STUDY OF THE MECHANISM OF DECOLORIZATION OF THE AZO DYE ORANGE G IN AQUEOUS SOLUTION VIA A HETEROGENEOUS UV/FENTON-LIKE REACTION CATALYSED BY IRON PILLARED MONTMORILLONITE

  • 摘要: 以高活性铁柱撑蒙脱石(Fe-Mt)为催化剂,采用非均相UV/Fenton反应体系对含橙黄G(OG)染料废水进行氧化脱色处理研究.实验结果表明,当温度30℃ 和OG浓度50 mg/L确定后,pH 3.0、H2O2浓度20.0 mmol/L和Fe-Mt用量1.0 g/L为最佳脱色条件,180 min后OG的脱色率为99.7%.上述反应条件下,非均相Fe-Mt催化光助-Fenton体系对橙黄G的脱色反应遵循两阶段准一级反应动力学.
    Abstract: The azo dye Orange G (OG) in wastewater was treated via heterogeneous UV/Fenton-like reaction catalysed by a highly catalytic active iron pillared montmorillonite (Fe-Mt). The results showed that the pH 3.0, H2O2 20.0 mmol/L and Fe-Mt 1.0 g/L are the optimum conditions for the OG decolorization (i.e., 99.7% after 180 min) if the temperature and OG concentration were kept constant at 30℃ and 50 mg/L, respectively. Under the above conditions, the OG decolorization followed the two-stage pseudo-first-order kinetics in the heterogeneous UV/Fenton-like reaction system.
