Introduction Nitrogen and phosphorus are essential nutrients for all living organisms that are required to support the growth of plants, feed animals, and ultimately provide adequate nutrition for an expanding global population. WebLe phosphore, sous forme inorganique et organique, est transformé à chaud (121 °C) et sous pression en orthophosphate (PO 4 3- ) en présence de persulfate de potassium et d’acide sulfurique. L’orthophosphate réagit avec le molybdate dammonium en milieu acide pour former l’ ’acide phosphomolybdique.
