摘要：

We report the role of ultrasonic procedure on the recovery of Platinum (Pt) from spent removing catalyst of Pt/Al2O3. In this study, the Pt was extracted by combining acid leaching of aqua regia and ultrasonic cleaning procedure. The frequency-dependent ultrasonic (low and high-frequency modes) showed a significant change in the Pt content on the Al2O3 ball. The morphological analysis showed that the higher frequency of the ultrasonic led the larger number of Pt recovery due to the higher agitation from the ultrasonic wave. This study gives a detail characteristic and modification of the Pt during the recovery, which is the key role on optimization of recovery of the Pt from spent removing the catalyst of Pt/Al2O3.
