Abstract
A successful construction project has many important components, one of which is labour. Many The discharge of heavy metals from galvanized industrial processes into water bodies presents a significant environmental hazard due to their toxicity, persistence, and bioaccumulation potential. Despite the availability of various physicochemical techniques for industrial wastewater treatment, many small to large-scale industries struggle with the high operational costs and technical complexities involved. This research work aims to evaluate the remediation potential of Banana Peduncle, identify optimal conditions for biosorption, and analyze the potential mechanisms in the adsorption process. A quantitative experimental research design was adopted to evaluate the biosorption capacity of banana Peduncle. The study involved: Collection and preparation of biosorbent (banana Peduncle), collection and analysis of galvanized industrial wastewater, batch adsorption experiments, characterization of raw adsorbents (Banana Peduncle) and analysis of metal concentrations after treatment. The raw banana Peduncle (BP) was analyzed and compared for their adsorption capacities. The effluents of the industrial wastewater samples from Prism Steel Rolling Mill, Osogbo Road, Ikirun Ifelodun Local Government Area, Osun State, Nigeria were collected and examined under the Atomic Absorption Spectrophotometry (AAS) analysis to determine the initial concentration of the heavy metals present. The adsorbent sample was examined under FTIR and SEM machine to measure the morphological surface for the adsorption process. The variables which influence the process of adsorption were the dosage of the adsorbent, contact time and the rate of agitation of the wastewater treatment. The initial concentration of heavy metals present in industrial galvanize wastewater sample, shows the presence of Zinc(70%), Manganese(0%), Lead(0%), Copper(2%), Iron(26%), Chromium(1%), and Cadmium(0%), with Zinc has the highest concentration, lead has the lowest concentration and cadmium was not detected in the samples. The balance of the adsorption process was related to the initial ions concentration of the metal, dosage of adsorbent, contact time, and the rotating speed. Based on the laboratory scale batch adsorption experiments conducted, the Banana peduncle demonstrated a high remediation potential or biosorption efficiency at raw state at the following optimal conditions; 0.2g, 100min and 100rpm for adsorbent dosage, contact time and rotating speed respectively with over 90% removal which aligned with Muthusamy et al. (2024). Further study should be carried out on carbonization and activation of Banana Peduncle as adsorbent.
