EDTA 2NA ni iki?

Disodium edetate dihydrate (CAS 6381-92-6), izwi cyane nka EDTA-2NA, ni umunyu wa sodium divalent wa aside ethylenediaminetetraacetic (EDTA) kandi ni na wo ukoreshwa cyane mu bucuruzi bwa EDTA. Edta disodium salt dihydrate ni ikintu gisanzwe gikoreshwa mu gusya. Ikiranga cyayo cy'ingenzi ni uko ishobora gukora complexes zihamye zishobora gushonga mu mazi hamwe na iyoni zitandukanye z'icyuma. Kubwibyo, edta 2na ikoreshwa cyane mu nganda nko mu nganda, mu buvuzi, no mu binyabutabire bya buri munsi.

Ifu y'umweru ya Edta-2na irashonga mu mazi, hafi ya yose idashobora gushonga muri ethanol na ether, pH y'umuti wayo w'amazi ni hafi 5.3.

Ishyirwa mu bikorwa rya EDTA 2NA

1. Urwego rw'inganda (rufite umubare munini)

Uburyo bwo gutunganya amazi: Edta disodium salt dihydrate ni imwe mu mikoreshereze y'ingenzi. EDTA-2na ikoreshwa mu mazi atembera mu nganda, mu mazi ashyushye, mu mazi yo koga, n'ibindi. Mu gushyira Ca²⁺ na Mg²⁺ (iyoni z'amazi zikomeye) mu mazi, irinda ikorwa ry'ubugari. Muri icyo gihe, igabanya iyoni z'ibyuma nka Fe³⁺ na Cu²⁺, ikarinda ko zitera ogisijeni no kwangirika kw'ibintu bikomoka ku bimera mu mazi no kugabanya ingese mu miyoboro.

Gutunganya ibyuma: Edta-2na ikora nk'ikintu gikomeza imikorere y'amashanyarazi (iyoni z'icyuma zihanagura kugira ngo zigire irangi rimwe), isukura ibyuma (ikuramo okiside n'ibinini ku buso bw'ibyuma kugira ngo hirindwe ko iyoni z'icyuma zabangamira ibikorwa byo gusukura), n'imfasha gucapa no gusiga irangi imyenda (iyoni z'icyuma zihanagura mu mazi kugira ngo hirindwe ko imyenda yangirika nabi no kugabanuka kw'ibara ryihuse).

Isabune/Isuku: edta disodium salt dihydrate yongerwa mu ifu yo kumesa imyenda, mu mazi yoza amasahani, no mu bikoresho byo gusukura mu nganda nk' "inyunganiramirire" - igabanya imyuka y'amazi akomeye mu mazi kugira ngo yongere ubushobozi bwo gukuraho umwanda mu isabune no gukumira "isabune y'isabune" (nk'isabune idashonga ya kalisiyumu ikorwa n'isabune na Ca²⁺).

2. Ibiribwa (Inyongera zijyanye n'ibyo kurya)

Edta disodium salt dihydrate, nk'inyongeramusaruro ku biryo (yemerewe gukoreshwa muri Chinese GB 2760), ikora nk'"umusemburo uhoraho, antioxidant, icyuma gikingira":

Ku binyobwa (nk'ibinyobwa birimo karubone n'imitobe y'imbuto): Iyoni z'icyuma nka Fe³⁺ na Cu²⁺ kugira ngo zibuze ko vitamine C ishobora kwangirika no kwangirika, bityo bikamara igihe kirekire.

Ku biryo n'isosi byo mu macupa: edta-2na ibuza imisemburo ya Fe mu bikoresho by'icyuma (nk'ibati), ikabuza ibiryo guhindura ibara no guhindura uburyohe bwabyo.

Ku mavuta n'ibiribwa bikaranze: edta-2na igabanya ions z'icyuma kugira ngo ikumire oxidation no gushwanyagurika kw'amavuta (bigatuma habaho uburyohe bwo gushwanyagurika).

Icyitonderwa: Igipimo cy'umunyu wa disodium wa EDTA wo mu rwego rw'ibiribwa kigomba kugenzurwa neza (ubusanzwe ≤0.05-0.2g/kg, bitandukanye n'icyiciro cy'ibiribwa), kandi umutekano wayo wemejwe na Komisiyo ya Codex Alimentarius (CAC).

3. Urwego rw'ubuvuzi

Ibintu bifasha imiti: Edta-2na ikora nk'ikintu "gikomeza" iterwa mu gutera no kunywa ibinyobwa - igabanya ubunini bw'inguni z'icyuma mu muti w'amazi (nk'inguni za Fe na Cu zishyirwa mu gihe cyo gukora), ikarinda inguni z'icyuma kwangirika kw'imiti (nk'imiti irwanya udukoko n'ibizamini), kandi ikarinda ko imiti ikora neza kandi ikarinda umutekano w'imiti.

Umuti ugabanya uburozi bw'icyuma gikomeye: EDTA-2NA ikoreshwa mu kuvura uburozi bw'icyuma gikomeye (nk'uburozi bw'uburozi bw'uburozi bw'uburozi bwa mercure) - binyuze mu gutera disodium EDTA mu mitsi, iyoni z'icyuma zihumanya nka Pb²⁺ na Hg²⁺ mu miterere yayo ya chelate ishongera mu mazi kandi isohoka mu nkari.

Ubuvuzi bw'amenyo/Uburyo bwo kwisiga: Amazi yo kuhira imizi y'imiyoboro y'amazi akoreshwa mu buvuzi bw'amenyo (agabanya Ca²⁺ muri dentin, yoroshya dentin, kandi yoroshya isuku); Nk'ikintu "gikomeza ubwiza bw'imiyoboro y'amenyo" mu mavuta yo kwisiga, irinda iyoni z'ibyuma gutera ogisijeni no guhindura ibara ry'ibicuruzwa byo kwita ku ruhu.

4. Izindi nzego

Ubuhinzi: Edta disodium salt dihydrate, nk'inyongeramusaruro mu ifumbire mvaruganda - igabanya ibintu by'ingenzi nka Fe, Zn, na Mn ku bimera, yongera ubushobozi bwabyo bwo gushonga mu butaka, kandi yorohereza ibimera kwinjiza amazi (yirinda ko ubutaka bufatana).
