A novel metal–organic framework (MOF), with the formula [Cu(II)L]n (L=4, 4′-diamino diphenyl sulfone), has been synthesized conventionally andhydrothermally methods and characterized by FT-IR, PXRD, EDX, and SEMtechniques. The results MOFs were applied for photodegradation of MethyleneBlue (MB). The influence of affecting variables, such as initial MB dyeconcentration (2–8mg L−1), Cu(II)-MOF mass (0.01–0.03 mg), pH (3.0–9.0), andtime of irradiation (30–90 min). The photocatalytic degradation efficiency wasinvestigated by the central composite design (CCD) methodology. The resultsof CCD analysis for optimum values of variables revealed that Cu(II)-MOF masswas 0.025g, the initial concentration of MB was 3.51 mg L−1, pH was 4.50 andirradiation time was 75 min.Under the optimum conditions, the photocatalytic MBdegradation percentage at the desirability function value of 1.0 was found to be70%. In addition, the obtained R2 value of 0.97 in the regression analysis showeda high photocatalytic efficiency of the proposed method for MB degradation.
