Determining inorganic and organic phosphorus

The original version of this chapter was revised. The correction to this chapter is available at https://doi.org/10.1007/7651_2019_253Phosphorus (P) is a macronutrient for all microalgal species, and the main form of uptake is as orthophosphate (PO4). In this chapter we present a colorimetric method for determining the PO4 concentration and dissolved organic phosphorus (DOP) based on total phosphorus (TP) measurements. We also describe a method for determining particulate organic phosphorus (POP) based on the same principles.Peer reviewe
