PHOTO-DEGRADATION AND OPTIMISATION MODELLING OF REACTIVE RED 190 DYE USING A RESPONSE SURFACE METHODOLOGY

In present study, the efficiency of advanced oxidation processes (AOPs) was appraised for the degradation of Reactive Red 190. A factorial design (2(n)) and multivariate analysis were used for optimisation of H2O2, UV exposure time, pH, shaking and temperature. The dye removal was achieved up to 98.5% at optimised conditions with a rate constant of 0.04354 min(-1) The H2O2 percentage, UV irradiation time, pH of solution, shaking speed and temperature levels for the maximum degradation were found to be 3.74%, 100 min, 4.2, 81 rpm and 42 degrees C, respectively. The results showed that response surface methodology was an efficient tool for determining the efficiency of AOP for the degradation of Reactive Red 190.
