Kev tsim cov duab emulsions;nyob rau hauv cov tsiaj thiab nqaij qaib pub rau thaj tsam ntawm 10-30 qhov chaw ib lab;nyob rau hauv lub rooj ntsev raws li ib qhov chaw ntawm iodine thiab nyob rau hauv ib co dej haus;kuj nyob rau hauv tsiaj chemistry.Hauv kev kho mob, potassium iodide yog siv los tswj cov thyroid caj pas.
Potassium Iodide yog ib qhov chaw ntawm iodine thiab cov khoom noj khoom haus thiab kev noj haus ntxiv.Nws muaj nyob rau hauv crystals los yog hmoov thiab muaj ib tug solubility ntawm 1 g ntawm 0.7 ml ntawm dej ntawm 25 ° C.Nws yog suav nrog hauv cov ntsev ntsev rau kev tiv thaiv kab mob goiter.Potassium Iodide feem ntau yog siv los kho cov hluav taws xob lom vim yog ib puag ncig kev sib kis los ntawm iodine-131.
Potassium iodide yog siv lead ua dawb, granule lossis hmoov ua los ntawm cov tshuaj tiv thaiv ntawm iodine nrog cov tshuaj kub potassium hydroxide ua raws li crystallization.Nws yog heev soluble nyob rau hauv dej, cawv, thiab acetone.Potassium iodide yog thawj zaug siv los ua thawj halide hauv Talbot's calotype txheej txheem, tom qab ntawd hauv albumen ntawm cov txheej txheem iav ua raws li cov txheej txheem ntub dej collodion.Nws kuj tau siv los ua cov halide thib ob hauv cov nyiaj bromide gelatin emulsions.
