Cov txheej txheem uas peb tuaj yeem ua tau cais cov particle a colloidal tshuaj hu ua Centrifugation.
Cov lus nug tseem yog, koj puas tuaj yeem lim cov colloid?
Colloids tsis zoo li cov kev daws teeb meem vim tias lawv cov khoom tawg yooj yim ntau dua li cov kev daws teeb meem. Dispersed particles ntawm a colloid tsis tuaj yeem sib cais los ntawm lim , mas lawv tawg lub teeb, ib qho tshwm sim hu ua Tyndall effect.
Tsis tas li ntawd, dab tsi yog qhov kev daws teeb meem colloidal? Colloidal daws , los yog colloidal suspensions, tsis muaj dab tsi tab sis yog ib qho kev sib xyaw uas cov tshuaj raug ncua tsis tu ncua hauv cov kua dej. A colloid yog ib yam khoom me me thiab me me uas kis tau zoo ib yam los ntawm lwm cov khoom. Txawm li cas los xij, a colloidal tshuaj feem ntau yog hais txog cov kua ua kua.
Raws li, koj yuav cais cov kev daws teeb meem li cas?
Distillation siv boiling rau cais sib tov ua kua kev daws teeb meem . Nws yuav siv sij hawm rau hauv tus account tias cov khoom sib txawv hauv qhov sib tov yuav muaj cov ntsiab lus sib txawv. Piv txwv li, yog tias koj rhaub dej ntsev hauv cov dej daws yuav boil ua ntej ntsev. Tom qab ntawd cov dej yuav evaporate tawm cov ntsev qab.
Cov txheej txheem twg yog siv los cais cov khoom ntawm colloids?
Colloids tsis tuaj yeem sib cais los ntawm kev sib tov los ntawm cov txheej txheem ntawm lim . Tab sis, cov txheej txheem tshwj xeeb ntawm kev sib cais hu ua centrifugation tuaj yeem siv los cais cov colloidal hais.
