Maintaining optimal pH is important for the removal of phosphorus from water. Phosphorus is most effectively removed at the neutral pH range, when the insoluble aluminum hydroxide is present. This hydroxide functions as a Lewis acid, [5] creating a flocculation environment similar to conventional wastewater treatment.
A common example is phosphoric acid, which additionally converts some iron oxide into an inert layer of ferric phosphate. [3] Most of the rust converters contain special additives. [4] They support the rust transformation and improve the wetting of the surface. Applied rust converter
Enhanced biological phosphorus removal (EBPR) is a sewage treatment configuration applied to activated sludge systems for the removal of phosphate. [ 1 ] The common element in EBPR implementations is the presence of an anaerobic tank ( nitrate and oxygen are absent) prior to the aeration tank.
Glyphosate (IUPAC name: N-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide and crop desiccant.It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSP).
The sites occupied solely by phosphate anions in stoichiometric hydroxyapatite, are occupied by phosphate or hydrogen phosphate, HPO 2− 4, anions. [14] These calcium-deficient phases can be prepared by precipitation from a mixture of calcium nitrate and diammonium phosphate with the desired Ca/P ratio, for example, to make a sample with a Ca ...
Glyphosate, part of the herbicide "Roundup", is a phosphonate. 2-aminoethylphosphonic acid: the first identified natural phosphonate. Phosphonates are one of the three sources of phosphate intake in biological cells. [citation needed] The other two are inorganic phosphate and organophosphates.
