In this study, cross-linked polystyrene beads were synthesized by conventional free-radical suspension polymerization, and the resulting beads were subsequently coated by polyaniline via polymerization of aniline. Sieved polymer beads with outer diameter in the range of 0.5- 0.8 mm were used for the further study. The surface morphologies of the polymer beads before and after the coating were studied by SEM and TEM. The adsorption efficiency of the polymer beads toward silver ion as nanoparticles was studied at various different conditions: temperature, pH, concentration of silver ion, and contact time. The experimental results will be presented in details. |
