Abstract:
In measuring phosphoric acid by the use of an enzyme cycling system using a dehydrogenase together with a thio-NADP, a thio-NAD, a reduced thio-NADP or a reduced thio-NAD as a coenzyme, phosphoric acid is measurable in a wide concentration range from a low concentration to a high concentration by measuring phosphoric acid after previous removal of free phosphoric acid in reagent components for the measurement.
