Abstract

This study explores the potential of fluted pumpkin stem powder (FPSP) as an eco-friendly and cost-effective adsorbent for the removal of heavy metals from pharmaceutical wastewater. The research investigates the adsorption capacity of FPSP for iron (Fe) and lead (Pb), examining the influence of contact time, adsorbent dosage, agitation speed, and pH. Chemically activated FPSP demonstrated significant adsorption capacities, achieving removal efficiencies of up to 85.263% for Fe and 90.000% for Pb under optimal conditions. Results indicated a direct proportional relationship between contact time, adsorbent dosage, agitation speed, and adsorption efficiency; as these variables increased, so did the adsorption efficiency. Conversely, pH showed an optimal efficiency at 7.5, with a decrease in efficiency observed at pH levels above this value. The study employed adsorption isotherms and kinetic models to explain the mechanisms underlying the adsorption process, such as the role the roles of ion exchange, complexation, and surface adsorption. The findings suggest further investigation into the regeneration and reuse potential of FPSP, as well as its application in treating various contaminants and scalability for industrial use. This research provides a comprehensive understanding of the efficacy and practicality of FPSP in wastewater treatment, promoting the utilization of renewable resources and advancing sustainable practices.
