On. Kononova et al., PALLADIUM SORPTION ON VINYLPYRIDINE ION-EXCHANGERS FROM CHLORIDE SOLUTIONS OBTAINED FROM SPENT CATALYSTS, Hydrometallurgy, 48(1), 1998, pp. 65-72
The recovery of palladium from spent catalysts has been investigated.
Palladium dissolution was effected using acidic sodium chloride. The i
nitial concentrations in these solutions were (mel/l): Pd, 0.0005-0.05
; NaCl, 2.0-2.3 and HCl, 0.5-2.0 (or 0.02-0.05). The palladium sorptio
n from these solutions was studied under batch experiment conditions o
n vinylpyridine ion exchangers AN-251M, ANKF-5 and VP-14K. (C) 1998 El
