Mathematical Modeling of Phosphorus Transformation in the Lake Balaton Ecosystem [PDF]
, 1980 An ecological model of the phosphorus system is described. This model includes five phosphorus forms found in water, namely: phytoplankton-P, bacterial-P, dissolved inorganic-P, dissolved organic-P and nonliving particulate-P, and also three phosphorus ...

Multi-pumping flow system for the determination of dissolved orthophosphate and dissolved organic phosphorus in wastewater samples [PDF]
Analytica Chimica Acta, 2006 A multi-pumping flow system (MPFS) for the spectrophotometric determination of dissolved orthophosphate and dissolved organic phosphorus in wastewater samples is proposed. The determination of orthophosphate is based on the vanadomolybdate method. In-line ultraviolet photo-oxidation is employed to mineralise organic phosphorus to orthophosphate prior ...

Global Biogeochemical Cycles, 2022 AbstractMarine dissolved organic phosphorus (DOP) serves as an organic nutrient to marine autotrophs, sustaining a portion of annual net community production (ANCP). Numerical models of ocean circulation and biogeochemistry have diagnosed the magnitude of this process at regional to global scales but have thus far been validated against DOP ...
