title: Determination of bismuth by electrochemical stripping analysis; elimination of interferences by using a mercury film electrode modified with tri-n-octylphosphine oxide, and application to copper alloys.
abstract: A mercury film electrode modified with a film consisting of tri-n-octylphosphinc oxide in a poly(vinyl chloride) matrix is used for a galvanostatic stripping determination of bismuth in copper and copper alloys. The method can be used to determine from 0.002 to 0.5% of bismuth. It is very selective, simple and rapid. The precision and accuracy are good and the only serious interference is caused by tin(IV).
