THE DETERMINATION OF BISMUTH IN BISMUTH CONCENTRATES BY CHELATOMETRIC TITRATION by A. Hitchen* and G. Zechanowitsch** ABSTRACT Two methods for the determination of bismuth in bismuth concentrates are described, both based on titration of the bismuth with sodium ethylenediamine-tetraacetate (EDTA).

In one method. A rapid and simple general complexometric method was presented for the determination of bismuth, titanium and aluminium in laboratory synthesized alloys similar to those of some bauxites, clay, ilmenite, Portland cements and ceramic by: 6.

Accepted 8 August ) Summary A new chelatometric method for the determination of Bi in bismuth-base alloys, low-melting alloys and reagent-grade bismuth salts is proposed. It is based on the chelation of Bi (III) with HEDTA, which is added in substoichiometric amount in perchloric acid medium to eliminate the interfering side-reactions Cited by: 5.

Summary. A method is described for the chelatometric titration of bismuth(III) with biamperometric indication. It is applied to ores and concentrates and can also be used in presence of interfering elements (as Zr, Tl, In, Mo, Cu, Fe).Cited by: 1. Fairly large salt complexes of strictly stoichiometric composition were obtained and used for the heterometric determination of minute quantities of bismuth.

A critical study has been made ofR. Berg andO. Wurm's method for the determination of bismuth as HBiJ4 oxin.

The indirect method in which the excess of iodide is back titrated is recommended particularly in the determination of very small amounts of bismuth. Low results are obtained when the chloride concentration is greater than about 0,1N Cited by: 2.

Abstract. To enable high-speed analyses in the preparation of high-purity bismuth and bismuth oxide, we have developed an atomic absorption technique which ensures Ag, Cr, Cu, Fe, Mg, Mn, Ni, Pb, and Te detection limits in the range 2 × 10 −7 to 2 × 10 −5 wt %.

The technique was used to assess the purity of bismuth and bismuth oxide in metal refining and Cited by: 5. Hematoxylin is suggested as an indicator in the titration of several metals with EDTA.

Bismuth and zirconium were readily determined in acidic medium. Several other metals also gave color reactions, but the color changes on addition of EDTA were not by: 5.

The reaction between bismuth nitrate and ferrocyanides of alkali metals such as sodium, potassium, lithium and ammonium, has been studied potentiometrically using platinum as an indicator electrode in conjunction with a saturated calomel electrode through KNO3 bridge.

When only traces of a precipitate are got it must be tested.

The bismuth precipitate is readily soluble in dilute nitric acid. GRAVIMETRIC DETERMINATION. The bismuth having been separated and dissolved in nitric acid is precipitated (after dilution) by the addition of carbonate of ammonium in slight excess, and boiling.

Bismuth: extraction; Brife introduction; Bismuth is extracted from its ores by dry, wet, or electro-metallurgical methods, the choice depending upon the composition of the ore and economic conditions.; The dry process is more frequently practised, due to the easy reducibility of the oxide and sulphide, together with the low melting-point of the metal, which renders it possible to.

A simple extractive spectrophotometric method for the determination of bismuth has been developed. It is based upon oxidation of bismuth(III) to bismuthate with potassium periodate at pH 7–8.

The resulting species is then extracted with tetramethylammonium iodide in chloroform followed by direct spectrophotometric measurement at nm. The optimum Cited by: 6. A successive complexometric determination of the components of bismuth- lead alloys in a nitric acid solution, using xylenol orange as an indicator, is.

weld joint penetration shape of stainless steel in case of gas tungsten arc (GTA) welding has been extensively studied and clarified (Refs.

This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Bismuth .Bismuth's lack of malleability does, however, make it unsuitable for use in expanding hunting bullets.
