- Abstract
The techniques for iron determination in natural waters using cyclic (CVA) and stripping (SVA) voltammetry were optimized. It was shown that CVA method on the Pt-electrode can be used to determine simultaneously the iron (II) and (III) in water analysis with iron concentration > 0.6 mg/ dm3. The optimum conditions stripping voltammetric determination of iron (III) using catechol as an complexing agent on the mercury film graphite electrode were found. The detection limit is 0.001 mg/ dm3. SVA method was used for total iron content to be determined in drinking and surface waters of the Krasnoyarsk region. It was shown that iron concentration in samples of surface water in the two sites of the Yenisei River, upstream and downstream of Krasnoyarsk City and the city tap water meets the standards. It was found that the iron concentration in samples of surface water in Igarka City and tap water of Lesosibirsk City exceeds the antipollusion standarts.
