Ethylenediaminetetraacetic acid (EDTA)
Ethylenediaminetetraacetic acid (EDTA) waa unug dabiici ah oo leh qaacidada kiimikada C10H16N2O8. Waa budo cad heerkulka qolka iyo cadaadiska. Waa walax ka falcelin karta Mg2+Wakaaliyaha chelating ee isku dara aions biraha kala duwan sida Ca2+, Mn2+iyo Fe2+.
EDTA waa wakiilka khiyaamada muhiimka ah. EDTA waxay leedahay codsiyo badan oo kala duwan waxaana loo isticmaali karaa sidii bleaching iyo xallinta hagaajinta qalabka xasaasiga ah ee midabka, kaaliyeyaasha midabaynta, waxyaabaha lagu daro qurxinta, xasiliyeyaasha, iyo curiyeyaasha caagga synthetic polymerization, EDTA waa walax wakiil ka ah wakiilada chelating. Waxay samayn kartaa dhismayaal biyo-milmi leh oo deggan oo leh biraha alkali, curiyeyaasha dhulka naadir, iyo biraha kala-guurka. Marka laga soo tago cusbada Soodiyamka, waxa kale oo jira cusbada ammonium-ka iyo milixyada kala duwan sida iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminium, iwm, kuwaas oo mid walba leh adeegsi kala duwan.
Intaa waxaa dheer, EDTA sidoo kale waxaa loo isticmaali karaa in si dhakhso ah looga saaro biraha shucaaca ee waxyeelada leh ee jirka bini'aadamka oo ay ka ciyaaraan door sun-saarid ah. Sidoo kale waa wakiilka biyaha lagu daweeyo.
EDTA sidoo kale waa tilmaame muhiim ah, laakiin waxaa loo isticmaalaa in lagu titrate biraha sida nikkel iyo copper. Marka la isticmaalo, waa in lala isticmaalo ammonia si ay u noqoto tilmaame.
Waxaa jira noocyo badan oo EDTA ah, shirkadeenana waxay soo saartaa EDTA 2Na EDTA 4Na, EDTA CaNa2, EDTA CuNa2, EDTA FeNa, EDTA MgNa2, EDTA MnNa2, EDTA ZnNa2, NTA, NTA-3Na, iwm.
EDTA 2Na: Magaca buuxa waa disodium ethylenediaminetetraacetate, oo leh caanaha kiimikada C10H14N2O8Na2• 2H2O. Waxa loo isticmaalaa saabuun ahaan, gargaar midabaynta, wakiilka daawaynta faybarka, waxyaabaha la isku qurxiyo, lagu daro cuntada, bacriminta yar yar ee beeraha, iyo aquaculture badda.
EDTA 4Na: Magaca buuxa ethylenediaminetetraacetic acid tetrasodium, qaacidada kiimikada C10H12N2O8Na4.4H2O, loo isticmaalo jilciye biyaha, kicinta caagga synthetic, wakiilka joojinta polymerization acrylic, kaaliyaha daabacaadda iyo midabaynta, caawiyaha saabuunta, iwm.
EDTA CaNa2Magaca buuxa ee calcium sodium ethylenediaminetetraacetate, caanaha kiimikada C10H12N2O8CaNa2• xH2O, oo loo isticmaalo kala soocida ahaan, waa walax biyo-milmi kara oo kicin kara ion birta kala duwan. Kaalshiyamka iyo birta waxay isweydaarsadaan si ay u sameeyaan chelates xasilloon.
EDTA CuNa2Magaca buuxa ee copper sodium ethylenediaminetetraacetate, qaacidada kiimikada C10H12N2O8CuNa2• 2H2O, naxaasta sodium ethylenediaminetetraacetate waa wakiil biyo-milmi kara, iyo naxaasku waa wakiilka chelating.
EDTA FeNa: Magaca buuxa ee naxaasta sodium ethylenediaminetetraacetate, caanaha kiimikada C10H12N2O8CuNa2• 2H2O, loo isticmaalo sidii wakiilka midabaynta sawirka. Loo isticmaalo wax lagu daro warshadaha cuntada, sida cunsur raad ku leh beeraha, iyo kicinta warshadaha.
EDTA MgNa2Magaca buuxa waa magnesium sodium ethylenediaminetetraacetate, oo leh caanaha kiimikada C10H12N2O8MgNa2 • 2H2O. Magnesium sodium ethylenediaminetetraacetate waa walax biyo-milmi leh.
EDTA MnNa2, oo sidoo kale loo yaqaano ethylenediaminetetraacetic acid manganese sodium, ayaa leh caanaha kiimikada C10H12MnN2Na2O8. Waxaa loo isticmaalaa sidii curiye loogu talagalay bacriminta foliar ee beeraha iyo dhirta, iyo sidoo kale curiyaha raad ee hydroponics.
EDTA ZnNa2Magaca buuxa: Zinc sodium ethylenediaminetetraacetate, caanaha kiimikada: C10H12N2O8ZnNa2• 2H2O, Zinc sodium ethylenediaminetetraacetate waa wakiilka chelating ee biyaha ku milma, iyo zinc waa wakiilka chelating.
NTA: Magaca buuxa waa triacetic acid, qaacidada kiimikada waa C6H9NO6, taas oo ah wakiilka saxda ah ee saxda ah ee warshadaha dheeha, waxay door ka ciyaareysaa doorka xasilinta wax soo saarka styrene, waxayna u shaqeysaa sida kicinta iyo walaxda isku dhafan ee soo saarista xumbo polyurethane.
NTA-3Na: Magaca buuxa ee trisodiumaminotriacetate, qaacidada kiimikada C6H9NNa3O6, loo isticmaalo sidii wakiilka qayilaada.
