Applicability, adsorbent chitosan@Fe2 (MoO4)3 nanocomposite for removal of textile reactive red198 dye from wastewater
In this study, the applicability of adsorbent Chitosan@Fe2(MoO4)3 nanocomposite was employed as a novel adsorbent for removing Reactive red198 dye from wastewater. Identical techniques, including BET, FT-IR, pH zero, and SEM, have to characterize this unknown material, and the effect of initial conc...

| description | In this study, the applicability of adsorbent Chitosan@Fe2(MoO4)3 nanocomposite was employed as a novel adsorbent for removing Reactive red198 dye from wastewater. Identical techniques, including BET, FT-IR, pH zero, and SEM, have to characterize this unknown material, and the effect of initial concentration (2–50 mgL−1), with temperature (298–308 K) on adsorption potential was analyzed in a batch system. The variables' impacts include Reactive red198 dye concentration, adsorbent, pH, and time (10 mgL−1, 0.15 g, 4.0, and 40.0 min). Based on the received data, the adsorption mechanism of Reactive red198 dye on the Chitosan@Fe2(MoO4)3 nanocomposite adsorbent agrees well with the Langmuir adsorption model isotherm (qm, exp ≈ qm, cal= 69.0 mgg−1), and pseudo-second-order kinetics (R2: 0.998). The results of the thermodynamic parameter showed a negative enthalpy (- 2.92 kJ mol−1), a negative Gibbs free energy (−15.25 kJ mol−1), and negative entropy (−39.28 kJ K−1 mol−1). This led to the conclusion that the adsorption process is energetically possible, and exothermic was also spontaneous. The values at the optimized process conditions indicated a commercially viable route for the optimal removal of dyes from industrial wastewater. The results indicated that Chitosan@Fe2(MoO4)3 nanocomposite showed great potential as an affordable and efficient adsorbent for treating wastewater. |
