Sh. Lee et al., Precipitation characteristics of palladium from a simulated radioactive liquid waste by ascorbic acid, KOR J CHEM, 16(2), 1999, pp. 166-169
The precipitation characteristics of palladium (Pd) from a simulated radwas
te solution by ascorbic acid was investigated. Pd was selectively precipita
ted by the reduction reaction of Pd with ascorbic acid. When the nitric aci
d concentration in the 8 component system was below 2.0 M? Pd over 99.5 % w
as selectively precipitated at an ascorbic acid concentration above 0.06 M,
while other elements mainly remained in solution. The precipitation yield
of Pd by ascorbic acid decreased with the increase of the nitric acid conce
ntration.
