T. Khayamian et al., Simultaneous spectrophotometric determinations of cobalt, nickel and copper using partial least squares based on singular value decomposition, TALANTA, 49(3), 1999, pp. 587-596
The partial least squares modeling based on singular value decomposition wa
s 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 mo
deling is not an iterative technique. The detection limits for Co(II), NI(I
I) and Cu(II) were 0.072, 0.021 and 0.063 mu g/ml, respectively. The applic
ation of the method was confirmed by analysis of these metals in sample all
