Lv. Nair et Zr. Turel, SUBSTOICHIOMETRIC SEPARATION OF CO(II) USING 3,4-DIAMINOBENZOPHENONE, Journal of radioanalytical and nuclear chemistry, 229(1-2), 1998, pp. 199-201
A rapid and simple method has been developed for the precipitation of
Co(II) with 3,4-diaminobenzophanone. The effect of various parameters
as pH, temperature, time of heating, anions and interference of cation
s have been evaluated. The stoichiometry of the metal to reagent was f
ound to be 1:2.
