Abstract
A kinetic method for simultaneous determination of multielements is proposed, and a procedure for simultaneous determination of uranium(VI) and iron(II) is established based on their inductive effect on the chromium(VI)-iodide redox reaction in weak acidic medium. The reaction was monitored with the stopped-flow spectrophotometric technique by using I −3 -starch complex as indicator. The calibration graphs are linear for 0–3.6 μg.cm−3 U(IV), and 0–2.5 μg.cm−3 Fe(II), respectively. Most foreign ions, except for V(IV), Sb(III), do not interfere with the determination.
