Abstract The high concentration Fe3+ in sample had interference on the determination of iron species by spectrophotometric method in which 1,10-phenanthroline was used to as a chromogenic agent. The F− could mask absolutely the effect of Fe3+ when F−/Fe3+ molar concentration ratio was 13.3. The temperature or light did not affect the masking action of F−. Low temperature and dark conditions favored the stability of chromophoric complex. This method is suitable for the measure of iron species where the concentration of Fe3+ is far more than that of Fe2+ in samples.
