Beschreibung

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.[1] It is a xenobiotic compound detected in gray water from houses and effluents of the biological treatment systems (aerobic, anaerobic, and combined anaerobic+aerobic).[2]

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,[2] effluents of the biological treatment systems,[2] wastewater treatment plant effluents using different chromatography techniques.
