Separation of Pt(IV), Rh(III) and Fe(III) in acid chloride leach solutions of glass scraps by solvent extraction with various extractants
چکیده انگلیسی
Solvent extraction experiments were conducted to recover pure Pt(IV) and Rh(III) from the chloride leach liquor of glass industry scraps containing a small amount of Fe(III) using Alamine 336, TOPO, TBP and Cyanex 923. The Pt(IV) and Fe(III) were selectively extracted by Cyanex 923 leaving Rh(III) in the raffinate, while only Fe(III) was extracted by TBP. The Pt(IV) in the loaded Cyanex 923 phase was first selectively stripped over Fe(III) by NaSCN and then the remaining Fe(III) was stripped by HCl solution. The Fe(III) in the loaded TBP phase was easily stripped by dilute HCl solution. The McCabe-Thiele diagrams for the extraction of Pt(IV) by Cyanex 923 and of Fe(III) by TBP were constructed. Based on the obtained results, a flowsheet for the separation of three metals from the real leaching solution of glass industry scraps was proposed.
