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 onye ọrụ aghụghọ dị mkpa. 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.
