General description
2-Phenyl-5-benzimidazolesulfonic acid has been reported as UV filter. It is a xenobiotic compound detected in in gray water from houses and effluents of the biological treatment systems (aerobic, anaerobic, and combined anaerobic+aerobic). It is a micropollutant of personal care products and its removal from aerobically treated grey water by ozonation and adsorption onto activated carbon has been reported.
Application
UV absorber
2-Phenyl-5-benzimidazolesulfonic acid was used for the fabrication of biomimetic sensor for determination of 4-methylbenzylidene camphor (4-MBC), an ultraviolet (UV) radiation protector.

Eighteen selected xenobiotics related to personal care and household chemicals (UV-filters, fragrances, preservatives, biocides, surfactants) were measured in gray water from 32 houses and in effluents of three different biological treatment systems (aerobic, anaerobic, and combined anaerobic+aerobic). All selected xenobiotics
