Sodium Metabisulphite: Ngwakọta kemịkalụ dị iche iche

Sodium metabisulphite (Na₂S₂O₅), makwaara dị ka sodium pyrosulfite, bụ ọcha crystalline ntụ ntụ nke a na-ejikarị n'ofe ụlọ ọrụ maka ihe nchekwa ya na antioxidant. N'ịghọta dị ka E223 na European Union, ogige a na-arụ ọrụ dị mkpa na nchekwa nri, ọgwụgwọ mmiri na ihe ndị ọzọ, n'agbanyeghị na ọ chọrọ iji nlezianya mee ihe n'ihi ọdịdị mmeghachi omume ya.

Sodium metabisulphite nwere ion sodium abụọ na anion disulfite (S₂O₅²⁻). Ọ na-apụta dị ka ntụ ntụ na-acha ọcha, nke na-enwere onwe ya nke nwere ísì sọlfọ dioxide (SO₂) na-esi ísì. Ọ na-agbaze nke ukwuu n'ime mmiri, na-akpụ sodium bisulfite (NaHSO₃), na ire ere na 150 Celsius, na-ahapụ SO₂ gas. Ihe ngwọta acid ya na-arụ ọrụ dị ka onye na-ebelata ike.

Ngwa:
1. Ụlọ ọrụ nri:
● Ihe nchekwa n'ime mkpụrụ osisi a mịrị amị, mmanya, na ihe oriri a na-edozi iji gbochie uto microbial na oxidation.
●Na-egbochi browning enzymatic na akwụkwọ nri na mkpụrụ osisi.
2. Ime mmanya:
● Na-asachapụ akụrụngwa ma kwụsie ike ga-enwerịrị site na iwepu nje bacteria na yist na-achọghị.
3. Ọgwụgwọ mmiri:
● Na-ewepụ chlorine ma na-arụ ọrụ dị ka ihe na-egbu egbu n'ime usoro mmiri mkpofu.
4.Photography: Akụkụ nke na-emepụta ihe ngwọta iji dozie ihe oyiyi site n'iwepụ ọlaọcha na-abaghị uru.
5.Cosmetics: Preservative na creams na ntutu na-agbatị ndụ ndụ.

Nchekwa na njikwa:
●Ihe ize ndụ ahụike: Na-ewepụta SO₂ mgbe ọ na-akpakọrịta na acid ma ọ bụ mmiri, na-ebute ihe egwu iku ume. Ndị nwere mmetụta sulfite nwere ike ịnweta mmeghachi ahụ nfụkasị ahụ.
● Ihe ndị e ji echebe: Jiri gloves, goggles, na masks; hụ na ventilashion. Chekwaa pụọ ​​na acids na oxidizers.
● Enyemaka Mbụ: Jiri mmiri na-asachapụ ebe ndị a kpuchiri ekpuchi; chọọ enyemaka ahụike maka ikuku ume ma ọ bụ iri nri.
