"Simultaneous Determination Of Mercury(II), Copper(III) And Bismuth(III) In Urine By Flow Constant-current Stripping Analysis With A Gold Fiber Electrode"
Anal. Chim. Acta 1987 Volume 202, Issue 1 Pages 117-122
Huang Huiliang, Daniel Jagner and Lars Renman

Abstract: Urine samples are treated with concentrated nitric acid and potassium permanganate ar 70°C for 10 min prior to injection. The flow electrode system consists of a 10 µm diameter gold fiber working electrode, a glassy carbon reference electrode and a platinum counter electrode. In the fully automated constant-current stripping procedure, the gold fiber is first covered with a fresh gold film after which the sample is electrolyzed for 1 min prior to stripping in 0.1 M hydrochloric acid with a current of 0.1 µA. The procedure is repeated on a spiked sample after which the sample analyte concentrations are evaluated and presented digitally and graphically on a printer/plotter. The results obtained for bismuth, copper and mercury in a urine reference sample were 36.9, 39.7 and 47.7 µg L-1 with standard deviations (n=10) of 3.2, 4.2 and 2.1, respectively. The certified values for copper and mercury were 45 and 51 µg l-1; no certified value was available for bismuth.

"Bismuth(III) Hydride Generation, Its Separation And The Determination Of Bimuth(III) By Atomic Absorption Spectrometry Using Flow Injection"
Analyst 1990 Volume 115, Issue 5 Pages 567-569
Wing-Fat Chan and Ping-Kay Hon

Abstract: Sample (200 µL) containing Bi(III) was injected into a water stream (4.3 mL min-1) and mixed with NaBH4 solution in a reaction coil. From the gas - liquid separator comprising a PTFE membrane backed by a stainless-steel screen (10 mm x 60 mm, 200 mesh), the BiH3 diffused into a N stream (280 mL min-1) to be carried into the absorption cell. The detection limit was 0.17 ng with a rectilinear response up to 50 ppb of Bi, and a sample rate of 300 h-1 was achieved. The method was applied satisfactorily to standard gun-metal. Interference from Cu and other metals can be avoided by using the standard addition method.

"Flow Injection Manifold For Simultaneous Spectrophotometric Determination Of Bismuth(III) And Lead(II)"
Anal. Lett. 1987 Volume 20, Issue 9 Pages 1379-1398
Martinez Calatayud, J.;Mico Albert, R.;Camplco, P.

Abstract: A manifold producing a carrier stream with adjustable pH is described that is based on the merging of two different solution (HClO4 and K H phthalate), one at constant flow rate and one at variable flow rate. This manifold was used for simultaneous determination of Bi(III) and Pb(II) with arsenazo III. The method was valid from 1.0 to 11.0 ppm for Bi(III) and from 1.0 to 12.1 ppm for Pb(II) at pH 2.15.

"Continuous-flow And Flow Injection Stripping-voltammetric Determination Of Silver(I), Mercury(II) And Bismuth(III) At A Bulk Modified Graphite-tube Electrode"

Abstract: In continuous-flow analysis (CFA) sample solution [in 0.1 M acetate medium of pH 4.32, 0.1 M phosphate buffer of pH 5.5, and Britton-Robinson buffer of pH 3.8 for Ag(I), Hg(II), and Bi(III), respectively] was pumped through the flow cell for 10 min at 1.41 ml/min and accumulation was carried out under open circuit conditions. Then deaerated stripping solution [70 mM HCl, 75 mM KBr, 100 mM HNO3, and 1 M HCl for Ag(I), Hg(II), and Bi(III), respectively] was passed through the cell at 0.72 ml/min and after 15 s the appropriate deposition potential was applied [-0.15, -0.20, and -0.50 V (vs. Ag/AgCl) for Ag, Hg and Bi, respectively] for 15 s. Finally, differential-pulse anodic-stripping was carried out commencing at the deposition potential of the metal. For FIA (details given), the analysis was very similar and calibration graphs (CG) were linear for 5 nM- to 1 µM-Ag(I), 10 nM- to 2 µM-Hg(II) and 100 nM- to 5 µM-Bi(III). The respective detection limits (DL) were 0.18, 1.9 and 9.5 nM; RSD (n = 6) were 2.53-10.5, 2.57-5.77 and 5.97-7.9%, respectively. For FIA, CG were linear from 50 nM- to 5 µM-Ag(I), 100 nM- to 5 µM-Hg(II), and 5-50 µM-Bi(III), and the respective DL were 11, 20 and 1200 nM. RSD (n = 6) were 6.32, 6.44 and 7.9%, respectively.
