| Abstract: | 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. |
