Abstract

Abstract Due to increasing health issues because of heavy metal emissions through different industrial processes becoming serious threats to the sustainability of the ecosystem. The objective of this study was to treat heavy metal-containing wastewater that discharges from industrial effluents. A locally available and inexpensive biomass-based material was used as an adsorbent material for the effective adsorption of Cu from an aqueous solution. The prepared bio-adsorbent was evaluated under different operating conditions to optimize the adsorption efficiency. The results showed that in low concentration solution, the adsorption efficiency is around 60% while in almost all other conditions efficiency varies between 40-50% depending on the operating conditions. To understand the mechanism of Cu adsorption on bio-adsorbent various kinetics and isotherm analysis were performed. The pseudo-second order (PSO) kinetic model's best fit (R2 = 0.991) suggests that chemisorption controls Cu adsorption on PWD. An exothermic process with reduced unpredictability is shown by a thermodynamic study at the solid-liquid interface. Harkins-Jura and other non-linear isotherm models, in particular, suited the adsorption data better and showed the effectiveness and dependability of non-linear methods for Cu removal by PWD adsorbent.
