Ethylenediaminetetraacetic acid (EDTA)
Ethylenediaminetetraacetic acid (EDTA) ndi mankhwala achilengedwe okhala ndi formula ya mankhwala C10H16N2O8Ndi ufa woyera pa kutentha kwa chipinda ndi kupanikizika. Ndi chinthu chomwe chingagwirizane ndi Mg2+Chothandizira chelating chomwe chimaphatikiza ma ayoni achitsulo a divalent monga Ca2+, Mn2+ndi Fe2+.
EDTA ndi chinthu chofunikira kwambiri choyeretsera. EDTA ili ndi ntchito zambiri ndipo ingagwiritsidwe ntchito ngati njira yoyeretsera ndi kukonza zinthu zomwe zimakhala ndi utoto, zinthu zothandizira utoto, zowonjezera zokongoletsa, zokhazikika, ndi zoyambitsa kupanga polymerization ya rabara, EDTA ndi chinthu choyimira zinthu zoyeretsera. Imatha kupanga zinthu zosungunuka m'madzi zokhazikika ndi zitsulo za alkali, zinthu zapadziko lapansi zosowa, ndi zitsulo zosinthira. Kuphatikiza pa mchere wa sodium, palinso mchere wa ammonium ndi mchere wosiyanasiyana monga chitsulo, magnesium, calcium, copper, manganese, zinc, cobalt, aluminiyamu, ndi zina zotero, chilichonse chimagwiritsa ntchito mosiyanasiyana.
Kuphatikiza apo, EDTA ingagwiritsidwenso ntchito kutulutsa mwachangu zitsulo zowopsa zomwe zimawononga thupi la munthu ndikuchita nawo ntchito yochotsa poizoni m'thupi. Ndi mankhwala ochizira madzi.
EDTA ndi chizindikiro chofunikira, koma imagwiritsidwa ntchito poyesa zitsulo monga nickel ndi mkuwa. Ikagwiritsidwa 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 CuNa2, EDTA FeNa, EDTA MgNa2, EDTA MnNa2, EDTA ZnNa2, NTA, NTA-3Na, ndi zina zotero.
EDTA 2Na: Dzina lonse ndi disodium ethylenediaminetetraacetate, yokhala ndi formula ya mankhwala C10H14N2O8Na2• 2H2O. Amagwiritsidwa ntchito ngati sopo, chothandizira kupenta utoto, chothandizira kuchiza ulusi, chowonjezera kukongola, chowonjezera chakudya, feteleza waulimi, ndi ulimi wa m'madzi.
EDTA 4Na: Dzina lonse la ethylenediaminetetraacetic acid tetrasodium, mankhwala a formula C10H12N2O8Na4.4H2O, imagwiritsidwa ntchito ngati chofewetsa madzi, chothandizira kupanga mphira, chothandizira kuthetsa polymerization ya acrylic, chothandizira kusindikiza ndi kupaka utoto, chothandizira sopo, ndi zina zotero.
EDTA CaNa2: Dzina lonse calcium sodium ethylenediaminetetraacetate, mankhwala a C10H12N2O8CaNa2• xH2O, yomwe imagwiritsidwa ntchito ngati cholekanitsa, ndi choyeretsera madzi chomwe chimasungunuka chomwe chimatha kusungunula ma ayoni achitsulo ambiri. Kusinthanitsa kwa calcium ndi chitsulo kuti apange ma chelate okhazikika.
EDTA CuNa2: Dzina lonse la mkuwa sodium ethylenediaminetetraacetate, mankhwala a C10H12N2O8CuNa2• 2H2O, copper sodium ethylenediaminetetraacetate ndi mankhwala osungunuka m'madzi otchedwa chelating agent, ndipo copper ndi mankhwala osungunuka m'madzi.
EDTA FeNa: Dzina lonse la mkuwa sodium ethylenediaminetetraacetate, mankhwala a C10H12N2O8CuNa2• 2H2O, imagwiritsidwa ntchito ngati chothandizira kuchotsa utoto mu kujambula zithunzi. Imagwiritsidwa ntchito ngati chowonjezera mumakampani azakudya, ngati chinthu chocheperako muulimi, komanso ngati chothandizira mumakampani.
EDTA MgNa2Dzina lonse ndi magnesium sodium ethylenediaminetetraacetate, yokhala ndi formula ya mankhwala C10H12N2O8MgNa2 • 2H2O. Magnesium sodium ethylenediaminetetraacetate ndi mankhwala osungunuka m'madzi otchedwa chelating agent.
EDTA MnNa2, yomwe imadziwikanso kuti ethylenediaminetetraacetic acid manganese sodium, ili ndi formula ya mankhwala C10H12MnN2Na2O8Amagwiritsidwa ntchito ngati chinthu chopangira feteleza paulimi ndi ulimi wa maluwa, komanso ngati chinthu chochepetsera ku hydroponics.
EDTA ZnNa2Dzina lonse: Zinc sodium ethylenediaminetetraacetate, njira ya mankhwala: C10H12N2O8ZnNa2• 2H2O, zinc sodium ethylenediaminetetraacetate ndi mankhwala osungunuka m'madzi, ndipo zinc ndi mankhwala osungunuka m'madzi.
NTA: Dzina lonse ndi triacetic acid, ndipo formula ya mankhwala ndi C6H9NO6, yomwe ndi chinthu chabwino kwambiri chokonzera utoto, imagwira ntchito yokhazikika popanga styrene, ndipo imagwira ntchito ngati chothandizira komanso chophatikiza popanga thovu la polyurethane.
NTA-3Na: Dzina lonse la trisodiumaminotriacetate, fomula ya mankhwala C6H9NNa3O6, imagwiritsidwa ntchito ngati chothandizira kuyeretsa.
Ndife ogulitsa akuluakulu ku China, ngati mukufuna mtengo kapena zambiri, tikukulandirani kuti mulankhule nafe pa:
