The applicability of Zeolitic Imidazolate-67 Modified by Fe3O4 Nanoparticles, was studied for eliminating butyl paraben dye from aqueous solutions. Identical techniques including BET, IR, XRD, and SEM have been utilized to characterize this novel material. The impacts of variables including initial butyl paraben concentration (X1), pH (X2), adsorbent dosage (X3), and 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 butyl paraben dye, and contact time were investigated. The experiments have been designed utilizing response surface methodology. In this current article the values of 10 mgL-1 , 0.03 g, 7.0, 4.0 min were considered as the ideal values for butyl paraben 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 butyl paraben on the adsorbent. The adsorbent was proved to be recyclable for more than once. Since almost 99.5% of butyl paraben was deleted with ideal adsorption capacities of 110 mgg−1 for butyl paraben in no time, therefore not only the short-time adsorption process was considered an advantage but also vantages in using Zeolitic Imidazolate-67 Modified by Fe3O4 Nanoparticles like being recyclable, safe, and cost-efficient made it a promising and powerful material for the aqueous solutions. تفاصيل المقالة

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. تفاصيل المقالة
