USING "ELSIKAT" SORBENTS FOR ION CHROMATOGRAPHIC RESOLUTION AND DETERMINATION OF ALKALINE AND ALKALINE EARTH ELEMENTS
Correlations between retention characteristics of Li+, Na+, NH4 +, K+, Mg2+, Ca2+, Sr2+, Ba2+ and molar masses, ionic radiuses, hydration enthalpies and entropies of alkaline and alkaline earth elements were studied. Chromatographic parameters were calculated. Possibility of ion-chromatographic determination of Li+, Na+, NH4 +, K+, Mg2+, Ca2+, Sr2+, Ba2+ ions using "Elsikat" sorbents and conductometric detection was estimated.
