| Resumen: | This Part of BS 4427 describes a method for the separation and the determination of the different phosphate forms in sodium tripolyphosphate (pentasodium triphosphate) and sodium pyrophosphate (tetrasodium diphosphate) for industrial use. The procedure specified allows the selective determinations of orthophosphate (Na2HPO4), of pyrophosphate (Na4P2O7) and of tripolyphosphate (Na5P3O10), and also the evaluation of the total content of more condensed forms of phosphates in the absence of tetrametaphosphates and pentametaphosphates.
