Iyini i-EDTA 2NA?

I-Disodium edetate dihydrate (CAS 6381-92-6), evame ukubizwa ngokuthi i-EDTA-2NA, iyisimo sikasawoti we-sodium esi-divalent se-ethylenediaminetetraacetic acid (EDTA) futhi iyindlela evamile futhi esetshenziswa kabanzi yezentengiselwano ye-EDTA. I-Edta disodium salt dihydrate iyi-ejenti ejwayelekile ye-chelating. Isici sayo esiyinhloko ukuthi ingakha ama-complex aqinile ancibilikayo emanzini ane-ion ehlukahlukene yensimbi. Ngakho-ke, i-edta 2na isetshenziswa kabanzi ezimbonini ezifana nezimboni, ezokwelapha, kanye namakhemikhali ansuku zonke.

Impuphu emhlophe yekristalu ye-Edta-2na, encibilikayo emanzini, cishe engancibiliki ku-ethanol kanye ne-ether, inani le-pH lesisombululo sayo samanzi licishe libe ngu-5.3.

Ukusetshenziswa kwe-EDTA 2NA

1. Umkhakha wezimboni (onesilinganiso esiphezulu)

I-ejenti yokwelapha amanzi: I-Edta disodium salt dihydrate ingenye yezindlela ezisetshenziswa kakhulu. I-EDTA-2na isetshenziswa emanzini ajikelezayo ezimbonini, emanzini abilayo, emanzini okubhukuda, njll. Ngokufaka i-Ca²⁺ kanye ne-Mg²⁺ (ama-ion amanzi aqinile) emanzini, ivimbela ukwakheka kwesikali. Ngesikhathi esifanayo, ifaka i-chelate ama-ion ensimbi njenge-Fe³⁺ kanye ne-Cu²⁺, iwavimbele ekuvuseleleni i-oxidation kanye nokuwohloka kwezinto eziphilayo emanzini kanye nokunciphisa ukugqwala kwepayipi.

Ukucubungula insimbi: I-Edta-2na isebenza njengesiqinisi sezixazululo ze-electroplating (ukufaka ama-ion ensimbi ukuze kuqinisekiswe ukumbozwa okufanayo), isihlanzi sensimbi (ukususa ama-oxide kanye nesikali ezindaweni zensimbi ukuze kuvinjelwe ama-ion ensimbi ukuthi angaphazamisi imiphumela yokuhlanza), kanye nomsizi wokunyathelisa nokudaya izindwangu (ukufaka ama-ion ensimbi emanzini ukuze kuvinjelwe ukudaya okungalingani kwezindwangu kanye nokwehla kokushesha kombala).

I-detergent/i-ejenti yokuhlanza: i-edta disodium salt dihydrate ifakwa ku-laundry powder, uketshezi lokuwasha izitsha, kanye nama-ejenti okuhlanza ezimbonini "njengento yokuthambisa amanzi" - ehlanganisa ama-ion amanzi aqinile emanzini ukuze kuthuthukiswe ikhono lokuhlanza ama-detergent futhi kuvinjelwe ukwakheka "kwe-soap scum" (njengensipho ye-calcium enganyibiliki eyenziwe ngensipho kanye ne-Ca²⁺).

2. Insimu Yokudla (Izithasiselo Ezihambisanayo)

I-Edta disodium salt dihydrate, njengesithasiselo sokudla (esivunyelwe ukusetshenziswa ku-Chinese GB 2760), isebenza njenge-"stabilizer, antioxidant, i-metal chelating agent":

Ngeziphuzo (njengeziphuzo ezine-carbonated kanye namajusi ezithelo): Faka ama-ion ensimbi anjenge-Fe³⁺ kanye ne-Cu²⁺ ukuze uwavimbele ekuvuseleleni i-oxidation kanye nokuwohloka kwe-vitamin C, ngaleyo ndlela wandise isikhathi sokuphila.

Kokudla okusemathinini kanye nama-sauce: i-edta-2na ivimbela ukuncibilika kwama-ion e-Fe ezitsheni zensimbi (njenge-tinplate), ivimbela ukudla ukuthi kungashintshi umbala futhi kushintshe ukunambitheka kwako.

Kumafutha nokudla okuthosiwe: i-edta-2na i-chelates i-metal ion ukuvimbela ukubola kanye nokubola kwamafutha (okuholela ekunambithekeni okubolayo).

Qaphela: Umthamo wosawoti we-disodium we-EDTA wezinga lokudla kumele ulawulwe ngokuqinile (ngokuvamile ≤0.05-0.2g/kg, kuyahlukahluka ngesigaba sokudla), futhi ukuphepha kwawo kuqinisekiswe yi-Codex Alimentarius Commission (CAC).

3. Insimu yezokwelapha

Izinto ezisizayo ezidakamizwa: I-Edta-2na isebenza "njengesiqinisi" sokujova kanye noketshezi oluphuzwayo - inciphisa inani lama-ion ensimbi emuthini owuketshezi (njengama-ion e-Fe kanye ne-Cu angeniswe ngesikhathi senqubo yokukhiqiza), ivimbela ama-ion ensimbi ekubangeni ukuwohloka kwemithi (njengama-antibiotic kanye nemithi yamavithamini), kanye nokuqinisekisa ukusebenza kahle nokuphepha kwemithi.

Isihlanzisi sensimbi esindayo: I-EDTA-2NA isetshenziselwa ukwelapha ubuthi bensimbi esindayo (njengobuthi be-lead kanye nobuthi be-mercury) - ngokujova nge-disodium EDTA ngemithambo yegazi, ama-ion ensimbi anobuthi njenge-Pb²⁺ kanye ne-Hg²⁺ ngaphakathi kwe-chelate form yayo encibilikayo emanzini futhi ikhishwa ngomchamo.

Ukwelapha Amazinyo/Izimonyo: Uketshezi lokunisela imisele yezimpande olusetshenziswa ekwelapheni amazinyo (ukuhlanza i-Ca²⁺ ku-dentin, ukuthambisa i-dentin, kanye nokwenza kube lula ukuhlanza); Njenge-"metal ion stabilizer" ezimonyweni, luvimbela ama-metal ion ukuthi angabangeli ukubola kanye nokushintsha kombala wemikhiqizo yokunakekelwa kwesikhumba.

4. Ezinye izinkambu

Ezolimo: I-Edta disodium salt dihydrate, njengesithako somanyolo wezinto ezincane - ihlanganisa izinto ezincane ezibalulekile njenge-Fe, Zn, kanye ne-Mn zezitshalo, ikhulisa ukuncibilika kwazo enhlabathini, futhi yenza kube lula ukumuncwa kwezitshalo (ukugwema ukunamathela yinhlabathi).
