Abstract

The adsorption of vanadium(V) and 8-hydroxyquinoline-5-sulfonic acid (HQS) on polyacrylonitrile fiber disks filled with an AV-17 (PANV–AV-17) anion exchanger is studied by diffuse reflection spectroscopy. Vanadium(V) at pH 5‒7 is adsorbed on PANV–AV-17; when a HQS solution is applied to the disk, a yellowish green complex compound formed, which changed color to almost black after the treatment of the disk with a HCl solution. The presence of sulfo groups in the HQS molecule ensures the preconcentration of the reagent on PANV–AV-17 disks with the registration of an analytical signal after the treatment of the disk with NaVO3 and 0.1 M HCl solutions. A linear dependence of the analytical signal is observed in the HQS concentration range of 1‒10 μg/mL. The presence of 20-fold amounts (by weight) of 8-hydroxyquinoline (HOQ) does not interfere with the determination. When ascorbic acid is applied to the disk with a vanadium(V)‒HQS‒HCl complex, the color changes from black to green. A test method for the determination of ascorbic acid is proposed. 8-Hydroxyquinoline can be determined by the intrinsic color of the adsorbate on PANV–KU-2 in the range of concentrations of HOQ solution in two drops 5‒100 μg.
