Iodine yog ib qho tshuaj lom neeg nrog lub cim I thiab atomic tooj 53. Nws yog ib qho tsis yog xim hlau halogen uas muaj nyob hauv dej hiav txwv thiab pob zeb. Nws yog ib qho tseem ceeb uas yuav tsum tau los ntawm cov thyroid caj pas los tsim cov tshuaj hormones uas tswj cov metabolism. Iodine kuj tseem siv rau hauv ntau yam kev lag luam thiab kev siv tshuaj. Hauv kab lus no, peb yuav tham txog peb txoj hauv kev ntawm kev npaj iodine.
1. Los ntawm Seaweed
Keeb kwm, thawj qhov chaw ntawm iodine yog seaweed. Seaweed muaj ntau ntau iodine, uas nws absorbs los ntawm seawater. Cov txheej txheem ntawm kev rho tawm iodine los ntawm seaweed yuav hlawv cov seaweed thiab sau cov tshauv. Tom qab ntawd cov tshauv yog leached nrog dej kom yaj cov iodine. Cov tshuaj yog tom qab ntawd evaporated kom tau cov khoom siv iodine.
2. Los ntawm Iodides
Iodine kuj tseem tuaj yeem npaj los ntawm iodides xws li potassium iodide, sodium iodide, lossis calcium iodide, thiab lwm yam. Cov txheej txheem cuam tshuam nrog oxidizing iodide nrog oxidizing tus neeg sawv cev xws li chlorine lossis hydrogen peroxide. Tom qab ntawd cov iodine yog sib cais los ntawm kev daws los ntawm kev pom, thiab cov khoom siv iodine tau txais los ntawm evaporation.
3. Los ntawm Brine
Lwm txoj kev ntawm kev npaj iodine yog los ntawm kev rho tawm ntawm iodine los ntawm brine. Brine yog ib qho kev daws ntawm ntsev thiab dej uas muaj nyob rau hauv ntsev mines thiab ntsev pas dej. Nws muaj me me ntawm iodine, uas tuaj yeem raug cais los ntawm ntau yam txheej txheem tshuaj. Ib qho txheej txheem zoo li no suav nrog kev kho cov brine nrog chlorine kom oxidize iodide rau iodine. Tom qab ntawd cov iodine yog cais los ntawm kev daws los ntawm kev pom thiab evaporation.
Hauv kev xaus, iodine yog ib qho tseem ceeb uas yuav tsum tau los ntawm tib neeg lub cev rau kev ua haujlwm ntawm cov thyroid caj pas. Nws kuj yog siv rau hauv ntau yam kev lag luam thiab kev siv tshuaj. Peb txoj kev npaj iodine yog los ntawm seaweed, los ntawm iodides, thiab los ntawm brine. Tag nrho peb txoj kev muaj lawv qhov zoo thiab qhov tsis zoo, tab sis lawv txhua tus ua haujlwm rau lub hom phiaj ntawm kev tsim cov khoom tseem ceeb no. Nws yog ib qho tseem ceeb uas yuav tsum tau siv iodine kom zoo thiab hauv qhov tsim nyog kom tsis txhob muaj teeb meem kev noj qab haus huv.
