Study the catalytic activity of CeO2 catalyst for the oxidative degradation of orange g dye in aqueous solution

الملخص EN

The oxidative degradation of Orange G dye catalyst was prepared by precipitation method.

Various physical and chemical properties of the synthesized phase.

The FTIR result showed the effect of calcination temperature for CeO band intensity compared to uncalcined Ce nitrate sample.

Meanwhile, the diffuse spectra at 414 nm with an energy gap of 3.2 ev.

out under various conditions such as, the effects reaction.

The optimum conditions for the highest decolorization efficiency (100%) were achiev G dye with catalyst dosage of 1.5 g/L, pH 2, reaction temperature of 65 °C and 0.1 mL H
