Sažetak

This paper deals with the removal of Nb content from chemically leached solutions of titanium wastes using static ion exchange technology. The chemically leached solutions contained 2 g/L of Nb. The investigations involved the optimization of process parameters, such as contact time at different concentrations of niobium at room temperature. Sorption experiments are performed to evaluate the optimum conditions at a concentration of HCl 3,0 M, 1,0 g resin dose for 3,5 h contact time at room temperature. The maximum sorption capacity reaches to 0,089 g/g. Kinetics studies were proposed for the process by pseudo-first-order, pseudo-second-order, and intraparticle diffusion models.
