M. Rajan et Vm. Shinde, SELECTIVE DETERMINATION OF COBALT(II) IN ALLOY SAMPLES USING SYNERGISTIC EXTRACTION, Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 35(3), 1996, pp. 251-252
A method is proposed for the synergistic extraction and spectrophotome
tric determination of divalent cobalt using benzoylacetone and pyridin
e dissolved in toluene as extractants. The optimum extraction conditio
ns have been established and the method has been applied for the analy
sis of real samples.
