水中烷基苯磺酸钠的催化氧化处理研究

Study on the Catalytic Oxidation of Na Alkylbenzenesulphonate in Aqueous Solution.

研究水中烷基苯磺酸钠的催化氧化过程,所用氧化剂为NaClO;催化剂为通过实验筛选的“TU”型催化剂。水中烷基苯磺酸钠的催化氧化降解过程用红外光谱作了分析,同时,也分析了诸因素对水中烷基苯磺酸钠去除效果的影响规律。研究结果表明,“TU”型催化剂对水中的烷基苯磺酸钠有较好的催化氧化能力,去除率通常可达80％左右,经催化氧化后,水中的烷基苯磺酸钠几乎全部被氧化成为简单的无机物和微量的羰基化合物。

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 can be degraded by the catalytic oxidation into simple inorganics and less carbonyl compounds.
