How can polyphosphates concentrations be determined?
Summary
Polyphosphates
Answer
To measure polyphosphates, an acid hydrolyzable phosphorous test such as 8180 must be run in addition to an orthophosphate test such as 8040. The polyphosphate is the difference between the acid hydrolyzable result and orthophosphate result.
