[Spectrofluorimetric study of trifluoroacetylacetone (TFA)-gadolinium(III)-CTMAB system and application].
The determination of microamount gadolinium(III) by fluorescence method was studied based on complex formation Gd(III)-CTMAB-TFA at pH7.2. Beer's law is obeyed in the range of 0. 005-0.04 microg/mL Gd(III). The detection limit is 0.003 microg/mL. The method is used to determine microamount gadolinium of rare-earth mine with satisfactory result, and compared with that of ICP-AES method.
