2.5. Cu(II) was masked with thiourea. EDTA interferes
strongly as it forms stronger complexes with these metal
ions.

APPLICATIONS
The proposed method was validated by the analysis
of Co(II) and Ni(II) ions in alloys. An aliquot of the sample
solution was analyzed by the procedure described above af-
ter adding a suitable masking agent. The concentrations of
Co(II) and Ni(II) were determined from the plots of the sec-
ond derivative amplitudes at 361 and 426 nm, respectively.
The results for the simultaneous determination and certi-
fied amount present in the sample are given in Tables 3 and
4.

The relative error was calculated for the two ions.
Five replicate measurements were carried out to test the ac-
curacy and precision. The relative standard deviation for si-
multaneous determination was calculated [Tables 3 and 4].

Simple and selective procedures for individual deter-
minations of cobalt and nickel using first- and second-order
derivative spectrophotometry as well as their simultaneous
determination by second order derivative spectrophotom-
etry were established with morpholinedithiocarbamate
(MDTC) in sodium lauryl sulphate (SLS) micellar media.
This method shows a wide linear range of quantitative esti-
mation and is more sensitive as compared to a reported
method.43 The limit of detection of Ni(II) is lower for this
method as reported by Sozgen et al.44 The method was ap-
plied to assays of cobalt and nickel in alloys. The analytical
results were satisfactory. The proposed method should be
useful for accurate, precise, rapid, simple and selective de-
terminations of cobalt and nickel in their alloy samples.
