  • What is the factor to convert from PO4 to PO4-P? - Hach
    To convert from units of orthophosphate (PO 4 3-) to orthophosphate as phosphorus (PO 4 -P), multiply the value by 0 3261 To convert from orthophosphate as phosphorus (PO 4 -P) to orthophosphate (PO 43-) divide the value by 0 3261 Many Hach spectophotometers and colorimeters give the option to change the chemical form of the reported value This number is a ratio of the atomic mass of the
  • Was ist der Faktor für die Umwandlung von PO4 in PO4-P? - Hach
    Zur Umrechnung von Einheiten von Orthophosphat (PO 43-) in Orthophosphat als Phosphor (PO 4 -P) wird der Wert mit dem Faktor 0,3261 multipliziert Um von Orthophosphat als Phosphor (PO 4 -P) in Orthophosphat (PO 43-) umzuwandeln, dividieren Sie den Wert durch 0,3261 Viele Hach-Spektrophotometer und Kolorimeter bieten die Möglichkeit, die chemische Form des angezeigten Wertes zu ändern
  • What is the conversion factor from orthophosphate (PO4) to . . . - Hach
    The conversion factor from orthophosphate (PO4) to phosphorus pentoxide (P2O5) is 0 7473 This conversion is based on the molar mass ratio for the two compounds
  • Quel est le facteur de conversion de PO4-P à PO4 - Hach
    De nombreux spectrophotomètres et colorimètres Hach offrent la possibilité de modifier la forme chimique de la valeur déclarée Puisque ce nombre est un ratio des masses atomiques des éléments dans la forme chimique, ce calcul ne modifie pas la concentration de phosphore dans l'échantillon ; il ne change que la valeur par rapport aux unités dans laquelle elle est exprimée Par
  • What’s your experience with redsea NO3;PO4-X (NOPOX)?
    So I’m considering trying redsea’s NOPOX to help keep phosphate and nitrates under better control so I can get better coral coloration and growth I know you must monitor levels carefully and use it with a protein skimmer in order for it to be effective I just want to know what other people have
  • ¿La conversión de una medición de PO4 a PO4-P determina la . . . - Hach
    La conversión de la forma química de los resultados de fósforo de PO4 a PO4-P no da la concentración total de fósforo El fósforo total es la suma de las formas orgánicas e inorgánicas de fosfato y requiere una digestión utilizando calor, ácido y persulfato para convertir fosfatos orgánicos y condensados en ortofosfato para su medición
  • Is Phosphate (PO4 3-) solube in water? - Chemistry Stack Exchange
    Josh~ Superphosphate is used instead of just phosphate because superphosphate is a compound whereas phosphate is an ion This means that phosphate must attach itself with a cation in order to give a
  • Phosphates Functional Group - Chemistry Stack Exchange
    In my text book it states that a phosphate group is considered to be $\ce {-OPO3^ {2-}}$ However, online it states that phosphate is $\ce {PO4^ {3-}}$ Why do these contradict? Am i confusing phosphat

  • Reading Salifert PO4 Test - Nano-Reef Community
    That would put something around 03 ppm PO4 to 5ppm NO3 at a good ratio As long as it looks closer to 03ppm than adjacent levels, it is good If you aren’t suddenly having issues from elevated PO4, which I’d imagine you would have less trouble differentiating colors from those levels, the exact reading isn’t critical
