Yintoni i-EDTA 2NA?

I-Disodium edetate dihydrate (CAS 6381-92-6), edla ngokubizwa ngokuba yi-EDTA-2NA, luhlobo lwetyuwa yesodium edivalent ye-ethylenediaminetetraacetic acid (EDTA) kwaye ikwaluhlobo oluqhelekileyo nolusetyenziswa kakhulu kwezorhwebo lwe-EDTA. I-Edta disodium salt dihydrate yiarhente eqhelekileyo ye-chelating. Uphawu lwayo oluphambili kukuba inokwenza ii-complexes ezizinzileyo ezinyibilikayo emanzini ezinee-ion ezahlukeneyo zesinyithi. Ke ngoko, i-edta 2na isetyenziswa kakhulu kumashishini afana nemizi-mveliso, amayeza, kunye neekhemikhali zemihla ngemihla.

Umgubo omhlophe wekristale we-Edta-2na, onyibilikayo emanzini, onganyibilikiyo kwi-ethanol nakwi-ether, ixabiso le-pH yesisombululo sayo samanzi limalunga ne-5.3.

Ukusetyenziswa kwe-EDTA 2NA

1. Icandelo lemizi-mveliso (elinomlinganiselo ophezulu)

Isixhobo sonyango lwamanzi: I-Edta disodium salt dihydrate yenye yezona zinto zisetyenziswa kakhulu. I-EDTA-2na isetyenziswa kumanzi ajikelezayo emizi-mveliso, amanzi ebhoyila, amanzi edamini lokudada, njl. Ngokusebenzisa i-Ca²⁺ kunye ne-Mg²⁺ (ii-ion zamanzi aqinileyo) emanzini, ithintela ukwakheka kwesikali. Kwangaxeshanye, inciphisa ii-ion zesinyithi ezifana ne-Fe³⁺ kunye ne-Cu²⁺, ithintela ukuba zingasebenzisi i-oxidation kunye nokuwohloka kwezinto eziphilayo emanzini kwaye inciphise ukubola kwepayipi.

Ukulungiswa kwesinyithi: I-Edta-2na isebenza njengesiqinisi sezisombululo ze-electroplating (ii-ion zesinyithi ezichebayo ukuqinisekisa ukugquma okufanayo), isicoci sesinyithi (esusa ii-oxides kunye ne-scale kwiindawo zesinyithi ukuthintela ii-ion zesinyithi ukuba zingaphazamisi imiphumo yokucoca), kunye nomncedisi wokuprinta kunye nokudaya amalaphu (ii-ion zesinyithi ezichebayo emanzini ukuthintela ukudaywa okungalinganiyo kwamalaphu kunye nokuncipha kokukhawuleza kombala).

Isixhobo sokucoca/sokucoca: i-edta disodium salt dihydrate yongezwa kwi-laundry powder, kwi-dish washwashing liquid, nakwii-industrial cleaners njenge-"water softener" - i-chelating hard water ion emanzini ukuphucula amandla okucoca iisepha nokuthintela ukwakheka kwe-"soap scum" (njengesepha ye-calcium enganyibilikiyo eyenziwe yisepha kunye ne-Ca²⁺).

2. Intsimi yokutya (Izongezo ezihambelanayo)

I-Edta disodium salt dihydrate, njengesongezelelo sokutya (esivumelekileyo ukusetyenziswa kwi-Chinese GB 2760), isebenza njenge-"stabilizer, antioxidant, i-metal chelating agent":

Kwiziselo (ezifana neziselo ezine-carbonated kunye neejusi zeziqhamo): Ii-ion zesinyithi ze-Chelate ezifana ne-Fe³⁺ kunye ne-Cu²⁺ ukuthintela ukuba zingashukumisi i-oxidation kunye nokuwohloka kwe-vitamin C, ngaloo ndlela zandise ubomi beshelufu.

Kwizinto ezisemathinini kunye neesosi: i-edta-2na ithintela ukunyibilika kwee-ion ze-Fe kwizikhongozeli zesinyithi (ezifana ne-tinplate), ithintela ukutya ekutshintsheni umbala nokutshintsha incasa yako.

Kwioyile nokutya okuqhotsiweyo: i-edta-2na i-chelates i-ions zesinyithi ukuthintela i-oxidation kunye nokurhawuzelela kweeoyile (okubangela incasa erhawuzekileyo).

Qaphela: Umlinganiselo wetyuwa ye-disodium ye-EDTA ekumgangatho wokutya kufuneka ulawulwe ngokungqongqo (ngesiqhelo i-≤0.05-0.2g/kg, yahluka ngokweentlobo zokutya), kwaye ukhuseleko lwayo luqinisekiswe yiCodex Alimentarius Commission (CAC).

3. Icandelo lezonyango

Izinto ezincedisayo kwiyeza: I-Edta-2na isebenza "njenge-stabilizer" yeenaliti kunye nolwelo oluselwayo - i-chelating trace rates of metal ions kwiyeza elilulwelo (ezifana nee-Fe kunye nee-Cu ions ezifakwe ngexesha lenkqubo yemveliso), ithintela ii-metal ions ekubeni zibangele ukubola kwamayeza (ezifana nee-antibiotics kunye namayeza eevithamini), kwaye iqinisekisa ukusebenza kakuhle kunye nokhuseleko lwamayeza.

Isicoci sesinyithi esinzima: I-EDTA-2NA isetyenziselwa ukunyanga ubuthi besinyithi esinzima (njengobuthi belothe kunye nobuthi be-mercury) - ngokufaka i-disodium EDTA ngemithambo yegazi, ii-ion zesinyithi ezinobuthi ezifana ne-Pb²⁺ kunye ne-Hg²⁺ ngaphakathi kwee-complexes zayo ezinyibilikayo emanzini ze-chelate kwaye zikhutshwa ngomchamo.

Unyango lwamazinyo/Izinto zokuthambisa: Ulwelo lokunkcenkceshela umjelo weengcambu olusetyenziswa kunyango lwamazinyo (ukucoca i-Ca²⁺ kwi-dentin, ukuthambisa i-dentin, kunye nokwenza kube lula ukucoca); Njenge-"metal ion stabilizer" kwizithambiso, ithintela i-metal ion ukuba ingabangela i-oxidation kunye nokutshintsha kombala weemveliso zokhathalelo lolusu.

4. Amanye amasimi

Ezolimo: Ityuwa ye-Edta disodium dihydrate, njengesongezelelo kwizichumisi ze-trace element - inciphisa ii-trace elements ezibalulekileyo ezifana ne-Fe, i-Zn, kunye ne-Mn kwizityalo, yonyusa ukunyibilika kwazo emhlabeni, kwaye iququzelela ukufunxwa kwezityalo (ukuphepha ukunamathela ngumhlaba).
