        Phosphorus

         

        Phosphorus

        Common in natural systems, such as lakes, oceans, and soil, phosphorus is an essential element for plant and animal growth. However, when present in large concentrations, phosphorus can cause excessive microorganism and algae growth. For this reason many wastewater treatment plants monitor the total phosphorus that is discharged. It is one of the primary nutrients that is removed chemically or biologically.

        For hobbyists with saltwater or freshwater aquaria, a high amount of phosphorus can be problematic to fish, plants, and coral.

        The amount of phosphorus can be expressed in two different ways:

         

        • Phosphate (PO43-) also known as orthophosphate, or as
        • Phosphorus (P) also known as orthophosphate as phosphorus (PO4-P).

         

        Orthophosphate is a molecule with a phosphorus atom surrounded by four oxygen atoms, and a negative three charge. Phosphorus or orthophosphate, is a measure of the amount of orthophosphate (PO43-) molecules in a sample. While phosphorus or orthophosphate as phosphorus (PO4-P), is a measure of the amount of phosphorus (P) ions in a sample. This means that when measuring phosphorus, the four oxygen atoms bound to the phosphorus atom are included in the measurement. However, it is possible to easily convert between the two measurements with simple multiplication or division. To convert a result from phosphorus (P) to phosphorus (PO43-) you simply need to multiply by 3.06. Conversely, to convert from phosphorus to phosphorus you just need to divide by 3.06. The reason this works is because the orthophosphate molecule (PO43-) is approximately 3.06 times heavier than the phosphorus atom.

        Hanna offers a variety of chemical based methods to measure phosphorus. These include reactive, acid hydrolyzable, and total phosphorus.

         

        Reactive Phosphorus

        Reactive phosphorus is the simplest form, known as phosphate or orthophosphate. It is considered reactive since it easily reacts or bonds with cations. Orthophosphate is commonly added to water to inhibit corrosion of pipes in the distribution of water.

         

        Acid Hydrolyzable Phosphorus

        Acid Hydrolyzable Phosphorus also known, as condensed phosphate is a complex form of orthophosphate that are bound together. These forms include polyphosphate, pyrophosphate, and metaphosphate, which are used in boiler and cooling tower water treatment for corrosion inhibition of pipes.

         

        Total Phosphorus

        Total phosphorus (Total P) is the sum of all phosphorus including inorganic (orthophosphate and acid hydrolyzable) and organic matter such as the phosphorus found in living matter (i.e.ATP/ADP). In order to measure the organic phosphorus, the sample needs to be digested with an acid and heat in order to breakdown the organically bound phosphorus to the simplest form, orthophosphate.

        Available technologies to measuring phosphorus include spectrophotometers, benchtop and portable photometers, Checker HC and chemical test kits.
