WebTo measure condensed phosphates, it is first necessary to transform them into orthophosphate using sulfuric acid and heat, digesting the sample at 150°C for 30 minutes. This is called “acid hydrolyzable phosphate” since the condensed phosphates are hydrolyzed into orthophosphate.

WebTherefore, an orthophosphate test will likely measure a small amount of condensed phosphates and an acid-hydrolyzable test will measure a small amount of organic phosphates. Phosphorus relationships are …
