title: [Determination of cobalt in solidified resin promoter by successive extraction and FAAS].
abstract: A new method had been investigated for the analysis of micro-amount of cobalt in solidified resin promoter. Methyl isobutyl ketone (MIBK) was used in 1 mol.L-1 NH4SCN medium followed by 4 mol.L-1 nitric acid back extraction step, then analysis by flame atomic absorption spectrometry. The results indicated that the method was accurate and the interference with concomitant in solidified resin promoter was negligible. The method had a recovery of 96.2%-104.6%.
