Popular questions
How are sodium phosphates made?
They’re produced by neutralizing food‑grade phosphoric acid with sodium hydroxide, carbonate, or bicarbonate to the desired ratio to yield mono-, di-, or trisodium phosphate, then crystallizing (often as hydrates); condensed polyphosphates are made by dehydrating/condensing orthophosphates at elevated temperatures.
How do saline enema sodium phosphates work?
They act as hyperosmotic salts that draw water into the colon, increasing volume and stimulating peristalsis to trigger a bowel movement; improper use can cause fluid and electrolyte imbalances, so they should be used only as directed.
How does sodium aluminate react with phosphates?
In water, sodium aluminate hydrolyzes to Al(OH)3, which binds phosphate and precipitates it as insoluble aluminum phosphate (AlPO4), especially near neutral pH—this is the basis for phosphate removal in water treatment.
How many meq of sodium does sodium phosphates have?
It depends on the specific salt and hydration: anhydrous NaH2PO4 ≈8.3 mEq Na per gram, Na2HPO4 ≈14.1 mEq/g, and Na3PO4 ≈18.3 mEq/g (hydrates contain less per gram); a typical adult sodium phosphate enema contains about 190 mEq of sodium.
How many sodium phosphates are there?
There are three main orthophosphate salts used in foods—monosodium, disodium, and trisodium phosphate—listed as E339(i–iii), plus various hydrates and condensed (polyphosphate) forms.
Girlsdoporn e452 who is she?
That appears unrelated to the food additive E452; E452 refers to polyphosphates, synthetic phosphate salts used in foods as emulsifiers, stabilizers, humectants, and sequestrants.
How does polyphosphates reduce affinity of hemoglobin for oxygen?
Inorganic polyphosphate can bind to positively charged sites on deoxyhemoglobin and stabilize the low‑affinity T-state, shifting the oxygen dissociation curve to the right and lowering O2 affinity. This is a biochemical interaction and not a typical food-use effect of E452.
How many states use polyphosphates?
There’s no official tally; polyphosphates are used by many water utilities across numerous U.S. states and worldwide for iron/manganese sequestration and scale/corrosion control, depending on local water chemistry.
How many states use polyphosphates to treat water?
No centralized count exists, but hundreds of U.S. community water systems in dozens of states use phosphate-based treatments (often polyphosphates or poly/ortho blends) for metal sequestration and corrosion control. Usage changes over time with source water and regulations.
How to remove polyphosphates from drinking water?
Effective options include reverse osmosis or nanofiltration, and strong‑base anion exchange; utilities may also use coagulation/precipitation with iron or alum followed by filtration. Polyphosphates hydrolyze to orthophosphate over time, which the same processes remove; activated carbon and boiling are generally ineffective.
