Comprehensive Zeta Potential Analysis of Moringa oleifera-Based Coagulants for Heavy Metal Removal

This study investigates the efficacy of Moringa oleifera-derived coagulants for removing Cd, Cr, and Pb from water through zeta potential analysis. The surface charge characteristics of Moringa oleifera seed, gum powder, bentonite clay, and clay-polymer composites are explored, emphasizing their role in coagulation-flocculation processes. The isoelectric point (IEP) is identified as a crucial parameter, underlining its significance in the colloidal system. Results highlight promising heavy metal removal by Moringa oleifera seed, gum, and their composite coagulants. The research offers unique insights into the zeta potential characteristics of these coagulants, emphasizing pH’s importance in heavy metal removal. This holistic examination of Moringa oleifera-derived coagulants presents a promising avenue for sustainable water purification practices.
