- 論文の詳細を見る
The conversion of cobalt(II) and nickel(II) ions collected on the ion exchange resin into the chelate compounds with trifluoroacetylacetone (Htfa) has been studied in various solvents. In the presence of pyridine, cobalt and nickel ions were quantitatively extracted from the resin into organic phase in the form of the base adducts [Co(tfa)<SUB>2</SUB>(py)<SUB>2</SUB>] and [Ni(tfa)<SUB>2</SUB>(py)<SUB>2</SUB>], respectively. The thermogravimetric and gas chromatographic behaviors of these compounds have been investigated. A gas chromatographic separation of [Ni(tfa)<SUB>2</SUB>] from [Co(tfa)<SUB>2</SUB>] was successfully performed.
