Tshuaj impurity sib cais, kev npaj thiab kev pom zoo kev pab cuam
Impurities nyob rau hauv cov tshuaj yog ze ze rau qhov zoo, kev ruaj ntseg thiab stability ntawm cov tshuaj.Kev npaj thiab qauv kev lees paub ntawm impurities hauv cov tshuaj tuaj yeem pab peb nkag siab txog txoj hauv kev ntawm impurities thiab muab lub hauv paus rau kev txhim kho cov txheej txheem ntau lawm.Yog li ntawd, kev npaj thiab kev sib cais ntawm impurities yog qhov tseem ceeb heev rau kev tshawb fawb txog tshuaj thiab kev loj hlob.
Txawm li cas los xij, cov ntsiab lus ntawm impurities nyob rau hauv cov tshuaj yog tsawg, lub hauv paus yog dav, thiab cov qauv yog feem ntau zoo ib yam li lub hauv paus ntsiab lus.Dab tsi tshuab siv tau los cais thiab ntxuav tag nrho cov impurities hauv cov tshuaj ib los ntawm ib qho thiab sai sai?Cov txheej txheem thiab cov txheej txheem twg yog siv los lees paub cov qauv ntawm cov impurities no?Qhov no yog qhov nyuaj thiab kev sib tw uas tau ntsib los ntawm ntau lub chaw muag tshuaj, tshwj xeeb tshaj yog cov chaw muag tshuaj ntawm cov tshuaj cog thiab tshuaj suav patent.
Raws li cov kev xav tau zoo li no, lub tuam txhab tau tsim cov tshuaj impurity cais thiab purification cov kev pab cuam.Relying ntawm nuclear magnetic resonance, huab hwm coj spectrometry thiab lwm yam khoom siv thiab thev naus laus zis, lub tuam txhab tuaj yeem txheeb xyuas cov qauv ntawm cov khoom sib cais, kom ua tau raws li cov kev xav tau ntawm cov neeg siv khoom.
