M. Yui et al., A PRELIMINARY INVESTIGATION ON THE DETERMINATION OF LANTHANOIDS, THORIUM AND URANIUM IN BRINE AND DEPOSIT OF A SALT LAKE IN CHINA, Journal of radioanalytical and nuclear chemistry, 231(1-2), 1998, pp. 83-86
A brine sample and two deposit samples of a salt lake in China were an
alyzed for their contents of lanthanoids (Ln's), thorium and uranium b
y neutron activation analysis. Five Ln's were determined at sub ppb le
vels. Th and U contents were at about the same levels as those of Ln's
. The lanthanoid abundance patterns (Ln pattern) of the three samples
are similar to each other, each having a negative slope in the light L
n region. There seems no substantial difference in distribution betwee
n the solution (brine) and solid (deposit) phases among Ln's.
