Among the various methods for determining zirconium is the amperometric titration of excess EDTA with bismuth nitrate. Such a titration was first used with a dropping mercury electrode. Here the authors investigate the conditions for titrating with a bismuth indicator electrode because a number of difficulties -current oscillation, mercury toxicity -- arise in work with the dropping mercury electrode. It is determined that the bismuth indicator electrode can in fact be used to determine zirconium by inverse amperometric titration of excess EDTA with bismuth nitrate.
