Abstract
⺠The PVA matrix gel beads entrapping the micro-droplets of tricaprylylmethylammonium 2-(methylthio) benzoate ([A336][MTBA]) were prepared and characterized by FTIR, SEM and TGA. ⺠The influence of the uptake conditions was investigated including aqueous pH, PVA/IL dosage, the content of [A336][MTBA] and initial mercury (II) concentration. ⺠Maximum Hg (II) adsorption capacity obtained was 49.89 mg g-1 at pH 5.8. ⺠The selectivity of the PVA/IL beads towards Hg (II), Pb (II) and Cu (II) was Hg > Pb > Cu.
