Experimental central composite design (CCD) and the response of
Three independent variables such as the volume of toluene in solvent system, chamber saturation time and wavelength were investigated. Of numerical and categorical factors. Central composite design is a response surface design which apart from the 3 level factors has axial or star point. The axial or star point usually denoted as (α) increases the number of levels.
