In the present work Response Surface Methodology based on the central composite design (CCD) has been applied to the modeling and optimization of photocatalytic decolorization efficiency (Y %) of C.I.Basic Blue 41 (BB41) using TiO2 aqueous suspension in tubular solar photoreactor equipped with compound parabolic collectors (CPCs). The factors (variables) studied were the catalyst concentration (X1), initial dye concentration (X2), flow rate (X3), initial pH (X4) and the accumulated visible energy incident on the reactor QV,n (X5). Results showed a high coefficient of determination , thus confirming adequacy of adjustment of the second-order regression model with the experimental data. the main significant reaction parameters were accumulated visible energy incident on the reactor QV,n (X5), catalyst concentration (X1), initial dye concentration (X2), interaction between catalyst concentration and QV,n (X1X5) and interaction between catalyst concentration and initial pH (X1X4).
