Taw qhia
Iodine yog cov khoom siv tshuaj nrog cov cim tshuaj I thiab atomic tooj 53. Iodine yog cov khoom tsis yog xim hlau uas feem ntau pom muaj nyob hauv cov dej hiav txwv thiab av. Hauv qab no yog cov lus piav qhia ntawm qhov xwm txheej, kev siv, kev tsim thiab cov ntaub ntawv kev nyab xeeb ntawm iodine:
1. Xwm:
-Cov tsos mob: Iodine yog xiav-dub siv lead ua, muaj nyob rau hauv cov khoom muaj zog.
-Melting point: Iodine tuaj yeem hloov ncaj qha los ntawm cov khoom mus rau lub xeev gaseous nyob rau hauv huab cua kub, uas yog hu ua sub-limation. Nws melting point yog hais txog 113.7 ° C.
-Boiling point: Lub boiling point ntawm iodine ntawm ib txwm siab yog hais txog 184.3 ° C.
-Density: Qhov ceev ntawm iodine yog li 4.93g / cm³.
-Solubility: Iodine yog insoluble nyob rau hauv dej, tab sis soluble nyob rau hauv ib co organic solvents xws li cawv, cyclohexane, thiab lwm yam.
2. Siv:
- Pharmaceutical field: Iodine yog dav siv rau kev tua kab mob thiab ua kom tsis muaj menyuam, thiab feem ntau pom muaj nyob rau hauv cov tshuaj tua kab mob thiab cov khoom tu qhov ncauj.
-Kev lag luam khoom noj khoom haus: iodine ntxiv raws li Iodine hauv cov lus ntsev los tiv thaiv kab mob iodine deficiency, xws li goiter.
- Kev sim tshuaj: iodine tuaj yeem siv los kuaj pom muaj cov hmoov txhuv nplej siab.
3. Txoj kev npaj:
- Iodine tuaj yeem muab rho tawm los ntawm kev hlawv seaweed, lossis los ntawm kev rho tawm ore uas muaj iodine los ntawm cov tshuaj tiv thaiv.
-Ib qho tshuaj tiv thaiv rau kev npaj iodine yog ua rau Iodine nrog oxidizing tus neeg sawv cev (xws li hydrogen peroxide, sodium peroxide, thiab lwm yam) los tsim iodine.
4. Cov ntaub ntawv kev nyab xeeb:
- Iodine tej zaum yuav ua rau khaus tawv nqaij thiab qhov muag ntawm qhov siab, yog li koj yuav tsum tau xyuam xim rau kev siv cov cuab yeej tiv thaiv tus kheej, xws li hnab looj tes thiab tsom iav, thaum tuav Iodine.
- Iodine muaj toxicity tsawg, tab sis yuav tsum tsis txhob noj iodine ntau dhau kom tsis txhob muaj iodine lom.
- Iodine tuaj yeem tsim cov tshuaj lom Iodine hydrogen gas thaum kub kub lossis qhib nplaim taws, yog li tsis txhob sib cuag nrog cov khoom siv hluav taws xob lossis oxidants.
