چکیده
The applicability of Albizia Stem Bark Lebbeck Modified by Fe2(MoO4)3 nanocomposite, was studied for eliminating Methyl Violet dye from industrial wastewater. Identical techniques including (IR, XRD, and SEM) have been utilized to characterize this novel material. The impacts of variables including initial Methyl Violet concentration (X1), pH (X2), adsorbent dosage (X3), and sonication time (X4) came under scrutiny using central composite design (CCD) under response surface methodology (RSM). The values of 20 mgL-1, 0.03 g, 5.0, 3.0 min were considered as the ideal values for Methyl Violet 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 (120.4 mgg-1), respectively. Thermodynamic parameters (ΔG°: -9.26 kJ mol-1, ΔH°: -29.24 kJ mol-1, ΔS°: -131.49 kJ mol-1 K-1), also indicated Methyl Violet adsorption is feasible, spontaneous and exothermic. Overall results confirmed that Albizia Stem Bark Lebbeck Modified by Fe2(MoO4)3 nanocomposite is an effective adsorbent for removing the toxic dyes from an wastewater.
