Inorganic phosphate is the bioavailable dissolved form of phosphorus.

Principle:

Filtered water sample is allowed to react with a mixed reagent of molybdate, ascorbic acid, and trivalent antimony. The molybdic acid formed is converted by the reducing agent to a blue-coloured complex which is spectrophotometrically measured at 882nm. APHA(2017,ISBN:9780875532875).
