Determination of submillimolar concentration of ferrate(VI) in alkaline solutions by amperometric titration Academic Article uri icon


  • Abstract A new amperometric titration method was developed for quantitative determination of ferrate(VI) (FeVIO42) in the 7.061055.73103 M concentration range. Chromium(III) hydroxide solution was used as the titrant. The diffusion current (Id) had a linear relationship with the concentration of ferrate(VI) and slopes were dependent on the concentration of NaOH. The amperometric titration could detect a lower concentration of ferrate(VI) than could potentiometric and colorimetric titrations. The method was applied successfully to determine concentrations of ferrate(VI), generated electrochemically, in strong alkaline solutions.
