Bismuth 223.1 air/acetylene Sample preparation. Dissolve 2.000 g of sample in 12 ml of hydrochloric acid, 6 ml of nitric acid and 20 ml of water in a PTFE beaker. Evaporate the solution to 10- 12 ml, cool, add 1 ml of hydrofluoric acid dropwise and boil for five minutes. Cool, add 5 ml of 1% boric acid solution and dilute to 50 ml. Background correction using a UV continuum source is advisable for bismuth... 

In powder mixtures, atmospheric moisture or water of crystallization from another ingredient is sufficient for sodium bicarbonate to react with compounds such as boric acid or alum. In liquid mixtures containing bismuth subnitrate, sodium bicarbonate reacts with the acid formed by hydrolysis of the bismuth salt.

Tin ions are reduced to tin hydride from a boric-acid-buffered medium by means of sodium borohydride, transferred to a heated quartz cuvette by a current of inert gas, decomposed thermally, and the absorption of the atoms is measured in the beam of an atomic-absorption spectrometer. In the hydride technique, the element which is to be determined is volatilized as a gaseous hydride and in this way separated off from the matrix. Interference may occur if there is a considerable excess of elements such as antimony, arsenic, bismuth, mercury, selenium or tellurium which can also be volatilized with this technique. Above all, heavy metals such as copper and nickel in the solution have a disturbing effect during hydride formation itself. Interference due to phosphoric acid and hydrochloric acid may also be observed. It is therefore vital to check the method by the addition technique. 

Tartrates give soluble, more or less stable, complexes with miscellaneous cations such as copper, bismuth, and iron, with some metallic hydroxides, acids (such as boric acid), and antimony oxide. The cations become masked by complexation. The identity reaction is carried out, according to the European pharmacopeia, with Fenton s reagent (ferrous sulfate and perhydrol). In a first step, dihydroxyftimaric acid is formed ... 

Fused salt solutions may be found in which the solubility of these oxides is appreciable at high temperatures and from which crystals grow as the solution is cooled. Some of the fluxes which have been used for growth of the oxides of concern here are (a) potassium nitrate-sodium nitrate, (b) lead fluoride-bismuth oxide, (c) lead oxide-bismuth oxide, and (d) lithium hydroxide-boric acid-molybdenum oxide. Temperatures frequently are in the range of 1300°C.
