A Method of Concentrating the Major Impurities Contained in Ice by Ion Exchange
Abstract This note gerscribes a method for concentrating Na, K, Ca, and Mg impurities in samples of snow and ice for analysis by atomic absorption in flame photometry. The cations are fixed on a Dowex 50 ion-exchange resin then selectively released and separately analysed by atomic absorption. This...

| Summary: | Abstract This note gerscribes a method for concentrating Na, K, Ca, and Mg impurities in samples of snow and ice for analysis by atomic absorption in flame photometry. The cations are fixed on a Dowex 50 ion-exchange resin then selectively released and separately analysed by atomic absorption. This method allows the simultaneous treatment of a large number of specimens with concentration factors which can reach 60 to 75 and with very low risk of contamination or loss of the specimens. |
