A catalytic oxidation and degradation process of Na alkylbenzenesulphonate(NABS) in aqueous solution was experimentally studied by using NaClO as an oxidant, the type TU catalyst selected from a set of experiments, and the IR analysis to monitor the process. The factors affecting the removal of NABS from water were also studied. The results show that the type TU catalyst has a better ability to catalytically oxidize NABS in water, generally with a removal of about 80%, and almost all of the NABS in water c...
