Abstract
The prepared YVO4:Eu3+ nanoparticle was successfully used for the removal of highly toxic Cd2+ metal ion. Batch experiments were performed as a function of various experimental parameters such as effect of pH (2–8), contact time (5–120 min), initial Cd2+ concentration (25–200 mg L−1), and temperature (25–40°C). The equilibrium was established within 90 min where 82% Cd2+ was adsorbed using YVO4:Eu3+ nanoparticles. Kinetic studies showed better applicability for pseudo-second-order model. Langmuir and Freundlich isotherm models were employed for fitting the equilibrium data, and it was found that the Langmuir model fitted the data better than the Freundlich model.
