The reaction of di-μ-hydroxo-bis(diphenanthrolinoferric) chloride with iodide in aqueous solutions at pH 3.0 to 6.5 under the action of light radiation at wavelenghts shorter than 590 nm was studied. A procedure is suggested for the quantitative determination of iodide in concentrations of 0.7-9.4 μmol l-1, based on the evaluation of the slope of the time dependence of absorbance at 530 nm.
