I-Sodium Metabisulphite: Inhlanganisela Yamakhemikhali Ehlukahlukene

I-sodium metabisulphite (i-Na₂S₂O₅), eyaziwa nangokuthi i-sodium pyrosulfite, iyimpushana emhlophe ecwebezelayo esetshenziswa kabanzi ezimbonini zonkana ngenxa yezakhiwo zayo zokulondoloza kanye ne-antioxidant. Njengoba yaziwa njenge-E223 e-European Union, le nhlanganisela idlala indima ebalulekile ekongiweni kokudla, ekuhlanzeni amanzi, nokunye okwengeziwe, naphezu kokudinga ukuphathwa ngokucophelela ngenxa yesimo sayo sokusebenza.

I-sodium metabisulphite iqukethe ama-ion amabili e-sodium kanye ne-disulfite anion (S₂O₅²⁻). Kubonakala njengempushana emhlophe, egeleza mahhala enephunga elimnandi le-sulphur dioxide (SO₂). Incibilika kakhulu emanzini, yakha i-sodium bisulfite (NaHSO₃), futhi ibola ku-150 ° C, ikhiphe i-SO₂ gas. Isixazululo sayo esine-asidi sisebenza njenge-ejenti yokunciphisa eqinile.

Izicelo:
1.Imboni Yokudla:
●Ilondoloza izithelo ezomisiwe, amawayini, kanye nokudla okugayiwe ukuze kuvinjwe ukukhula kwamagciwane kanye ne-oxidation.
●Ivimbela ukunsundu kwemifino nezithelo.
2. Ukwenza iwayini:
● Hlanza izinto zokusebenza futhi uzinzise kufanele ngokuqeda amagciwane angafunwa kanye nemvubelo.
3.Ukwelashwa kwamanzi:
●Yenza i-chlorine ibe maphakathi futhi isebenze njengesibulala-magciwane ezinhlelweni zamanzi angcolile.
I-4.Isithombe: Ingxenye yokuthuthukisa izixazululo zokulungisa izithombe ngokususa isiliva eleqile.
5.Izimonyo:Isigcinakaliso kumakhilimu nemikhiqizo yezinwele ukwelula impilo yeshalofu.

Ukuphepha Nokuphatha:
● Izingozi Zezempilo: Ikhulula i-SO₂ lapho ithintana nama-acids noma umswakama, ibeka izingozi zokuphefumula. Abantu abangezwani ne-sulfite bangase babe nokungezwani komzimba.
● Izinyathelo Zokuzivikela: Sebenzisa amagilavu, izibuko, namamaski; qinisekisa ukungena komoya. Gcina kude nama-acids nama-oxidizers.
● Usizo Lokuqala: Hlanza izindawo ezivulekile ngamanzi; funa usizo lwezokwelapha ukuze uhogele umoya noma ukumunce.
