  • Spectrophotometric determination of arsenic and antimony

    When sodium tetrahydroborate(III) is used for hydride generation in the spectrophotometric determination of arsenic as a complex with silver diethyldithiocarbamate, significant antimony interference may occur. This can be overcome by reading the absorbance at a wavelength other than the absorption

  • A method of processing arsenic intermediates antimony

    The essence of the proposed method lies in the fact that in alkaline solution (the filtrate) antimony and arsenic, represented by antimonite, arsenite and toolame, are oxidized. Teocoli decompose and sulfide enters sulfate, and antimonite and arsenite are oxidized to antimonates and Arsenates.
