I-MF:KI
Inombolo ye-EINECS: 231-442-4
Izinga Elijwayelekile: Izinga Lokuphakelayo, Izinga Lokudla, Izinga Lemithi, Izinga Lobuchwepheshe, Izinga Lezimboni, Izinga Lemithi
Ukubukeka: i-powder emhlophe noma ecishe ibe mhlophe noma i-crystal engenambala
I-potassium iodide iyikristalu elimhlophe noma impuphu. I-hygroscopic kancane emoyeni omanzi, ikhipha i-iodine yamahhala isikhathi eside futhi iphenduke iphuzi, futhi ingakha inani elincane le-iodide. Ukukhanya nomswakama kungasheshisa ukubola. I-1 g yancibilikiswa ku-0.7 ml wamanzi, u-0.5 ml wamanzi abilayo, u-22 ml we-ethanol, u-8 ml we-ethanol ebilayo, u-51 ml we-ethanol ephelele, u-8 ml we-methanol, u-7.5 ml we-acetone, u-2 ml we-glycerol, kanye no-2.5 ml we-ethylene glycol. Isixazululo sayo samanzi asithathi hlangothi noma sine-alkaline kancane futhi singancibilikisa i-iodine. Isixazululo samanzi sizophinde sincibilike futhi sishintshe sibe nombala ophuzi, okungavinjelwa ngokungeza inani elincane le-alkali. Ubuningi obuhlobene bungu-3.12. Izinga lokushisa lingu-680 ° C. Iphuzu lokubila lingu-1330 ° C. Umthamo obulalayo olinganiselwayo (igundane, umthambo) wawungu-285 mg/kg. Isetshenziswa kabanzi ekuhlaziyweni kwevolumu yezindlela ze-iodometric ukulungiselela izixazululo ze-titration. Izindlela ezifana ne-Beredes, i-Modified White, i-MS, kanye ne-RM zilungiswa ngama-haplotypes. Ukuhlolwa kwendle, njll. Isithombe. Imithi.

I-Potassium Iodideiwumthombo we-iodine kanye nesengezo sokudla. Ikhona njengamakristalu noma impuphu futhi inokuncibilika okungu-1 g ku-0.7 ml wamanzi ku-25°c. Ifakiwe kusawoti wetafula ukuvimbela i-goiter. I-Potassium Iodide isetshenziswa kakhulu ekwelapheni ubuthi bemisebe ngenxa yokungcoliswa kwemvelo yi-iodine-131. Iphinde ikhiqizwe ngezithombe; ekudleni kwezilwane nezinkukhu kuze kufike ezingxenyeni eziyi-10-30 ngesigidi; kusawoti wetafula njengomthombo we-iodine nakwamanye amanzi okuphuza; kanye nakumakhemikhali ezilwane. Kwezokwelapha, i-potassium iodide isetshenziselwa ukulawula indlala yegilo.
I-potassium iodide yaqala ukusetshenziswa njenge-halide eyinhloko enqubweni ye-calotype kaTalbot, yabe isisetshenziswa enqubweni ye-albumen engilazini elandelwa inqubo ye-collodion emanzi. Yasetshenziswa futhi njenge-halide yesibili kuma-emulsion e-gelatin esiliva e-bromide, ukudla kwezilwane, ama-catalyst, amakhemikhali ezithombe, kanye nokuhlanzeka. I-potassium iodide ikhiqizwa ngokuphendula kwe-potassium hydroxide ne-iodine. Umkhiqizo uhlanzwa ngokukristala emanzini. I-potassium iodide iyinhlanganisela ye-ionic lapho ama-ion e-iodine nama-ion esiliva angakha khona i-iodide yesiliva ephuzi (uma ivezwa ekukhanyeni, ingabola, ingasetshenziswa ukwenza ifilimu yezithombe esheshayo), i-silver nitrate ingasetshenziswa ukuqinisekisa ukuba khona kwama-ion e-iodine.
