Preceded by the extraction of Bi(III) oxinate in chloroform, differential pulse polarography was developed in the extracts for determination of the trace-bismuth. The linear range of the calibration graph and the detection limit respectively were: 1´10-6 -5´10-5 and 4.7´10-7 M of Bi(III). Suitability and accuracy of the proposed method for determination of trace-bismuth was established by the analysis of a metallic aluminum sample.  }, keywords = {Voltammetry in chloroform,Bismuth(III) oxinate,Chloroform,Aluminum,Differential pulse polarography,Bismuth determination}, url = {https://ijcce.ac.ir/article_9971.html}, eprint = {https://ijcce.ac.ir/article_9971_d79d426fa1a46f24492b40f4a3cc28d2.pdf} }
