Bio-Sorbent Derived from Annona Squamosa for the Removal of Methyl Red Dye in Polluted Waters: A Study on Adsorption Potential

Abstract

Sorbent got from leaves and barks of Annona squamosa has been investigated for its sorption capacity towards Methyl Red (MR) utilizing artificially arranged recreated squander waters. Different components influencing adsorption, viz., initial color concentration, contact time, adsorbent dosage, along with the impact of temperature were assessed. The equilibrium of adsorption was demonstrated by Freundlich; Langmuir, Temkin, and Dubinin-Radushkevich isotherms. Pseudo-first order, pseudo-second order, Weber and Morrish intraparticle diffusion, Bangham's pore dispersion and Elovich equations were applied in order to distinguish the rate and kinetics of adsorption progression. Interference of a five-fold abundance of regular anions and cations present in common waters, have been examined. Cation like Ca2+, Mg2+ and Cu2+ have showed some impedance, however, Fe2+ and Zn2+ have synergistically maintained the greatest extraction of the MR. The methods developed were effectively applied to some effluent. The results of experimental data were found appropriate to the pseudo-first order kinetic model. Correlation coefficient (R2) and dimensionless division or separation factor (RL) values have affirmed that adsorption obeys Langmuir adsorption showing monolayer development.
