Study on Properties of Extraction Palladium(II) with the New Synthesized Material

Abstract:

In this study, the solvent extraction of Pd(II) from hydrochloric acid solutions was investigated using the new synthesized material, 2-ethylhexyl benzothiazolyl sulfide (EHBTS) which was dissolved in xylene. Pd(II) was strongly extracted by 7% EHBTS in a lower concentration hydrochloric acid solution. Extraction parameters of Pd(II), including EHBTS concentration in different diluents, contact time of aqueous and organic phases, organic/aqueous (O/A) phase ratio and HCl concentration of aqueous phase, were studied. Quantitative extraction of Pd(II) occurred at 0.1 mol.L-1 of HCl concentration, 7% of EHBTS concentration, 1.0 of O/A, 40 min of contact time. In addition，the percentage stripping of Pd(II) could be more than 98% when thiourea concentration was 0.8 mol.L-1. EHBTS can be used more than 8 as extractant to extract of Pd(II) from hydrochloric acid solutions.
