Adsorption of AuCl-4 by kaolinites; effect of pH, temperature and kaolinite crystallinity

Adsorption of the AuCl4- complex by kaolinites of different crystallinities (Kao-1 and Kao-2) from 100 mL of AuCl3·HCl·4H2O solutions containing 10,000, 500 and 50 µg/L Au and 1 g of kaolinite was measured at pH 3 to 9 at ambient temperature and 120°C. Adsorption from the 50,500 and 10,000 µg Au/L s...
