Description

General description

2-Phenyl-5-benzimidazolesulfonic acid has been reported as a UV filter and its removal from aerobically treated gray water by ozonation and adsorption onto activated carbon has been reported. It is a xenobiotic compound detected in gray water from houses and effluents of the biological treatment systems (aerobic, anaerobic, and combined anaerobic+aerobic).

Application

2-Phenyl-5-benzimidazolesulfonic acid may be used for the fabrication of biomimetic sensors used in the determination of 4-methylbenzylidene camphor (4-MBC), an ultraviolet (UV) radiation protector. It may also be used as an analytical reference standard for the quantification of the analyte in gray water, effluents of the biological treatment systems, wastewater treatment plant effluents using different chromatography techniques.
