Qhov sib txawv tseem ceeb ntawm kev sib cais thiab kev ua kom huv yog kev sib cais yog kev hloov pauv ntawm cov khoom sib xyaw rau hauv ob lossis ntau dua cov khoom lossis kev sib xyaw ntawm cov khoom whereas purification yog tshem tawm cov kab mob ntawm cov qauv tshuaj ntsuam.
Kev sib cais thiab kev ua kom huv yog ob yam txheej txheem hauv kev tshuaj ntsuam chemistry; Kev sib cais tuaj yeem siv rau kev ua kom huv huv.
Kev sib cais yog dab tsi?
Kev sib cais yog kev hloov pauv ntawm cov khoom sib xyaw rau hauv ob lossis ntau qhov sib txawv ntawm cov khoom sib xyaw. Thaum lub sij hawm sib cais, tsawg kawg yog ib qho ntawm cov khoom sib xyaw hauv qhov sib tov yog concentrated nyob rau hauv qhov kawg tshwm sim. Qee zaum, txoj kev sib cais tuaj yeem faib qhov sib xyaw ua ke rau hauv nws cov khoom ntshiab. Tsis tas li ntawd, kev huv huv yog ib hom kev sib cais tshwj xeeb uas peb tuaj yeem cais thiab cais cov khoom xav tau los ntawm kev sib xyaw ntawm cov khoom sib xyaw. Qhov tseem ceeb, kev sib cais ntawm qhov sib tov tuaj yeem siv qhov sib txawv ntawm cov tshuaj lom neeg thiab lub cev ntawm cov khoom sib xyaw.
Ntxiv mus, cov txheej txheem sib cais feem ntau tau muab cais raws li qhov sib txawv tshwj xeeb uas cov txheej txheem siv rau kev ua tiav ntawm cov khoom sib cais. Txawm li cas los xij, yog tias tsis muaj qhov sib txawv tshwj xeeb ntawm cov khoom sib xyaw ua ke, peb yuav tau siv ntau txoj haujlwm ua ke nrog ib leeg kom tau txais cov khoom kawg uas xav tau.
Feem ntau, cov tshuaj lom neeg thiab feem ntau ntawm cov khoom sib txuas tshwm sim hauv lub xeev tsis huv. Yog li ntawd, peb tuaj yeem cais cov khoom xav tau lossis cov khoom sib txuas los ntawm lawv qhov chaw (ore) thiab ua cov txheej txheem sib cais ua ntej cov khoom tuaj yeem muab tso rau hauv kev tsim khoom. Yog li, qhov no ua rau kev sib cais tseem ceeb rau kev lag luam niaj hnub no.
Daim duab 01: Flotation Technique – Ib Hom Kev Sib Cais
Feem ntau, lub hom phiaj ntawm kev sib cais yog kev tshuaj xyuas. Tab sis qee zaum, nws yog qhov npaj tau thaum peb tuaj yeem npaj cov feem sib txawv ntawm cov qauv ntsuas rau kev siv ntxiv. Ntxiv mus, peb tuaj yeem ua cov txheej txheem sib cais hauv me me lossis hauv cov nplai loj (piv txwv li kev lag luam nplai).
Kev Purification yog dab tsi?
Kev huv yog ib qho txheej txheem tshuaj xyuas uas peb tuaj yeem cais cov kab mob ntawm cov khoom xav tau. Nyob rau hauv lwm yam lus, purification yog tus txheej txheem ntawm rendering ib yam dab tsi ntshiab. Nws yog lub cev sib cais ntawm cov tshuaj lom neeg ntawm kev txaus siab los ntawm cov khoom sib kis. Peb tuaj yeem muab lub npe dawb huv ntawm kev ua kom huv huv ua tiav raws li "kev cais tawm".
Ntxiv mus, muaj ntau txoj kev ua kom huv huv uas peb tuaj yeem siv hauv chemistry nyob ntawm lub hom phiaj thiab daim ntawv thov; Qee qhov piv txwv muaj xws li affinity purification, filtration, centrifugation, evaporation, extraction, crystallization, recrystallization, adsorption, chromatography, smelting, refining, etc.
Qhov txawv ntawm kev sib cais thiab kev huv yog dab tsi?
Kev sib cais thiab kev ua kom huv yog ob yam txheej txheem hauv kev tshuaj ntsuam chemistry uas sib cais tuaj yeem siv rau cov txheej txheem purification. Qhov sib txawv tseem ceeb ntawm kev sib cais thiab kev ua kom huv yog tias kev sib cais yog kev hloov pauv ntawm cov khoom sib xyaw rau hauv ob lossis ntau dua cov khoom lossis kev sib xyaw ntawm cov khoom whereas purification yog tshem tawm cov kab mob los ntawm cov qauv tshuaj ntsuam xyuas. Tsis tas li ntawd, kev sib cais muaj cov txheej txheem xws li chromatography, electrophoresis, flotation, extraction, thiab lwm yam. Thaum purification muaj affinity purification, pom, chromatography, adsorption, extraction, thiab lwm yam.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm kev sib cais thiab kev huv hauv daim ntawv teev npe.
Summary – Sib cais vs Purification
Nyob rau hauv qhov tseem ceeb, kev sib cais thiab kev ua kom huv yog ob yam txheej txheem hauv kev tshuaj ntsuam chemistry qhov kev sib cais tuaj yeem siv rau kev ua kom huv. Qhov sib txawv tseem ceeb ntawm kev sib cais thiab kev ua kom huv yog tias kev sib cais yog kev hloov pauv ntawm cov khoom sib xyaw rau hauv ob lossis ntau dua cov khoom lossis cov khoom sib xyaw, qhov kev ua kom huv yog tshem tawm cov kab mob ntawm cov qauv tshuaj ntsuam xyuas.
