Intshayelelo
Iodine sisiqalelo sekhemikhali esinophawu lwekhemikhali I kunye nenombolo yeathomu engu-53. Iodine sisiqalelo esingeyontsimbi esixhaphake kwindalo elwandle nasemhlabeni. Oku kulandelayo yinkcazo yendalo, ukusetyenziswa, ukuqulunqwa kunye nolwazi lokhuseleko lwe-Iodine:
1. Indalo:
-Ukubonakala: Iodine yikristale eluhlaza okwesibhakabhaka, eqhelekileyo kwisimo esiqinileyo.
-Indawo yokunyibilika: I-iodine inokutshintsha ngokuthe ngqo ukusuka kwisigxina ukuya kwimeko yegesi phantsi kobushushu bomoya, obubizwa ngokuba yi-sub-limation. Indawo yayo yokunyibilika imalunga ne-113.7 ° C.
-Indawo yokubilisa: Indawo yokubila ye-Iodine kuxinzelelo oluqhelekileyo malunga ne-184.3 ° C.
-Ubuninzi: Ubuninzi be-Iodine bumalunga ne-4.93g/cm³.
-I-Solubility: Iodine ayinyibiliki emanzini, kodwa i-soluble kwezinye izinyibilikisi eziphilayo ezifana notywala, i-cyclohexane, njl.
2. Sebenzisa:
-Intsimi ye-Pharmaceutical: Iodine isetyenziswa ngokubanzi kwi-disinfection kunye ne-sterilization, kwaye ifumaneka ngokuqhelekileyo kwi-disinfection yesilonda kunye neemveliso zokunakekelwa ngomlomo.
-Ishishini lokutya: Iodine yongezwa njenge-Iodine kwityuwa yetafile ukukhusela izifo zokunqongophala kwe-Iodine, njenge-goiter.
-Uvavanyo lwemichiza: Iodine ingasetyenziselwa ukubona ubukho bestatshi.
3. Indlela yokulungiselela:
- Iodine inokukhutshwa ngokutshisa i-seaweed, okanye ngokukhupha i-ore ene-iodine ngokusabela kweekhemikhali.
-Impendulo eqhelekileyo yokulungisa i-Iodine kukusabela i-Iodine kunye ne-oxidizing agent (efana ne-hydrogen peroxide, i-sodium peroxide, njl.) ukuvelisa i-Iodine.
4. Ulwazi ngoKhuseleko:
- Iodine inokucaphukisa ulusu kunye namehlo kwiindawo eziphezulu, ngoko kufuneka ubeke ingqalelo ekusebenziseni izixhobo zokukhusela zomntu, njengeiglavu kunye nezibuko, xa ubamba i-Iodine.
- Iodine inetyhefu ephantsi, kodwa kufuneka ikuphephe ukuthatha kakhulu i-iodine ukunqanda ityhefu ye-iodine.
- Iodine inokuvelisa igesi eyityhefu ye-Iodine hydrogen kubushushu obuphezulu okanye idangatye elivulekileyo, ngoko kunqande ukudibana nezinto ezinokutsha okanye ii-oxidants.
