Degradation of sodium alkylbenzenesulfonate (ABS) in the Fenton reagent in the presence of Cl- ions has been studied. An anionic surfactant sodium alkylbenzenesulfonate (C11-C14) has been selected as a model compound. The effect of individual components of the reactive system (H2 O2 , H2 O2 /Cl- , Fe2+/H2 O2 , Fe2+/H2 O2 /Cl- ) on the degree of ABS degradation has been determined. The degree of ABS degradation has been found to be affected by the presence of Cl- ions and the mutual molar ratios of individual components of the system studied. Moreover, it influences on the composition of the post-reaction mixture. The use of the Fenton reagent in the presence of Cl- ions resulted in the formation of chloroorganic compounds in the solution studied. 2,4,6-trichlorophenol was identified in reaction products and its presence was confirmed using the HPLC - MS method and by HPLC with an internal standard. No chloroproducts were identified during degradation of ABS by the system H2 O2 /Cl- . When only H2 O2 was applied, the concentration of the surfactant was unchanged.
