Dissolution of noble metals in highly concentrated acidic salt solutions

Tijdschriftbijdrage - Tijdschriftartikel

Highly concentrated solutions of AlCl3·6H2O and Al(NO3)3·9H2O were investigated for Au and platinum group metals dissolution. 95% Pd was leached from spent automotive catalysts in 15 min at 80 °C, while Pt required longer times; Rh dissolution was <20%. Au dissolution from wires required 24 h. Pd recovery was investigated by reductive precipitation.
