The partial least squares modeling based on singular value decomposition was applied for
the simultaneous spectrophotometric determination of Co (II), Ni (II) and Cu (II) as their
ammonium 2-amino-1-cyclohexan-1-dithiocarbamate complexes. The latent variable
calculation in this partial least squares modeling is not an iterative technique. The detection
limits for Co (II), Ni (II) and Cu (II) were 0.072, 0.021 and 0.063 μg/ml, respectively. The
application of the method was confirmed by analysis of these metals in sample alloys.
