| مستخلص: | The high cost and increasing demand have prompted the recovery of platinum from low-grade ores and spent catalysts. Platinum exist in chloride solutions in the anionic form, therefore anion-exchanging is a better method than cation exchanging for sorption of platinum(IV) ions. Therefore applicability of four anion exchangers Duolite A 30 B, Lewatit MP 62, Lewatit MP 64 and Purolite A 520E were studied. The FT-IR/PAS spectra were recorded by means of a Bio-Rad Excalibur 3000MX spectrometer equipped with photoacoustic detector MTEC300. The DRS (diffuse reflectance spectrometry) spectra of three anion exchangers Lewatit MP 62, Lewatit MP 64 and Purolite A 520E are similar but spectra of anion exchangers Duolite A 30B is different. The differences in spectra can be result from skeletons of anion exchangers. Recorded FT-IR/PAS spectra allow to distinguish the differences between applied anion exchangers before and after sorption of platinum(IV) ions. In all spectra the biggest differences could be noticed in the OH and CH2stretching region. |
