• 論文の詳細を見る

• The anion-exchange distribution ratios of tri-, tetra-, and pentaphosphate were determined in a Dowex 1-X4-potassium chloride system at different pH by the batch method. The difference between the mean charges of the phosphates in resin phase and solution was explained in terms of a higher pH of resin phase than that of the solution. pH dependence of the separation factors for tri- and tetraphosphate and for tetra- and pentaphosphate was estimated from the batch equilibrium data, and the relative elution positions of these phosphates were confirmed by the practical chromatographic runs.
