这项工作的目的是研究芬顿反应在处理玛瑙行业产生的废水中的效率。采用不同剂量的芬顿试剂（H2O2和FeSO4）进行实验，并对处理后的废水水质进行色度、浊度、悬浮物、COD、表面张力和污泥生成等方面的分析。结果表明，2 mL·L-1的H2O2（32-36.5%）和0.16 g·L-1的FeSO4用量足以使出水完全脱色，去除悬浮物，降低有机物含量并增加表面张力。采用优化的 Fenton 条件，通过 GC-MS 研究降解过程中残留的有机产物。对芬顿法降解后废水中存在的化合物的质谱分析表明，存在二甲苯、直链和支链烃、酚类化合物和氮化苯酚作为残留化合物。因此芬顿反应可以作为一种潜在的化学氧化剂来处理染料有机废水。 (c) 2005 Elsevier Ltd. 保留所有权利。
The aim of this work was to investigate the efficiency of Fenton's reaction in the treatment of the effluents generated by the agate industry. Experiments with different dosages of Fenton's reagents (H2O2 and FeSO4) were carried out and the treated wastewater quality was analysed in terms of colour, turbidity, suspended solids, COD, surface tension, and sludge generation. Results showed that 2 mL L-1 of H2O2 (32-36.5%) and 0.16 g L-1 of FeSO4 dosages are enough to completely decolourise the effluent, remove suspended solids, reduce the organic content and increase the surface tension. Optimised Fenton's conditions were used to investigate by GC-MS the organic products remaining in the degradation process. The analysis of the mass spectrum of the compounds present in the wastewater after degradation by the Fenton's process showed the presence of xylene, linear and branched hydrocarbons, phenolic compounds, and nitrogenated phenol as residual compounds. Thus Fenton's reaction may be used as a potential chemical oxidant for the treatment of dye organic effluents. (c) 2005 Elsevier Ltd. All rights reserved.
