Abstract:
Benzophenone-3 is a well-known molecular UV filter found mainly in commercial cosmetic preparation for sunscreen and skincare. Due to the 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 carcinogenic 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. The presented research aims to examine the possibility of using titanium anode plates for electrochemical degradation of benzophenone-3 in 0.05 M aqueous sodium chloride solution. Electrolysis was performed in galvanostatic mode at a current density of 25 mA cm-2. During 40 minutes of electrolysis, the degradation efficiency of benzophenone-3 is 98.3%. Additional studies of process kinetics show that degradation of benzophenone-3 follows first-order kinetics.
