Phosphate species
WebFeb 1, 2016 · 1. Introduction. Phosphorus is one of the essential elements for many living organisms. Dissolved phosphorus compounds in aqueous solution can be classified into three species types which are orthophosphate (PO 4 3-, ortho-P), polyphosphate (a chain link molecule of ortho-P such as P 3 O 10 5-, poly-P), and organic phosphorus which consists … WebPhosphate-containing species are in constant flux throughout the phosphorus cycle and accumulate within the cells of all living organisms. Cellular energy is primarily harvested …
