Kev ua yuam kev thaum lub sij hawm rho tawm (piv txwv li nqa nrog qhov tsis ncaj ncees lawm txheej ), tuaj yeem daws tau yog tias cov kev daws teeb meem tsis tau muab tso rau hauv lub thawv pov tseg! Cov txheej yuav tsum tau txais kev cawmdim mus txog thaum tom qab evaporation vim hais tias qhov xav tau compound yuav tsis soluble heev nyob rau hauv cov kuab tshuaj siv.

Tom qab ntawd, vim li cas ntau qhov kev rho tawm zoo dua?

Yog li nrog ntau extraction tus nqi ntawm cov khoom nyob rau hauv cov residue yuav qis dua, ergo lub rho tawm yuav yog ntau ua kom tiav. Ob peb rho tawm nrog me me ntim ntawm cov kuab tshuaj yog zoo dua tshaj ib leeg rho tawm nrog ib tug loj ntim ntawm hnyav.

Tsis tas li ntawd, lub hom phiaj ntawm kev rho tawm nrog cov ntim me me ntawm cov kuab tshuaj ntau zaus yog dab tsi? Hauv ib ntau extraction txheej txheem, kom muaj nuj nqis kuab tshuaj yog siv rau rho tawm ib txheej (feem ntau yog txheej aqueous) ntau zaus ua ke. Cov rho tawm rov ua dua ob mus rau peb sij hawm , los yog tej zaum ntau dua sij hawm Yog hais tias lub compound muaj ib tug tsawg partition coefficient nyob rau hauv cov organic kuab tshuaj.

Nyob rau hauv no txoj kev, thaum siv ib tug cais funnel uas yuav tsum tau muab pov tseg?

Hauv qab txheej yog xa rov qab rau funnel thiab cov txheej txheem rho tawm txuas ntxiv mus. -Tsis txhob muab pov tseg thiab txheej kom txog thaum lub extraction tiav thiab koj yeej paub tseeb tias koj muaj qhov tseeb txheej . - Extracting nrog ob peb qhov me me ua tau zoo dua nrog ib loj.

Vim li cas qhov kev sib cais funnel ua rau lub siab?

Cov txhim kho ntawm siab tshwm sim vim ib feem ntawm cov kuab tshuaj vaporizes thaum lub cais funnel yog shaken. Cov menyuam kawm ntawv uas mob siab rau yuav pom tias thaum cov kuab tshuaj muaj dej tsawg heev siab buildup tshwm sim.
