A new method based on the use of cation imprinted polymers to separate
lanthanum and gadolinium cations is proposed. Using a styrene-DTPA mo
nomer specific of one of these elements, an improvement in separation
selectivity is observed when a tailor-made gadolinium imprinted polyme
r is compared to a non-imprinted or blank polymer. (C) 1998 Published
