EDTA Disodium (EDTA-2Na) |139-33-3
Sharaxaada Alaabta
Ethylenediaminetetraacetic acid, oo si weyn loo soo gaabiyo EDTA, waa aminopolycarboxylic acid iyo mid aan midab lahayn, biyo-milmi leh.Saldhigeeda conjugate waxaa lagu magacaabaa ethylenediaminetetraacetate.Waxaa si weyn loo isticmaalaa in lagu milo miisaanka limescale.Faa'iidadeeda waxay soo baxdaa sababtoo ah doorkeeda sida hexadentate ("lix-ilig") iyo wakiilka chelating, ie awoodda ay u leedahay inay "sequester" ion birta ah sida Ca2+ iyo Fe3+.Ka dib marka lagu xidho EDTA, ions biraha ayaa ku sii jiraya xalka laakiin waxay muujinayaan falcelin yar.EDTA waxaa loo soo saaraa sida milixyo kala duwan, gaar ahaan disodium EDTA iyo calcium disodium EDTA.
