Abstract

Acid Orange 7 (A07) has been extensively used in industrial application especially for textiles industries. It was estimated that approximately 10-15% of dye was discharged as effluent without being treated. Combination of Fenton-like reaction with heterogeneous catalyst has been recognized as an effective way in removing organic pollutant. Fe3-xCoxC>4 catalyst has been introduced as promising catalyst by substituting cobalt into the magnetite structure. In this study, detailed investigation on the influence of cobalt substitution was performed in correlation with the catalytic performance of resultant catalyst. The Fe3.xCoxC>4 catalysts were synthesized through the co-precipitation method. The cobalt loading were varied at x value of 0.1,0.2,0.4 and 0.6 respectively. Then, 0.2 g/L of these resultant catalysts were used in the oxidative degradation of A07 at condition of initial pH 3 with H2O2 concentration of 22 Mm. At different x value, Fe3-xCox04 catalyst with x=0.4 exhibited higher performance on catalysis and adsorption at 30.88% and 13.34%, respectively. The analysis shown that at loading x=0.4, the catalyst have high pore size and pore volume at 10.346 nm and 0.0925 cm3/g. Respectively, Fe3.xCoxC>4 catalyst also has better stability compared to pristine magnetite. It can be concluded that the substitution of cobalt provide positive influence toward improvement of catalytic performance.
