Kev Ua Haujlwm thiab Kev Siv Iodine (CAS: 7553-56-2)
1. Feem ntau yog siv rau hauv kev tsim cov iodine, siv nyob rau hauv kev tsim cov tshuaj tua kab, pub additives, dyes, iodine, xeem ntawv, tshuaj, thiab iodine tebchaw, thiab lwm yam. Cov ntaub ntawv siv rau hauv kev lag luam hluav taws xob, siab purity reagents.
2. Siv rau hauv kev npaj cov kuab tshuaj sib npaug, kev txiav txim siab ntawm iodine tus nqi, thiab calibration ntawm sodium thiosulfate tov concentration.Cov tshuaj tuaj yeem siv los ua cov tshuaj tua kab mob thiab cov duab kos duab
3. Siv nyob rau hauv kev npaj ntawm iodine thiab thinning kua nyob rau hauv photoengraving.
4. Siv rau kev tsom xam volumetric thiab colorimetric tsom xam
5. Feem ntau yog siv los ua tshuaj tua kab mob.Siv tshuaj tua kab mob thiab ua kom tsis muaj menyuam.
6. Kev siv yog cov khoom siv tseem ceeb rau kev tsim cov khoom siv tsis muaj iodine thiab cov organic iodine, feem ntau yog siv rau hauv cov tshuaj thiab kev tu cev, siv nyob rau hauv kev tsim khoom ntawm ntau yam iodine npaj, tshuaj tua kab mob, tshuaj tua kab mob, deodorant, analgesic thiab radioactive tshuaj antidote.Nws yog cov khoom siv raw ntawm cov tshuaj tua kab thiab pub additive.Bacteriostatic tus neeg sawv cev rau kev lag luam hluavtaws dyes, haus luam yeeb extinguishing agents, yees duab emulsion thiab txiav roj emulsion.Ib leeg siv lead ua prism rau kev tsim khoom siv hluav taws xob, polarizing lens rau kho qhov muag ntsuas thiab iav muaj peev xwm kis tau tus kab hluav taws xob infrared.
7. Kev soj ntsuam chemistry.Iodine tuaj yeem kuaj pom hauv iodimetry rau ntau yam tshuaj.Iodine tsim ib lub xiav complex nrog starch.Qhov kev ua haujlwm no tuaj yeem siv los kuaj cov hmoov txhuv nplej siab lossis iodine thiab yog REDOX qhia hauv iodometry.Iodine tuaj yeem siv los txheeb xyuas seb daim nqi puas yog ua los ntawm cov ntawv starchy.Iodine feem ntau yog siv los txiav txim qhov tsis txaus ntawm fatty acids (iodide), uas tshwm sim los ntawm ob daim ntawv cog lus uas cuam tshuam nrog iodine.
Iodine (CAS: 7553-56-2) yog tus neeg sawv cev oxidizing.Reacts vigorously nrog txo cov ntaub ntawv.Tsis sib haum nrog hmoov hlau nyob rau hauv lub xub ntiag ntawm dej (ignites), nrog gaseous los yog aqueous ammonia (cov ntaub ntawv explosives), nrog acetylene (reacts explosively), nrog acetaldehyde (hmoov tshuaj tiv thaiv), nrog hlau azides (cov ntaub ntawv daj tawg iodoazides), nrog hlau. hydrides (ignites), nrog hlau carbides (ignites yooj yim), nrog poov tshuaj thiab sodium (ua rau poob siab-rhiab heev explosive compounds) thiab nrog alkali-lub ntiaj teb hlau (ignites).Tsis sib haum nrog ethanol, formamide, chlorine, bromine, bromine trifluoride, chlorine trifluoride.
Iodine vapors yog ua rau khaus rau qhov muag, qhov ntswg thiab cov mucous daim nyias nyias.Inhalation yuav ua rau mob taub hau, khaus, thiab congestion ntawm lub ntsws.Oralintake tuaj yeem ua rau kub hnyiab ntawm qhov ncauj, ntuav, raws plab, thiab mob plab.Kev sib cuag ntawm daim tawv nqaij tuaj yeem ua rau pob khaus.
Iodine yog noncombustible thiab nyob rau hauv nws tus kheej sawv cev rau ib tug negligible hluav taws txaus ntshai thaum raug tshav kub los yog nplaim taws.Txawm li cas los xij, thaum rhuab, nws yuav nce qhov kub ntawm cov khoom siv hluav taws xob.
looj tsom iav dub thiab hnab looj tes roj hmab yuav tsum hnav thaum tuav iodine, thiab kev ua haujlwm uas muaj ntau yuav tsum tau ua nyob rau hauv lub fume hood kom tsis txhob raug iodine vapor los yog plua plav los ntawm kev nqus pa.
Iodine ruaj khov nyob rau hauv qhov kub thiab txias.Iodine tuaj yeem cuam tshuam nrog acetylene, ammonia, acetaldehyde, formaldehyde, acrylonitrile, hmoov antimony, tetraamine tooj liab (II) sulfate, thiab kua chlorine.Iodine tuaj yeem tsim rhiab heev, tawg sib xyaw nrog potassium, sodium, thiab oxygen difluoride;ammonium hydroxide reacts nrog iodine los tsim nitrogen triiodide, uas detonates ntawm ziab.
