Ethylenediaminetetraacetic acid (EDTA)
Ethylenediaminetetraacetic acid (EDTA) bụ ngwakọta organic nke nwere usoro kemịkalụ C10H16N2O8. Ọ bụ ntụ ntụ ọcha na ụlọ okpomọkụ na nrụgide. Ọ bụ ihe nwere ike meghachi omume na Mg2+Onye na-ahụ maka aghụghọ na-ejikọta ion ọla dị iche iche dị ka Ca2+, Mn2+, na Fe2+.
EDTA bụ ihe dị mkpa na-aghọ aghụghọ. EDTA nwere ọtụtụ ngwa ngwa ma enwere ike iji ya dị ka ịcha ọcha na idozi ihe ngwọta maka nhazi nke ihe ndị na-agba agba, ihe ndị na-esiji ákwà, ihe mgbakwunye ịchọ mma, stabilizers, na synthetic roba polymerization initiators, EDTA bụ ihe nnọchiteanya nke ndị na-emepụta ihe. Ọ nwere ike na-etolite ụlọ kwụsiri ike na mmiri-soluble nwere ọla alkali, ihe ụwa na-adịghị ahụkebe, na ọla mgbanwe. Na mgbakwunye na sodium salts, e nwekwara ammonium salts na dị iche iche nnu dị ka ígwè, magnesium, calcium, ọla kọpa, manganese, zinc, cobalt, aluminum, wdg, nke ọ bụla nwere dị iche iche ojiji.
Na mgbakwunye, EDTA nwekwara ike iji ngwa ngwa wepụ ọla redioaktivu na-emerụ ahụ n'ahụ mmadụ ma rụọ ọrụ na-emebi ihe. Ọ bụkwa onye na-ahụ maka ọgwụgwọ mmiri.
EDTA bụkwa ihe nrịbama dị mkpa, mana a na-eji ya titrate ọla dị ka nickel na ọla kọpa. Mgbe ejiri ya, a ga-eji ya na amonia mee ihe dị ka ihe ngosi.
Enwere ọtụtụ ụdị EDTA, ụlọ ọrụ anyị na-emepụta EDTA 2Na EDTA 4Na, EDTA CaNa.2, EDTA CuNa2, EDTA FeNa, EDTA MgNa2, EDTA MnNa2, EDTA ZnNa2, NTA, NTA-3Na, wdg.
EDTA 2Na: Aha zuru oke bụ disodium ethylenediaminetetraacetate, yana usoro kemịkalụ C.10H14N2O8Na2• 2H2O. A na-eji ya dị ka ncha, ihe enyemaka ịjiji, onye na-ahụ maka ọgwụgwọ eriri, ihe mgbakwunye ịchọ mma, mgbakwunye nri, obere fatịlaịza ugbo, na aquaculture mmiri.
EDTA 4Na: Aha zuru oke ethylenediaminetetraacetic acid tetrasodium, usoro kemịkalụ C10H12N2O8Na4.4H2O, eji dị ka ihe na-eme ka mmiri dị nro, ihe na-eme ka rọba sịntetik, onye na-ejedebe polymerization acrylic, onye na-ebi akwụkwọ na ịcha akwa, onye enyemaka ncha, wdg.
EDTA CaNa2Aha zuru oke calcium sodium ethylenediaminetetraacetate, usoro kemịkalụ C10H12N2O8CaNa2• xH2O, eji dị ka ihe na-ekewapụ, bụ ihe na-agbaze mmiri nke nwere ike chelate ion ígwè multivalent. Calcium na ígwè na-agbanwe iji mepụta chelates kwụsiri ike karị.
EDTA CuNa2Aha zuru oke ọla kọpa sodium ethylenediaminetetraacetate, usoro kemịkalụ C10H12N2O8KuNa2• 2H2O, ọla kọpa sodium ethylenediaminetetraacetate bụ mmiri na-agbaze mmiri, na ọla kọpa bụ ihe na-eme ka mmiri na-agbaze.
EDTA FeNa: Aha zuru oke ọla kọpa sodium ethylenediaminetetraacetate, usoro kemịkalụ C10H12N2O8KuNa2• 2H2O, eji dị ka ihe na-eme ka agba na-ese foto. A na-eji ya dị ka ihe mgbakwunye na ụlọ ọrụ nri, dị ka ihe na-achọpụta na ọrụ ugbo, yana dịka ihe na-akpali akpali na ụlọ ọrụ.
EDTA MgNa2Aha zuru oke bụ magnesium sodium ethylenediaminetetraacetate, nke nwere usoro kemịkalụ C10H12N2O8MgNa2 • 2H2O. Magnesium sodium ethylenediaminetetraacetate bụ ihe na-agbaze mmiri.
EDTA MnNa2, nke a makwaara dị ka ethylenediaminetetraacetic acid manganese sodium, nwere usoro kemịkalụ C10H12MnN2Na2O8. A na-eji ya dị ka ihe mmewere maka fatịlaịza foliar na ọrụ ugbo na ihe ọkụkụ, yana ihe nchọta maka hydroponics.
EDTA ZNNa2Aha zuru oke: Zinc sodium ethylenediaminetetraacetate, usoro kemịkalụ: C10H12N2O8ZnNa2• 2H2O, zinc sodium ethylenediaminetetraacetate bụ ihe na-eme ka mmiri na-agbaze mmiri, yana zinc bụ ihe na-eme ka mmadụ chelate.
NTA: Aha zuru oke bụ triacetic acid, usoro kemịkal bụ C6H9NO6, nke bụ ihe na-edozi ahụ nke ọma na ụlọ ọrụ ịcha akwa, na-arụ ọrụ na-edozi ahụ na mmepụta nke styrene, ma na-eme ihe dị ka ihe na-eme ka ọ bụrụ ihe mgbagwoju anya na mmepụta nke ụfụfụ polyurethane.
NTA-3Na: aha zuru oke trisodiumaminotriacetate, usoro kemịkalụ C6H9Nna3O6, ejiri mee ihe dị ka onye na-eme aghụghọ.
