The conditions for the coprecipitation of arsenic and antimony with trace amounts of tungsten and iron in the form of PbWO4 and Na3FeF6 are found. The introduction of hydrofluoric acid in the deposition of macrocomponents results in the formation of precipitates with the lowest specific surface area and porosity, which contributes to the inhibition of the coprecipitation of the analytes (As and Sb). We prepared certified reference materials of ferrotungsten composition according to the developed procedure for the determination of arsenic and antimony by inductively coupled plasma atomic emission spectrometry (ICP–AES). The difference between the found and certified concentrations of analytes does not exceed the values specified by GOSTs. The method of simultaneous ICP–AES determination of arsenic and antimony with preliminary separation of the main components is applicable to the analysis of materials and alloys with high contents of iron and tungsten.
