The analytical utility of chloranil-loaded polyurethane foam in a syringe column was investigated. A rapid method for the determination of micro and semimicro amounts of cerium(IV), vanadium(V) and iron(III) by means of this redox "pulsed" column has been developed. The effects of number of pulses, temperature and concentration of metal ion in solution on the reduction efficiency of the proposed pulsed column were critically studied. Analyses for different concentrations of Ce(IV), V(V) and Fe(III) were successfully carried out with an average relative error of ±2.2%.
