicates that benzophenone - 3 act as endocrine disruptor and has a carcinogen- ic and mutagenic effect on humans and other living organisms. As such, poses a health risk to all living beings and need to be removed from the environment. Electrochemical techniques for wastewater treatment of organic pollutants show advantages over commercial techniques as practicality , safety, and simple application on both, small and large systems. Aim of the presented research is to examine the possibility of using titanium anode plates for electrochemical degradation of benzophenone - 3 in 0.05M aqueous sodium chloride solution. Elect rolysis was performed in galvanostatic mode at a current density of 25 mA cm - 2 . During 40 minutes of electrolysis, the degradation efficiency of benzo- phenone - 3 is 98.3 %. Additional studies of process kinetics show that degrada- tion of benzophenone - 3 follow s first - order kinetics.
