Abstract
The heterogeneous catalytic oxidation of chromotrope 2B (C2B) dye withH2O2 and the aluminum oxide hydroxide (AlOOH) modified with ammoniacomplexes of CuII, CoII, NiII, and CrIII (AlOOH/[Mn+(amm)m]) as catalystswere studied. The AlOOH/[CuII(amm)4] is the most efficient catalyst andtherefore it was chosen as the potential catalyst for the oxidative degradationof C2B in an aqueous solution. The AlOOH/[CuII(amm)4] was characterizedby Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD),scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), andtransmission electron microscopy (TEM), techniques. The rate of reaction wasdependent on the type of the metal complex supported on the AlOOH, initialconcentration of the dye and H2O2, catalyst dose, pH, the concentration ofNaCl, and temperature. The catalytic activity of the AlOOH/[Mn+(amm)m]according to the kind of metal ion decreased in the order: CuII > CoII > CrIII >NiII. Other catalysts consisting of the AlOOH supported with CuII complexedwith ethylenediamine, ethanolamine, 1,3 propanediamine, and 1,4butanediamine, (AlOOH/[CuII(amine)m]), were also investigated. The activityof the (AlOOH/[CuII(amine)m]) as catalyst according to the type of ligandfollowed the order: 1,4 butanediamine > 1,3 propanediamine > ethanolamine> ethylenediamine > ammonia. The reaction rate increased with increasing thecatalyst dose, concentration of H2O2, C2B, and NaCl, pH, and temperature.
