The photodegradation of tri-dyes in the real textile effluent of S.I.T.E industrial zone of Karachi city based on central composite design

The study was successfully carried out in the presence of UV light using TiO2 and H2O2 system to purify the real textile discharge from tri-dyes namely Yellow 145(Y145), Reactive Red 195(RR195), Blue 222(Blue222). This work was based on Central Composite Design (CCD) to find out the optimum levels of four factors, namely, pH, TiO2, H2O2 and irradiation time for the effective removal of tri-dyes and chemical oxygen demand (COD) from the effluent....
