Research/Original Article (دارای رتبه معتبر)
The applicability of Zeolitic Imidazolate-67, Modified by Fe3O4 Nanoparticles, was studied for the removal of benzyl paraben from wastewater by adsorption method studied using response surface methodology (RSM). For the adsorption characterization of the adsorbent used in benzyl paraben adsorption, BET, FTIR, XRD, and SEM analyses were performed. The impacts of variables including initial benzyl paraben concentration (X1), pH (X2), adsorbent dosage (X3), and sonication time (X4) came under scrutiny using response surface methodology (RSM). The values of 10 mg L-1, 0.03 g, 7.0, and 4.0 min were considered as the ideal values for benzyl paraben concentration, adsorbent, pH, and contact time, respectively. Adsorption equilibrium and kinetic data were fitted with the Langmuir monolayer isotherm model and pseudo-second-order kinetics (R2: 0.999) with maximum adsorption capacity (92.0 mgg-1), respectively. The predicted values were in agreement with experimental values obtained for the components of the mixture. The values at the optimized process conditions indicated a commercially viable route for optimal removal of dyes from wastewater.
