The high cost of platinum and increasing demand have prompted the recovery of Pt from low-grade ores and spent catalysts. In the present paper the investigation of solvent impregnated resin (SIR) preparation was conducted. Photoacoustic (PA) and diffuse reflectance spectroscopy (DRS) spectra were recorded for the prepared solvent impregnated resin. Photoacoustic spectra in the infrared area allow to distinguish the differences between the sorbent applied before and after impregnation process. Impregnation of resin is a result of physical sorption of Hostarex A 324 on macroporous Amberlite XAD 7 HP.
