Modified agricultural waste adsorbent for zinc ions removal from aqueous solution: Equilibrium, kinetics, and thermodynamics investigation

Abstract

The current research signifies potential bio sorbent (banana and Pomegranate peel) With a view for zinc ions adsorption as of aqueous solution. Mass, zinc ion concentration, pH, time, and temperature parameters were examined. The highly beneficial requirements for zinc ion adsorption are 10 ppm as preliminary concentration, 0.21 g as pomegranate and banana rinds dosage and 5.5, 5.23 as pH for banana and Pomegranate rind. Elimination results follow the Langmuir replica with qmax of 25.64 mg/g for banana and 41.66 mg/g for Pomegranate rind. The elimination process kinetic was equipped well via second -order equivalence. It was examined that the zinc ion adsorption procedure on both bio sorbents is instinctive procedure, endothermal for banana and pomegranate rind. A distinctive enhancement in the adsorptive shell was observed once the adsorption procedure that revealed through scanning electron microscope.
