ABSTRACT Calcium peroxide (CaO 2 ) is an environmentally friendly oxidant and can be used to decolorize textile wastewater. In this study, CaO 2 was used directly without any activator to degrade Basic blue 41 (BB41) from simulated textile wastewater (STW), including auxiliary production chemicals. The characterization of the synthesized CaO 2 was investigated by scanning electron microscopy, energy-dispersive X-ray, X-ray diffraction and Fourier-transform infrared spectroscopy analyses. The optimum pH was found to be 7 for the degradation of the BB41. Thermodynamic studies showed that the degradation of the BB41 by CaO 2 is endothermic and spontaneous. The activation energy for the oxidation reaction was found 52.954 kJ mol –1 . 0.4 g CaO 2 was found to be sufficient for the removal of BB41 with 99.6% removal efficiency. The experiments showed that the CaO 2 can effectively oxidize organic-based auxiliary chemicals in STW. Over 80% chemical oxygen demand removal efficiency from STW was obtained with 2.0 g CaO 2 . The study results showed that CaO 2 can be used as an effective and environmentally friendly oxidant for the decolorization of the textile wastewater.
