Abstract
Triphenylphosphine oxide dissolved in toluene has been used for the ex traction of bismuth and antimony from halide media. After stripping fr om the organic phase, antimony and bismuth have been determined by pot assium iodide and thiourea methods respectively. The optimum extractio n conditions have been ascertained. Log-log plots indicate the probabl e extractable species to be MX(3).2TPPO. The method has been applied f or the determination of the studied metals in spiked samples leaded br ass and leaded gunmetal.
