Sažetak
A selective spectrophotometric method has been developed for
the determination of cobalt after extraction of its 2-methoxyethyl
xanthate complex into molten naphthalene. Cobalt reacts with this
xanthate in the ratio of 1 : 2 (metal : ligand ratio) in a pH range
of 3.5-9.2 and over an acid range of 2.5-7.0 M. It absorbs strongly
at 355 nm. Beer's law is obeyed over the concentration range of
2.5-46.0 ~ig of cobalt in 10 ml of the final solution. The molar
absorptivity and sensitivity in terms of Sandell's definition are
calculated to be 1.287 x 104 1 mo1-1 cm-1 and 0.0046 μg/cm2 respectively.
Ten replicate determinations of sample solution containing
25 μg of cobalt gives a mean absorbance of 0.546 with a standard
deviation of ± 0.0037 and a relative standard deviation of ± 0.670/o.
Interference by various ions has been studied and the conditions
developed for the determination of cobalt in complex materials
such as alloys.
