Article Preview

A new adsorption agent, nanosized strontium titanate immobilized on the silica gel G (GSTO) was prepared, and it was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The ability of the new adsorption to remove heavy metal Pb, Cd, Zn, Cu, Ni and Mn from water samples was assessed. The research results displayed that adsorbent has the highest adsorption capacity for Pb, Cd, Zn, Cu, Ni and Mn in ions mixture system. Optimal experimental conditions including pH and contact time have been established. Desorption studies were carried out successfully with diluted HNO3 solutions. Thus, nano-strontium titanate immobilized on the silica gel G is favorable and useful for the removal of these heavy metal ions, and the high adsorption capacity makes it a good promising candidate material for Pb, Cd, Zn, Cu, Ni and Mn removal.
