Amperometric complex-formation titrations with a dropping bismuth amalgam electrode in halide medium.
The use of the dropping bismuth amalgam electrode has been investigated for the selective determination of metal ions in the presence of large concentrations of halides by means of amperometric complex-formation titrations, using normal pulse polarography. Concentrations of metal ions down to 3 x 10(-7)M have been determined with adequate accuracy in the presence of about 0.1M chloride or 0.01M bromide. Calculated and experimental current-voltage curves have been compared and found to be in reasonable agreement.
