What is BS 4427-11- Different phosphate forms in sodium tripolyphosphate and sodium pyrophosphate about?
BS 4427 discusses methods of test for sodium tripolyphosphate (pentasodium triphosphate) and sodium pyrophosphate (tetrasodium pyrophosphate) for industrial use.
BS 4427-11 is the eleventh part of the BS 4427 multi-series and discusses a method for the separation and the determination of the different phosphate forms in sodium tripolyphosphate (Penta sodium triphosphate) and sodium pyrophosphate (tetra sodium diphosphate) for industrial use.
Who is BS 4427-11- Different phosphate forms in sodium tripolyphosphate and sodium pyrophosphate for?
BS 4427-11 on the separation and the determination of the different phosphate forms in sodium tripolyphosphate and sodium pyrophosphate sodium pyrophosphate is useful for:
- Chemical manufacturers
- Fertilizers manufacturers
- Paint manufacturers
- Soap and detergent manufacturers
- Tar product manufacturers
- Testing Laboratories
Why should you use BS 4427-11- Different phosphate forms in sodium tripolyphosphate and sodium pyrophosphate?
The procedure in BS 4427-11 specified allows the selective determinations of orthophosphate (Na2HPO4), pyrophosphate (Na4P2O7) and tripolyphosphate (Na5P3O10), and the evaluation of the total content of more condensed forms of phosphates in the absence of tetrametaphosphates and pentametaphosphates.
BS 4427-11 provides you with the reagents and apparatus required for the test procedure. BS 4427-11 guides you with the procedure and expression of results. BS 4427-11 helps you determine and separate the different phosphate forms in sodium tripolyphosphate (pentasodium triphosphate) and sodium pyrophosphate (tetrasodium diphosphate) for industrial use.
What’s changed since the last update?
BS 4427-11:1983 supersedes BS 4427-11:1979 which is withdrawn. BS 4427-11:1983 includes some technical changes with respect to BS 4427-11:1979. These include:
- Deletion of a suction device to introduce the solutions into the chromatographic column
- Substitution of a revised typical diagram obtained during the determination of the elution conditions, that corrects the misleading implication that the higher condensed phosphates are eluted by 5 mL of hydrochloric acid solution
