In the present study, the applicability of PSF/Fe2O3 mixed matrix membrane synthesis for eliminating humic acid rapidly from aqueous solutions. Identical techniques, including FT-IR, XRD and SEM has been utilized to characterize this novel material. The investigation showed the applicability of PSF/Fe2O3 mixed matrix membrane as an available, suitable and low-cost adsorbent for proper deletion of humic acid from aqueous media. Also, the impacts of variables including initial humic acids (HAs) concentration (X1), pH (X2), adsorbent dosage (X3), sonication time (X4) came under scrutiny using central composite design (CCD) under response surface methodology (RSM). Additionally, the impacts of the pH of the solution, the amount of nanoparticles, concentration of humic acids (HAs), and contact time were investigated. The experiments have been designed utilizing response surface methodology. In this current article the values of 12 mg L-1, 0.03g, 7.0, 4.0 min were considered as the ideal values for humic acids (HAs) concentration, adsorbent mass, pH value and contact time respectively. The kinetics and isotherm studies proved the appropriateness of the second-order and Langmuir models for the kinetics and isotherm of the adsorption of humic acids (HAs) on the adsorbent. The adsorbent was proved to be recyclable for more than once. Since almost 99.5% of humic acids (HAs) was deleted with ideal adsorption capacities of 105 mg g−1 for humic acid (HAs). The overall results confirmed that PSF/Fe2O3 mixed matrix membrane could be a promising adsorbent material for humic acids (HAs) removal from aqueous solutions.
