Abstract: The simultaneous determination of bismuth(III) and cobalt(II) with  methylethylenediaminetetraacetic acid by the zero-crossing method is described. The method is suitable for analysing 0.04-0.20 mg ml-1 of bismuth(III) and 0.06- 0.24 mg ml-1 of cobalt(II) in the pH range 4.0-9.0. The two analytes are stable up to 100°C for at least 24 h. The method has been applied to different aqueous matrices and the results are in good agreement with those obtained by AAS (typical deviations ~ 0.003-0.004).
