Ethylenediaminetetraacetic acid (EDTA)
Ethylenediaminetetraacetic acid (EDTA) ndi organic pawiri ndi mankhwala chilinganizo C10H16N2O8. Ndi ufa woyera kutentha kutentha ndi kupanikizika. Ndi chinthu chomwe chimatha kuchitapo kanthu ndi Mg2+Chelating agent yomwe imaphatikiza ma ayoni achitsulo apakati monga Ca2+, Mn2+,ndi Fe2+.
EDTA ndi wothandizira wofunikira. EDTA ili ndi ntchito zosiyanasiyana ndipo ingagwiritsidwe ntchito ngati blekning ndi kukonza njira yopangira zinthu zowonongeka zamtundu, zopangira utoto, zowonjezera zodzikongoletsera, zotsitsimutsa, ndi zoyambitsa mphira za polymerization, EDTA ndi chinthu choyimira cha chelating agents. Itha kupanga zokhazikika zosungunuka m'madzi zokhala ndi zitsulo zamchere, zinthu zapadziko losowa, ndi zitsulo zosinthika. Kuphatikiza pa mchere wa sodium, palinso ammonium salt ndi mchere wosiyanasiyana monga chitsulo, magnesium, calcium, mkuwa, manganese, zinki, cobalt, aluminium, etc., aliyense ali ndi ntchito zosiyanasiyana.
Kuphatikiza apo, EDTA itha kugwiritsidwanso ntchito kutulutsa mwachangu zitsulo zowopsa za radioactive m'thupi la munthu ndikuchita gawo lochotsa poizoni. Ndiwothandiziranso madzi.
EDTA ndi chizindikiro chofunikira, koma imagwiritsidwa ntchito popanga zitsulo monga faifi tambala ndi mkuwa. Mukagwiritsidwa ntchito, iyenera kugwiritsidwa ntchito limodzi ndi ammonia kuti ikhale chizindikiro.
Pali mitundu yambiri ya EDTA, ndipo kampani yathu imapanga EDTA 2Na EDTA 4Na, EDTA CaNa2, EDTA KuNa2, EDTA FeNa, EDTA MgNa2, EDTA MnNa2, EDTA ZnNa2, NTA, NTA-3Na, etc.
EDTA 2Na: Dzina lonse ndi disodium ethylenediaminetetraacetate, yokhala ndi mankhwala C.10H14N2O8Na2• 2H2O. Amagwiritsidwa ntchito ngati zotsukira, zopangira utoto, zopangira fiber, zowonjezera zodzikongoletsera, zowonjezera chakudya, feteleza yaying'ono yaulimi, ndi ulimi wam'madzi.
EDTA 4Na: Dzina lonse ethylenediaminetetraacetic acid tetrasodium, mankhwala chilinganizo C10H12N2O8Na4.4H2O, ntchito monga zofewetsa madzi, kupanga mphira chothandizira, akiliriki polymerization kuthetsa wothandizira, kusindikiza ndi utoto wothandizira, detergent wothandizira, etc.
EDTA Kana2: Dzina lonse la calcium sodium ethylenediaminetetraacetate, mankhwala formula C10H12N2O8KaNa2• xH2O, yogwiritsidwa ntchito ngati cholekanitsa, ndi madzi osungunuka a chelating agent omwe amatha chelate multivalent iron ions. Kashiamu ndi chitsulo kusinthana kupanga chelates okhazikika.
EDTA KUNA2: Dzina lonse mkuwa sodium ethylenediaminetetraacetate, mankhwala chilinganizo C10H12N2O8KuNa2• 2H2O, copper sodium ethylenediaminetetraacetate ndi sungunuka mmadzi chelating agent, ndipo mkuwa ndi chelating agent.
EDTA FeNa: Dzina lonse la copper sodium ethylenediaminetetraacetate, chemical formula C10H12N2O8KuNa2• 2H2O, amagwiritsidwa ntchito ngati decolorizing pojambula. Amagwiritsidwa ntchito ngati chowonjezera m'mafakitale azakudya, ngati chowunikira muulimi, komanso ngati chothandizira pamakampani.
EDTA MgNa2: Dzina lonse ndi magnesium sodium ethylenediaminetetraacetate, yokhala ndi chilinganizo chamankhwala C10H12N2O8MgNa2 • 2H2O. Magnesium sodium ethylenediaminetetraacetate ndi madzi sungunuka chelating agent.
EDTA MnNa2, yomwe imadziwikanso kuti ethylenediaminetetraacetic acid manganese sodium, ili ndi chilinganizo cha mankhwala C10H12MnN2Na2O8. Amagwiritsidwa ntchito ngati chinthu chopangira feteleza wamasamba muulimi ndi ulimi wamaluwa, komanso chinthu chotsatira cha hydroponics.
EDTA ZnNa2: Dzina lonse: Zinc sodium ethylenediaminetetraacetate, chilinganizo cha mankhwala: C10H12N2O8ZnNa2• 2H2O, zinki sodium ethylenediaminetetraacetate ndi madzi sungunuka chelating agent, ndipo zinki ndi chelating agent.
NTA: Dzina lonse ndi triacetic acid, mankhwala opangidwa ndi C6H9NO6, yomwe ili yabwino kwambiri yokonza makina opanga utoto, imagwira ntchito yokhazikika pakupanga styrene, ndipo imakhala ngati chothandizira komanso chophatikizira popanga thovu la polyurethane.
NTA-3Na: Dzina lonse la trisodiumaminotriacetate, mankhwala formula C6H9NA3O6, amagwiritsidwa ntchito ngati chelating agent.
