Ethylenediaminetetraacetic acid (EDTA)
Ethylenediaminetetraacetic acid (EDTA) inhengo yeorganic ine kemikari formula C10H16N2O8. Ihupfu chena pane tembiricha yekamuri uye kumanikidza. Icho chinhu chinogona kuita neMg2+Chelating agent inosanganisa divalent simbi ions yakadai seCa2+, Mn2+uye, Fe2+.
EDTA chinhu chakakosha chelating agent. EDTA ine huwandu hwakawanda hwemashandisirwo uye inogona kushandiswa seyakajeka uye kugadzirisa mhinduro yekugadziriswa kwemavara anonzwa zvinhu, dyeing aids, cosmetic additives, stabilizers, uye synthetic rubber polymerization initiators, EDTA chinhu chinomiririra chelating agents. Inogona kuumba yakagadzikana-inonyungudika mvura yakaoma ine alkali simbi, isingawanzo pasi zvinhu, uye shanduko simbi. Kuwedzera kune sodium munyu, kunewo ammonium munyu uye akasiyana munyu akadai iron, magnesium, calcium, mhangura, manganese, zingi, cobalt, aruminiyamu, etc., mumwe nomumwe ane kushandiswa kwakasiyana.
Pamusoro pezvo, EDTA inogona zvakare kushandiswa kukurumidza kuburitsa simbi dzinokuvadza kubva mumuviri wemunhu uye kuita basa rekubvisa. Iyo zvakare mushonga wekuchenesa mvura.
EDTA zvakare chiratidzo chakakosha, asi inoshandiswa kutsika simbi senge nickel nemhangura. Kana yashandiswa, inofanirwa kushandiswa pamwe chete neammonia kuita sechiratidzo.
Kune akawanda marudzi eEDTA, uye kambani yedu inogadzira EDTA 2Na EDTA 4Na, EDTA CaNa.2, EDTA CuNa2, EDTA FeNa, EDTA MgNa2, EDTA MnNa2, EDTA ZnNa2, NTA, NTA-3Na, nezvimwewo.
EDTA 2Na: Zita rakazara rinonzi disodium ethylenediaminetetraacetate, ine kemikari formula C.10H14N2O8Na2• 2H2O. Inoshandiswa se detergent, dyeing aid, fiber treatment agent, cosmetic additive, food additive, agriculture micro fertilizer, uye marine aquaculture.
EDTA 4Na: Zita rakazara ethylenediaminetetraacetic acid tetrasodium, kemikari formula C10H12N2O8Na4.4H2O, inoshandiswa sechinhu chinopfavisa mvura, synthetic rubber catalyst, acrylic polymerization termination agent, kudhinda uye dhayi mubatsiri, detergent mubatsiri, nezvimwe.
EDTA CaNa2: Zita rakazara calcium sodium ethylenediaminetetraacetate, kemikari formula C10H12N2O8CaNa2• xH2O, inoshandiswa semugadziri wekuparadzanisa, imvura inonyunguduka chelating agent inogona chelate multivalent iron ions. Calcium nesimbi kuchinjana kuumba mamwe akagadzikana chelates.
EDTA CuNa2: Zita rakazara mhangura sodium ethylenediaminetetraacetate, kemikari formula C10H12N2O8CuNa2• 2H2O, copper sodium ethylenediaminetetraacetate inonyungudika mumvura chelating agent, uye mhangura ichelating agent.
EDTA FeNa: Zita rakazara mhangura sodium ethylenediaminetetraacetate, kemikari formula C10H12N2O8CuNa2• 2H2O, rinoshandiswa se decolorizing agent mukutora mifananidzo. Inoshandiswa sechinhu chinowedzera muindasitiri yechikafu, sechinhu chinoteedzera mukurima, uye sechinhu chinokonzeresa muindasitiri.
EDTA MgNa2: Zita rakazara magnesium sodium ethylenediaminetetraacetate, ine kemikari formula C10H12N2O8MgNa2 • 2H2O. Magnesium sodium ethylenediaminetetraacetate is a water-soluble chelating agent.
EDTA MnNa2, inozivikanwawo se ethylenediaminetetraacetic acid manganese sodium, ine kemikari formula C10H12MnN2Na2O8. Inoshandiswa sechinhu chefoliar fertilization mukurima uye horticulture, pamwe chete nechinhu chinoteedzera che hydroponics.
EDTA ZnNa2: Zita rakazara: Zinc sodium ethylenediaminetetraacetate, kemikari formula: C10H12N2O8ZnNa2• 2H2O, zinc sodium ethylenediaminetetraacetate inonyungudika nemvura inochetura, uye zingi inochetura.
NTA: Zita rakazara rinonzi triacetic acid, kemikari formula iC6H9NO6, inova yakanaka kugadzirisa mugadziri muindasitiri yedhayi, inoita basa rekudzikamisa mukugadzirwa kwestyrene, uye inoshanda sechinhu chinokonzeresa uye chakaomarara mukugadzira polyurethane furo.
NTA-3Na: Zita rakazara trisodiumaminotriacetate, kemikari formula C6H9NNa3O6, inoshandiswa sechelating agent.
