Sequestration of aqueous-bound cadmium ions using ZnO nanoparticle synthesized from Ocimum gratissimum leaf extract: kinetic, isotherm, and thermodynamics studies

:0.99). Thermodynamic studies revealed a spontaneous and exothermic sorption process for the uptake of Cd from aqueous solutions onto the ZnONP-OG. Overall, the results demonstrated that the ZnONPs synthesized from OG were effective in decontaminating Cd from aqueous solutions and could serve as a potent and cheap substitute compared to conventional adsorbents.
