Thaum kev soj ntsuam seb puas tsim nyog thaum siv kev sib cais funnel, nws yog qhov tseem ceeb kom nkag siab txog kev ua haujlwm thiab cov kev siv sib cais ntawm ob qho chaw nres tsheb thiab cov nres tsheb.
Ib qho chaw nres tsheb, ntawm qhov tod tes, yog lub pob hluav taws xob siv los tswj cov dej ntws (kua lossis roj av) hauv kev kuaj. Nws yog feem ntau yog lub teb chaws teb teb nrog ib threaded ntsaws uas tuaj yeem kaw kom nruj kom tiv thaiv tsis taus. Cov neeg nres tsheb tsis muaj ntau zaus pom ntawm ntau daim iav iav, suav nrog kev sib cais nrog kev tswj hwm kom meej ntawm kev tso dej tawm.
Qhov yuav tsum tau ntawm kev nres tsheb hauv kev sib cais funnel
Tswj cov kua ntws
Qhov muaj txiaj ntsig zoo tshaj plaws ntawm muaj nres ntawm kev sib cais funnel yog lub peev xwm los tswj cov dej ntws. Qhov no yog ib qho tshwj xeeb tshaj yog thaum lub sij hawm ua kua ua kua, qhov uas koj yuav xav tau maj mam tso cov kua qis dua tsis muaj kev cuam tshuam rau txheej sab saud.
Kev tiv thaiv ntawm kev txeej
Nrog nres nres, koj tuaj yeem yooj yim nres cov kua dej yog tias tsim nyog, tiv thaiv spills thiab kev tswj hwm qhov chaw huv. Qhov no yog qhov tseem ceeb tshwj xeeb thaum cuam tshuam nrog cov tshuaj phom sij.
Yooj yim ntawm kev ua haujlwm
Txoj kev nres tsheb yog qhov yooj yim kom ntws lub funnel yam tsis tas yuav qhia nws lossis siv nws tus kheej, uas tuaj yeem yog kev ntxhov siab thiab tsis muaj tseeb.
Kev xaiv yam tsis muaj nres
Thaum lub sijhawm nres yog qhov feem ntau thiab yooj yim los tswj kev ntws ntawm cov kua los ntawm kev sib cais funnel, muaj lwm yam:
Age Los txhais phau ntawv cia li: Qee qhov sib cais kev lom zem yuav muaj qhov caj dab yooj yim uas tso cai rau koj kom siv cov kua tawm. Txawm li cas los xij, hom no tsis tshua meej thiab tuaj yeem ua tsis tau.
● Tipping: Lwm txoj kev xaiv yog los ua kom yooj yim lub funnel mus nchuav tawm cov kua. Cov qauv no tsis muaj qhov tseeb thiab tswj, thiab tuaj yeem ua rau cov khoom nchuav.
Nyob rau hauv xaus, thaum nws muaj peev xwm siv tus sib cais funnel yam tsis muaj kev txiav tawm, kev sib ntxiv, thiab yooj yim ntawm kev ua haujlwm ua kua. Nws tso cai rau kev tso tawm cov kua roj ntau ntxiv, tiv thaiv cov khoom nchuav, thiab tswj hwm kev ua haujlwm huv thiab nyab xeeb. Yog li ntawd, hauv cov chaw kuaj xyuas feem ntau, kev sib cais funnel nrog lub txiav luam yeeb yog qhov kev xaiv uas nyiam tshaj plaws rau cov kua dej ua kua.
TxogKua-kua extraction
Ua kua ua kua extraction, tseem hu ua cov kuab tshuaj extraction, yog ib qho kev daws teeb meem uas yog ib theem ua kua (feem ntau yog cov aqu aqu agent) raws li lawv cov neeg txheeb ze ua haujlwm hauv ob ntu. Cov txheej txheem no tau ua haujlwm hauv ntau daim teb xws li analaltical chemistry, ib puag ncig science, kev lag luam ib puag ncig, kev lag luam kws tshuaj, thiab kev sib cais.
Cov ntsiab cai
Lub hauv paus ntsiab lus hauv qab dej-kua extraction yog lub solubility qhov sib txawv ntawm cov duab sib txawv. Thaum ob lub kua dej cuav (piv txwv li, lawv tsis sib tov nrog lwm tus) tau coj mus rau hauv ib qho kua tuaj yeem sib faib ntawm ob ntu raws li lawv nyiam solubility. Kev faib tawm cov tebchaw ntawm ob theem yog tswj hwm los ntawm cov kev faib tawm coefficient, uas yog kev ntsuas ntawm qhov sib xyaw ntawm ob ntu ntawm ob peb theem ntawm kev sib npaug.
Hom
Ib theem zuj zus
Hauv hom no, ib kauj ruam extraction yog ua qhov twg cov kua a aqueous uas muaj cov sib xyaw ntawm cov kev txaus siab yog tov nrog cov kuab tshuaj organic. Tom qab tso cai ob theem sib cais, cov kev xav tau muaj cov kev xav tau muaj nyob hauv ib qho ntawm theem.
Ntau-theem
Rau kev sib cais ntau dua, ntau cov qib kev tshem tawm tuaj yeem ua haujlwm. Nyob rau hauv txhua theem, theem aqueous yog hu nrog tshiab lossis siv cov organic tshiab, thiab cov txheej txheem rov qab ua tiav kom txog thaum muaj kev sib cais.
Countercurrent
Cov qauv no cuam tshuam nrog cov dej ntws tsis tu ncua thiab cov theem tshwm sim hauv cov lus qhia rov qab. Qhov no ua tau lub sijhawm sib cuag nyob nruab nrab ntawm ntu thiab txhim kho txoj kev ua haujlwm ntawm extraction.
