EDTA ke moemeli oa bohlokoa oa chelating. EDTA e na le mefuta e mengata ea likopo 'me e ka sebelisoa e le bleaching le tharollo ea ho lokisa bakeng sa ho sebetsana le lisebelisoa tse nang le mebala, lithuso tsa ho daea, li-consmetic additives, stabilizers, le li-initiators tsa polymerization tsa rabara, EDTA ke ntho e emelang li-chelating agents. E ka etsa li-complexes tse tsitsitseng tse qhibilihang ka metsing tse nang le litšepe tsa alkali, likarolo tse sa tloaelehang tsa lefatše, le litšepe tsa phetoho. Ntle le matsoai a sodium, ho boetse ho na le letsoai la ammonium le matsoai a sa tšoaneng a kang tšepe, magnesium, calcium, koporo, manganese, zinki, cobalt, aluminium, joalo-joalo, e 'ngoe le e' ngoe e nang le litšebeliso tse fapaneng.
Ntle le moo, EDTA e ka boela ea sebelisoa ho ntša kapele litšepe tse kotsi tse tsoang 'meleng oa motho le ho bapala karolo ea ho ntša chefo. Hape ke moemeli oa ho hloekisa metsi.
EDTA e boetse ke sesupo sa bohlokoa, empa e sebelisoa ho titrate litšepe tse kang nickel le koporo. Ha e sebelisoa, e tlameha ho sebelisoa hammoho le ammonia ho sebetsa joalo ka sesupo.
Ho na le mefuta e mengata ea EDTA, 'me k'hamphani ea rona e hlahisa EDTA 2Na EDTA 4Na, EDTA CaNa.2, EDTA CuNa2, EDTA FeNa, EDTA MgNa2, EDTA MnNa2, EDTA ZnNa2, NTA, NTA-3Na, joalo-joalo.
EDTA 2Na: Lebitso le felletseng ke disodium ethylenediaminetetraacetate, e nang le foromo ea lik'hemik'hale C.10H14N2O8Na2• 2H2O. E sebelisoa e le sesepa, thuso ea ho daea, fiber treatment agent, cosmetic additive, food additive, temo e nyenyane ea manyolo, le marine aquaculture.
EDTA 4Na: Lebitso le felletseng ethylenediaminetetraacetic acid tetrasodium, foromo ea lik'hemik'hale C10H12N2O8Na4.4H2O, e sebelisoang e le sesebelisoa sa ho nolofatsa metsi, sesebelisoa sa rabara sa maiketsetso, moemeli oa ho felisa acrylic polymerization, motlatsi oa khatiso le ho daea, mothusi oa sesepa, joalo-joalo.
EDTA CaNa2Lebitso le felletseng la calcium sodium ethylenediaminetetraacetate, foromo ea lik'hemik'hale C10H12N2O8KaNa2• xH2O, e sebelisoang e le moemeli oa ho arola, ke sesebelisoa sa chelating se nang le metsi se khonang ho chelate li-ion tsa tšepe tse ngata. Phapanyetsano ea calcium le tšepe ho theha chelate e tsitsitseng haholoanyane.
EDTA CuNa2: Lebitso le felletseng la koporo sodium ethylenediaminetetraacetate, foromo ea lik'hemik'hale C10H12N2O8CuNa2• 2H2O, copper sodium ethylenediaminetetraacetate ke ntho e qhibilihang ka metsing, 'me koporo ke ntho e chelating.
EDTA FeNa: Lebitso le felletseng la koporo sodium ethylenediaminetetraacetate, foromo ea lik'hemik'hale C10H12N2O8CuNa2• 2H2O, e sebelisoang joalo ka ntho e senyang mebala ho nka lifoto. E sebelisoa e le tlatsetso indastering ea lijo, joalo ka karolo ea morao-rao temong, hape e le sesosa sa indasteri.
EDTA MgNa2Lebitso le felletseng ke magnesium sodium ethylenediaminetetraacetate, e nang le foromo ea lik'hemik'hale C10H12N2O8MgNa2 • 2H2O. Magnesium sodium ethylenediaminetetraacetate ke motsoako oa chelating o qhibilihang ka metsing.
