Notes:
Summary Vanadyl sulfate, VOSO4, was characterized as the mobile phase for the ion exchange separation of Li+, Na+, NH 4 + , and K+ using indirect photometric detection at 254 nm. Detection limits ranged from 0.2 ppm for Li+ to 1 ppm for K+. Indirect electrochemical detection of these separated cations by reduction of VO (II) to V3+ was compared to spectrophotometric detection. The potential of the vanadate species, HVO 4 2− , for the separation of F−, Cl−, and SO 4 2− , with indirect photometric detection was also demonstrated.
