Ethylenediaminetetraacetic acid (EDTA)

I-Ethylenediaminetetraacetic acid (EDTA)

I-Ethylenediaminetetraacetic acid (EDTA) iyinhlanganisela ye-organic enefomula yamakhemikhali C₁₀H₁₆N₂O₈. Kuyimpushana emhlophe ekamelweni lokushisa nokucindezela. Kuyinto engasabela nge-Mg²⁺I-ejenti ye-chelating ehlanganisa ama-ion ensimbi ahlukene njenge-Ca²⁺, Mn²⁺, futhi Fe²⁺.

I-EDTA iyi-ejenti yokuchela ebalulekile. I-EDTA inezinhlobonhlobo zezinhlelo zokusebenza futhi ingasetshenziswa njengesixazululo sokuhlanza nokulungisa ukulungisa izinto ezizwelayo ngombala, izinsiza zokudaya, izithasiselo zezimonyo, iziqinisi, neziqalisi ze-polymerization zenjoloba zokwenziwa, i-EDTA iyinto emele ama-chelating agents. Ingenza izakhiwo ezinzile ezincibilika emanzini ngezinsimbi ze-alkali, izakhi zomhlaba ezingavamile, nezinsimbi eziguqukayo. Ngaphezu kosawoti we-sodium, kukhona nosawoti we-ammonium nosawoti ohlukahlukene njengensimbi, i-magnesium, i-calcium, ithusi, i-manganese, i-zinc, i-cobalt, i-aluminium, njll.

Ngaphezu kwalokho, i-EDTA ingasetshenziswa futhi ukukhipha ngokushesha izinsimbi eziyingozi ezikhipha imisebe emzimbeni womuntu futhi idlale indima ekhipha ubuthi. Iphinde ibe i-ejenti yokuhlanza amanzi.

I-EDTA nayo iyinkomba ebalulekile, kodwa isetshenziselwa ukulinganisa izinsimbi ezifana ne-nickel nethusi. Lapho isetshenziswa, kufanele isetshenziswe kanye ne-ammonia ukuze isebenze njengenkomba.

Kunezinhlobo eziningi ze-EDTA, futhi inkampani yethu ikhiqiza i-EDTA 2Na EDTA 4Na, EDTA CaNa₂, EDTA CuNa₂, EDTA FeNa, EDTA MgNa₂, EDTA MnNa₂, EDTA ZnNa₂, NTA, NTA-3Na, njll.

I-EDTA 2Na I-EDTA FeNa

EDTA 2Na: Igama eligcwele yi-disodium ethylenediaminetetraacetate, enefomula yamakhemikhali C₁₀H₁₄N₂O₈Na₂• 2H₂O. Isetshenziswa njengesihlanzi, insiza yokudaya, i-ejenti yokwelapha ifayibha, isithako sezimonyo, isithasiselo sokudla, umanyolo omncane wezolimo, kanye ne-marine aquaculture.

EDTA 4Na: Igama eligcwele i-ethylenediaminetetraacetic acid tetrasodium, ifomula yamakhemikhali C₁₀H₁₂N₂O₈Na₄.4H₂O, esetshenziswa njengesithambisi samanzi, i-synthetic rubber catalyst, i-acrylic polymerization termination agent, umsizi wokuphrinta nokudaya, umsizi wokuhlanza, njll.

I-EDTA CaNa₂Igama eligcwele i-calcium sodium ethylenediaminetetraacetate, ifomula yamakhemikhali C₁₀H₁₂N₂O₈I-CaNa₂• xH₂I-O, esetshenziswa njenge-ejenti ehlukanisayo, iyi-ejenti e-chelating encibilika emanzini ekwazi ukucwenga ama-ion ensimbi amaningi. I-calcium ne-iron exchange ukuze kwakheke ama-chelates azinzile.

EDTA CuNa₂: Igama eligcwele i-copper sodium ethylenediaminetetraacetate, ifomula yamakhemikhali C₁₀H₁₂N₂O₈KuNa₂• 2H₂O, i-copper sodium ethylenediaminetetraacetate iyi-ejenti encibilikayo encibilika emanzini, futhi ithusi i-chelating agent.

I-EDTA FeNa: Igama eligcwele i-copper sodium ethylenediaminetetraacetate, ifomula yamakhemikhali C₁₀H₁₂N₂O₈KuNa₂• 2H₂O, esetshenziswa njenge-ejenti esusa umbala ezithombeni. Isetshenziswa njengesengezo embonini yokudla, njenge-trace element kwezolimo, nanjenge-catalyst embonini.

I-EDTA MgNa₂: Igama eligcwele i-magnesium sodium ethylenediaminetetraacetate, ne-chemical formula C₁₀H₁₂N₂O₈MgNa2 • 2H₂I-O. I-Magnesium sodium ethylenediaminetetraacetate iyi-ejenti ye-chelating encibilika emanzini.

EDTA MnNa₂, eyaziwa nangokuthi i-ethylenediaminetetraacetic acid manganese sodium, inefomula yamakhemikhali C₁₀H₁₂MnN₂Na₂O₈. Isetshenziswa njengesakhi sokuvundiswa kwe-foliar kwezolimo kanye ne-horticulture, kanye ne-trace element ye-hydroponics.

EDTA ZnNa₂: Igama eligcwele: I-Zinc sodium ethylenediaminetetraacetate, ifomula yamakhemikhali: C₁₀H₁₂N₂O₈ZnNa₂• 2H₂O, i-zinc sodium ethylenediaminetetraacetate iyi-ejenti encibilikayo encibilika emanzini, futhi i-zinc i-chelating.

I-NTA: Igama eligcwele i-triacetic acid, ifomula yamakhemikhali ngu-C₆H₉NO₆, okuyi-ejenti yokulungisa kahle embonini kadayi, idlala indima yokuzinza ekukhiqizeni i-styrene, futhi isebenza njenge-catalyst ne-ejenti eyinkimbinkimbi ekukhiqizeni i-polyurethane foam.

I-NTA-3Na: Igama eligcwele i-trisodiumaminotriacetate, ifomula yamakhemikhali C₆H₉NNA₃O₆, esetshenziswa njenge-ejenti e-chelating.
