We have an insert on this page that seems to weaken the notion that EDTA bonds to divalent ions. Is one of us going to have to look up association constants for this compound in order to determine specificity? The way the text reads, you would think you could use EDTA to scavenge things like octavalent osmium. Dwmyers 16:21, 20 Sep 2003 (UTC)
- It was me who added "trivalent", for I had in mind that Iron(III)-EDTA is more stable than Iron(II)-EDTA... Actually I'm not sure where to draw the line; e.g. I never heard of any EDTA-Complex with a more than trivalent metal, but can't exclude the possibility... Maybe you'll just delete the "etc."?

[edit] tetrasodium edta
Ever since I was old enough to read (which was a pretty young age), I've seen tetrasodium edta in a lot of crap. Is it easily synthesized and not toxic enough a chelating agent in its produced concentrations to worry? In sum, WTF? It's not like I'm worried about additives, but they better at least have a real purpose--how does it preserve foods, and why do we use it instead of something else?
-Todan
EDTA and its derivatives such as Disodium or Tetrasodium are not a preservative per se. They aid preservation by sequestering metal ions in solutions, and impairing bacterial growth effectively "starving" the bugs of neutrients. They make the preservative added more effective. Pedantic I know

[edit] EDTA causes lead to be relocated to the brain?
In the Uses section, it is stated, "Note that EDTA causes lead to be relocated in the human body into the brain so its use as an antidote has been discontinued." I have never read this, is there a citation of any sort? George100 16:41, 1 June 2006 (UTC)
[edit] blade 2
Can someone clean-up the "blade 2" reference in the trivia section (if it's even necessary to have this information in the acticle)? I know there's a movie, but isn't there a video game and also a TV series. Should it be "blade 2" or "Blade 2"? Also, a link to the movie/game/TV series would be useful. I've never seen that movie or the TV show or played the game otherwise I would change it myself. dq 21:53, 12 September 2006 (UTC)
[edit] Recycling Lead Acid Batteries
The main article is seeking a citation for this - There is a good page on it at http://www.mztech.fsnet.co.uk/electrics/elc_edta.html if that helps. I have no idea how to add citations so somebody else may want to alter it.

EDTA is also used in some fertilizers, to keep iron in solution and available for plant uptake.
[edit] IUPAC nomenclature
If anyone is interested, the IUPAC nomenclature should be 2-(carboxy(2-(carboxy(1-hydroxy-2-oxoethyl)amino)ethyl)amino)acetic acid, though I might be wrong. Just incase anyone is interested.

Is EDTA vegan? 66.30.67.235 13:41, 5 July 2007 (UTC)
- As a synthetic molecule that doesn't occur in nature, EDTA is vegan, as are most preservative ingredients. 130.126.229.231 22:42, 27 July 2007 (UTC)
[edit] Why is relevant info regaurding the toxicity of this compound being removed from this page?
User Edgar removed my findings on EDTA that were obtained from US government servers and are publicly available under the Freedom of Information Act. This information was removed from the page citing a copyright violation? How does information reposted from a public government server constitute a copyright violation. This seems like a deliberate attempt to suppress information regarding this compound and its increasing use in a variety of food products as a preservative. —Preceding unsigned comment added by Ianocmedia (talk • contribs) 18:26, 3 December 2007 (UTC)

[edit] Two different drugs called EDTA
Check out this FDA article. According to them, the chelator for lead is "Calcium Disodium Versenate" with the chemical name of edetate calcium disodium. The other is simply edetate disodium, marketed as Endrate. The FDA says that the former, edetate disodium, has caused 11 deaths. I think we need to make clear the distinction on this page, to clarify and help avoid future deaths. ImpIn | (t - c) 08:46, 6 June 2008 (UTC)
