چکیده

The photo catalytic oxidation of Surfactant Hexadecyltrimethyl-ammonium bromide in aqueous diluted solution has been investigated. Compressed air was used as oxidant and the temperature was maintained at 25-30°C. Effect of UV rays alone and in combination of hydrogen peroxide (H O ) and titanium 2 2 dioxide (TiO ) on Hexadecyltrimethyl-ammonium bromide (C H NBr) was recorded. Finally, from HPLC 2 19 42 and IR analysis the intermediates products have been detected prior to the total Hexadecyltrimethylammoniumbromide mineralization.
