Summary, etc. The photocatalytic activity of TiO<sub>2</sub>/Fe<sub>3</sub>O<sub>4</sub> nanocomposite has been determined. The XRD spectrum and FESEM analysis have been used to evaluate TiO2 / Fe3O4 nanoparticles. The photocatalytic activity of nanoparticles is assessed by degradation of the RR198 solution under the influence of UV-LED radiation. Response Surface Methodology (RSM) is employed to determine the relationships between the studied parameters. The experiments were designed and performed in two ways: One-factor-at-a-time method (OFAT) and Central composite design (CCD). Here nanoparticles with synergistic effect of S<sub>2</sub>O<sub>8</sub><sup>2-</sup> were very successful in eliminating the dye. The results of the RSM model with the two mentioned experiment design methods indicated that the model derived from the CCD method had a better predictive capability and favoured from the ability to generalize to other results rather than OFAT method.
