Abstract

This research paper explores the use of DD3 mesoporous kaolin, synthesized from CTAB, as an adsorbent for ibuprofen (IBP). It focuses on a unique method for improving the adsorption process. The mesoporous DD3 was characterized by Small and Wide-angle X-ray Scattering and Transmission Electron Microscopy (TEM). Box–Behnken experimental designs were used to model key quantitative factors in the adsorption process, thereby reducing the number of experiments and thus the cost of the experiments to be conducted. Three variables were taken into account: pH, initial IBP concentration and the dose of adsorbent. The validity and reliability of the model used for this study were confirmed by an analysis of variance (ANOVA test). This study focuses on the optimization of adsorption conditions, particularly the estimation of the minimum amount of adsorbent required for a maximum initial IBP concentration. The developed model is effective as evidenced by the impressive adsorption capacity of 330.22 mg/g obtained under the optimal conditions identified through the experimental design. This result underlines the promise of mesoporous DD3 to be an effective adsorbent for the treatment of IBP-contaminated waters, offering prospects for sustainable and economically viable environmental applications.
