Phosphorus (P) is a macronutrient for all microalgal species, and the main form of uptake is orthophosphate (PO). In this chapter we present a colorimetric method for determining the PO 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.
磷（P）是所有微藻物种的常量营养素，其主要吸收形式是正磷酸盐（PO）。在本章中，我们介绍一种基于总磷（TP）测量来测定PO浓度和溶解有机磷（DOP）的比色法。我们还描述了一种基于相同原理测定颗粒有机磷（POP）的方法。
