Kev sib xyaw tuaj yeem sib cais los ntawm kev hloov ntawm lub cev , nrog rau cov txheej txheem xws li chromatography, distillation, evaporation, thiab lim . Kev hloov ntawm lub cev tsis hloov qhov xwm txheej, lawv tsuas hloov daim ntawv. Cov khoom ntshiab, xws li cov khoom sib txuas, tuaj yeem sib cais los ntawm tshuaj hloov pauv.
Ntxiv rau qhov no, lim dej puas hloov pauv lub cev lossis tshuaj lom neeg?
Yog tias koj siv micro lim los yog ultra lim , tsis muaj tshuaj hloov thaum lim uas tsuas yog ib lub cev txheej txheem. Cov dej Cov molecules nyob twj ywm li H2O uas yog me dua kom dhau los ntawm cov pores ntawm daim nyias nyias.
Qhov thib ob, oxidation puas yog lub cev lossis tshuaj hloov pauv? Cov tshuaj tiv thaiv no koom nrog kev hloov ntawm electrons. Loss ntawm electrons ua rau oxidation , thiab kev txo qis yog hais txog kev txais electrons. Thaum twg oxidation tshwm sim, txo kuj yuav tshwm sim. Daim ntawv ceeb toom cov hlau atoms thiab cov pa oxygen molecules ua ke los ua ib qho kev sib xyaw tshiab, uas ua rau cov tshuaj tiv thaiv no a tshuaj hloov.
Kuj kom paub yog, yog qhov pom ntawm lub cev?
Lwm qhov piv txwv rau kev siv lub cev muaj zog cais cov sib tov yog filtration (Daim duab 3.5. 4). Lim yog ib yam ntawm ntau yam mechanical, lub cev los yog kev ua haujlwm lom neeg uas cais cov khib nyiab ntawm cov kua (kua lossis roj) los ntawm kev ntxiv ib qho nruab nrab uas tsuas yog cov kua dej tuaj yeem dhau mus.
Puas yog purification yog kev hloov tshuaj?
Kev huv huv hauv a tshuaj cov ntsiab lus yog lub cev sib cais ntawm a tshuaj cov khoom ntawm kev txaus siab los ntawm txawv teb chaws los yog cov khoom paug. evaporation tshem tawm cov kua dej tsis hloov pauv los ntawm cov tshuaj tsis hloov pauv, uas tsis tuaj yeem ua los ntawm kev pom vim qhov me me ntawm cov tshuaj.

Puas yog huab cua hloov pauv lub cev lossis tshuaj lom neeg?
Kev hloov ntawm lub xeev yog kev hloov ntawm lub cev hauv qhov teeb meem. Lawv yog cov kev hloov pauv uas tsis hloov qhov teeb meem tshuaj pleev lossis tshuaj lom neeg. Piv txwv li, thaum huab cua hloov mus rau dej vapor, nws tseem yog dej thiab tuaj yeem hloov rov qab mus rau cov kua dej dua
Puas yog tshuaj lom neeg ntom ntom lossis lub cev hloov pauv?
Kev piav qhia: Cov khoom siv tshuaj lom neeg tsuas yog tsim los ntawm kev ua cov tshuaj tiv thaiv (kub ntawm combustion, flash point, enthalpies ntawm kev tsim, thiab lwm yam). Qhov ntom tuaj yeem tsim tau yooj yim los ntawm kev txiav txim siab qhov ntim ntawm cov khoom, tsis muaj kev cuam tshuam, yog li nws aphysical khoom
Puas yog hluav taws kub nyhiab yog qhov hloov pauv ntawm lub cev lossis tshuaj lom neeg?
Thaum cov roj hlawv nws feem ntau ua ke nrog oxygen kom muab cov pa roj carbon dioxide, dej thiab lwm yam nrog rau kev tso tawm ntawm lub zog. Los ntawm kev txhais, nws yog kev hloov tshuaj
Puas yog lub cev hloov pauv thaum lub zog ntxiv lossis tshem tawm?
Raws li lub zog hloov ntawm ib qho khoom mus rau lwm qhov, lub zog ntawm txhua yam khoom hloov pauv, tab sis tsis yog nws cov tshuaj pleev ib ce. Dissolving ib yam nyob rau hauv lwm yam kuj yog ib tug hloov lub cev
Puas muaj kev hloov pauv ntawm lub cev lossis tshuaj lom neeg thaum muaj suab thaj yaj hauv dej?
Dissolving qab zib hauv dej yog ib qho piv txwv ntawm kev hloov lub cev. Nov yog vim li cas: Kev hloov tshuaj lom neeg tsim cov khoom siv tshuaj tshiab. Txhawm rau kom qab zib hauv dej los ua cov tshuaj hloov pauv, ib yam tshiab yuav tsum tau ua. Yog tias koj evaporate cov dej los ntawm cov kua qab zib-dej, koj nyob nraum nrog qab zib
