title: News analytical reagents for europium(III).
abstract: The complexant reactions of 2'-hydroxychalcones with europium(III) are studied by the spectrophotometric method. The apparent formation constants are evaluated using a simple graphical linear method. The sequence of these constant values is explained and compared with aluminium(III) complexant reactions.
