- •
Zn vapor pretreatment is proposed for the recovery of precious metal catalysts.
- •
Extraction of the metals from simulated catalysts is examined in acid solutions.
- •
Enhancement of the extraction by the pretreatments is observed in aqua regia.
- •
Hydrochloric acid is also found able to dissolve precious metals.
- •
Effects of pretreatments are discussed from the viewpoint of catalyst structure.
