Özet
This study aims to evaluate the effectiveness of pyromellitic diimide carboxylic acid-derived with high retention capacity MOFs as adsorbents for contaminant removal, employing CV as a model pollutant. The adsorbents were synthesized by individually treating the organic linkers with Cu(II) solution at 100–110 °C for 12 h. The characterization of the adsorbents was conducted using FTIR, SEM, PXRD, TGA, BET/N2 surface area analysis, zeta potential measurement, and potentiometric titration. The specific surface areas were determined to be 780.64 m2/g for PDBA-Cu and 445.69 m2/g for PDPA-Cu. The sorption properties of the produced adsorbents were analyzed, considering contact time, initial concentration, pH, and temperature. The adsorptions fitted to the PSOM, exhibiting k values of 0.001 and 0.002 for PDBA-Cu and PDPA-Cu, respectively, in conjunction with the presence of pore diffusion. The CV adsorption on PDPA-Cu conformed to the Freundlich isotherm and had Langmuir characteristics for PDBA-Cu. The Qmax values were yielded as 322.58 mg/g for PDBA-Cu and 400.00 mg/g for PDPA-Cu at 313 K. The maximum adsorptions were achieved at pH levels between 2 and 7 for PDBA-Cu and between 2 and 9 for PDPA-Cu. Electrostatic and π-π interactions have played a role in the CV adsorption on fabricated MOFs. The adsorptions were optimized via modeling with Response Surface Methodology and Box-Behnken Design, based on the critical process variables of contact time, temperature, and initial dye concentration. The findings of this study validated the superior efficacy of the synthesized MOFs in eliminating cationic organic dyes and their applicability in treatment methods.
