Abstract

This study explores the green synthesis of lead nanoparticles and their application in degrading the AZO dye Nicoracine under solar irradiation. UV-Visible spectroscopy confirmed nanoparticle formation with a peak at 248 nm, indicating SPR. FTIR revealed functional groups from plant extracts aiding stabilization. XRD analysis showed a crystalline structure, while SEM and AFM indicated irregular shape and rough surface. The nanoparticles exhibited significant catalytic activity, enhancing Nicoracine degradation via solar light, facilitated by ROS generation. Kinetic analysis suggested a pseudo-first-order reaction model. This green synthesis method offers a sustainable solution for wastewater treatment and industrial pollution mitigation.
