A tantalum(v) oxide impregnated silica gel surface: application as a promising adsorbent for simultaneous heavy metal preconcentration

This article reports on an investigation into the ability of SiO₂–Ta₂O₅ as a new sorbent for simultaneous preconcentration of Cd(ii), Co(ii), Cr(iii), Cu(ii), Fe(iii), Mn(ii), Ni(ii) and Pb(ii) ions from water by the column method and the parameters involved in this process.
