This Part of BS 4258 describes a spectrometric method for determination of the iron content of phosphoric acid (orthophosphoric acid) for industrial use. It is applicable to products having an iron content of not lower than 20 mg/kg.
NOTE 1 A reduced lower limit for applicability cannot be quoted for this method because of the risk of interference of phosphate in the development of colour (see clause 2 of BS 6337-3:1983).
NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
