Response surface methodology for decolourisation of leather dye using ozonation in a packed bed reactor
Ozonation of tannery dye Acid Black 52 in a packed bed reactor has been examined to study the effect of operating variables pH, dye concentration and contact time. In this study, the effect of operating variables on the removal of colour and chemical oxygen demand (COD) was studied using 2 3 central...

In this study, the effect of operating variables on the removal of colour and chemical oxygen demand (COD) was studied using 2
3
central composite designs using Minitab 15 software. The operating variables were analysed based on the removal efficiency of colour and COD. Experimental results were analysed by regression analysis and analysis of variance statistical methods. The optimum conditions for maximum colour removal (100 %) and COD removal (61 %) were found to be at pH: 1.96, dye concentration: 1,159 mg/L, contact time: 10.6 min (min) and at pH: 4.8, dye concentration: 1,159 mg/L, contact time: 17 min, respectively. The experimental values were in good agreement with the predicted values and the model is found to be highly significant with the correlation coefficient of 0.94 for both colour and COD removal. |
