What is it about?
The article describes a new spectrophotometric method for simultaneous determination of Zn(II), Mn(II) and Fe(II) ions in pharmaceutical preparations. 4-(pyridyl-2-azo)-resorcinol (PAR) was used as complexation agent. In order to separation the overlapped signals the mathematical transformation of spectra was applied.
