Notes:
Summary Thallium (I) forms the Bismuthiol II complex of composition C8H5N2S3 Tl. At about 10° C, it is completely precipitated at high acidity as well as at high alkalinity and the precipitate can be dried at any temperature up to 250° C. The complex is highly stable in presence of a tartrate or citrate, cyanide and complexone III and because of the unusual stability it can be estimated and separated from practically all ions. Bismuthiol II thus can be considered as a highly selective reagent for thallium (I) in presence of a mixture of cyanide and tartrate maintained at aph between 7 and 9.
