Identification of mineral waters using impedance spectroscopy and projection to latent structures

Resumo

A method is proposed for the rapid identification of mineral waters by impedance spectroscopy combined with chemometric experimental data processing by projection to latent structures. Measurement conditions are optimized and performance characteristics are estimated. Possibilities of the extraction of qualitative and quantitative information on the concentrations of metal ions and anions in water, determination of the nature of mineral waters, degree of mineralization, and conformity to standard samples are shown.
