Abstract: To reduce the total number of experiments so as to achieve highest degradation or removal of Congo red dye using Ruthenium and Nickel Oxide impregnated over Activated Carbon as a Catalyst; 4 factors (Sonication time; concentration of dye. Amount of catalyst and Hydrogen Peroxide quantity) and 2 variables were selected (16 Experiments) using factorial design. Using the Statistic tools; we obtained various plots including ANOVA; Fit model; Interaction between the factors ; individual effect of the factors and finally the validation of the Design of experiment using the Regression equation obtained.
