Full TextAbstract
The SBA-15 is significant mesoporous silica with exclusive and important properties of highly ordered mesopores, profusely large surface area and huge pore volume which render it as sorbent for wide applications such as heavy metals removal. In this study, synthesis and preparation of SBA-15 and its nanocomposite containing polypyrrole (Ppy) was discussed, and their capability to removal of mercury (Hg) from aqueous solution was studied. Polypyrrole was prepared by chemical oxidative polymerization of pyrrole using FeCl3 as an oxidant and coated on SBA-15 (prepared with sol-gel method). The removal of Hg was investigated using Ppy, and Ppy/SBA-15 nanocomposite, respectively. The products were investigated in terms of morphology and chemical structure with transmission electron microscopy (TEM) and BET test, respectively. Batch studies were performed to evaluate the influence of various experimental parameters like pH, adsorbent dosage and contact time. Optimum conditions for Hg removal were found to be pH= 8, adsorbent dosage of 1 g/L and equilibrium time 60 min.
