On the use of a small synthetic calibration set for the simultaneous spectrophotometric multivariate determination of Ca2+ and Mg 2+ in groundwater: Chemical and spectral considerations

A critical evaluation of chemical and spectral considerations for the simultaneous spectrophotometric determination of calcium and magnesium in groundwater samples with methylthymol blue (MTB) using a calibration set composed by synthetic standards is presented. The method is based upon the spectral...
