The chromatographic behaviour of some cations and anions has been examined on layers prepared from 1:9 mixtures of a synthetic inorganic ion-exchanger (stannic arsenate or tin(IV) molybdosilicate, synthesized under different experimental conditions) with silica gel, alumina, or cellulose, with tri-n-butyl phosphate-formic acid as mobile phase. Several binary separations of analytical interest were achieved on these blended adsorbent phases. The effect of pH on the separation of IO3- from NO2- and BrO3- in the presence of cations was also examined. Quantitative determination of IO3- on mixed stannic arsenate-alumina, 1:9, was also performed success-fully.
