Tag Archives: 1-Hydroxyethylidene-1 1-Diphosphonic Acid Testing

The principle of testing is to convert 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP) to ortho phosphorus. And then to measure phosphorous. The aim of the test is to detect the content of phosphorus (total phosphorus) in water. This testing is divided into two parts. They are inorganic phosphorus and organic phosphorus. The inorganic phosphorus portion may be composed […]
