What is the difference between phosphates and phosphonates?
What is the difference between phosphates and phosphonates?
Phosphonates are generally capable of offering the same level of scale control as phosphates but can be included in formulations at concentrations one order of magnitude lower than phosphates. Although not readily biodegradable, phosphonates are not immune to photodegradation, hydrolysis or biodegradation over time.
What is the difference between phosphate and orthophosphate?
They are salts or esters of phosphoric acid. Orthophosphate is the simplest among other phosphates. The main difference between phosphate and orthophosphate is that phosphate is any compound composed of phosphate units whereas orthophosphate is composed of one phosphate unit.
How do you test for phosphates?
A small amount of the sample is acidified with concentrated nitric acid, to which a little ammonium molybdate is added. The presence of phosphate ions is indicated by the formation of a bright yellow precipitate layer of ammonium phosphomolybdate. The appearance of the precipitate can be facilitated by gentle heating.
What is the difference between phosphate and phosphorus?
Phosphorus is a multi-valent nonmetal chemical element of the VA group. Phosphate is a chemical derivative of the phosphoric acid, containing the phosphate ion (PO3−4). The symbol of phosphorus is P. The chemical formula of the phosphate ion is PO.
Is non-bio better for environment?
Is non-bio better for the environment? Not necessarily, as many non-bios still contain non-biodegradable surfactants, phosphates and other chemicals that aren’t exactly eco-friendly. The ones that we sell, however, have been specially formulated to be kinder to the planet.
Is non-bio a color?
Is Non-Bio Better for Colours? Yes. The enzymes and bleach in biological detergents cause colour fading faster. Some non-biological detergents still contain bleach so there may still be fading, but not as fast as an enzyme cleaner.
How to test for phosphonates in cooling water?
There are two fundamental approaches to testing for phosphonates in cooling water. Each based on the reaction between a metal and a complexing agent (phosphate or phosphonate). Both reactions are accompanied by the development of a distinguishable color, measurable either by a comparator, colorimeter, photo spectrometer or by titration.
How do you account for orthophosphate in phosphonate analysis?
If an undigested blank has been run, the orthophosphate present in raw water or as impurities in the phosphonate will have been accounted for. A figure for phosphonate results from the subtraction of the original orthophosphate from total phosphate. No significant hydrolysis or degradation of polyphosphates should occur.
What is the drop-count titration test for phosphonate?
Taylor offers two drop-count titration tests for phosphonate as shown in the chart below. Both kits employ the thorium nitrate method, but one uses xylenol orange (XO) as the phosphonate indicator and the other uses chrome azurol S (CAS).
How do you test for phosphorus in organic chemistry?
Orthophosphate, polyphosphate and organic phosphorus values are determined by running all three of the following tests, while only two are needed if the species of inorganic phosphate is not of interest or if phosphonate levels alone are required (Hydrolyzable plus either UV Test or Persulfate test).
