The voltammetric characteristics of bismuth (III)-oxine in chloroform at the mercury electrode were investigated and a quasi-reversible behavior for Bi (III) oxinate reduction was confirmed. Preceded by the extraction of Bi(III) oxinate in chloroform, differential pulse polarography was developed in the extracs for determination of the trace-bismuth. The linear range of the calibration graph and the detection limit respectively were: 1*10-6 - 5810-5 M and 4.7*10-7M of Bi (III). Suitability and accuracy of the proposed method for determination of trce-bismuth was estabilished by the analysis of a metallic aluminum sample.
