Ion electrode procedures are described for determining SO 4 , Cl, Ca + Mg, K, and Na for waters of low salinity (<30 ppm). Anion‐cation balances average discrepancies of ±4.2%. Waters derived from glaciers and containing fine rock flour give significantly higher results for Na and K by atomic absorption methods than by electrode methods. It is concluded that suspended mineral matter in glacial waters interferes significantly with atomic absorption alkali determinations and that for the analysis of such waters, ion electrode techniques are superior.
