Cov ntsiab lus

  1. Cov khoom xyaw tuaj yeem sib cais siv ntau yam txuj ci.
  2. Chromatography suav nrog kev sib cais hnyav ntawm a khov kho nruab nrab.
  3. Distillation siv qhov zoo ntawm qhov sib txawv ntawm cov ntsiab lus kub.
  4. Evaporation tshem tawm cov kua los ntawm ib qho kev daws kom tawm mus khov kho khoom.
  5. Lim cais cov khib nyiab ntawm qhov sib txawv.

Ib yam li ntawd, 7 txoj hauv kev los cais cov sib tov yog dab tsi?

Txheeb xyuas txoj hauv kev xaiv tes, Threshing, Winnowing, Sieving, Sib nqus Attraction, Sublimation, Evaporation , Crystallization, Sedimentation & Decantation, Chaw thau khoom, Lim , Distillation , Centrifugation, thiab ntawv Chromatography tuaj yeem siv tau hauv lub neej txhua hnub.

Qhov thib ob, 8 txoj hauv kev ntawm kev sib cais sib xyaw yog dab tsi? Cov ntsiab lus hauv cov teeb no (8)

  • Distillation. sib cais los ntawm boiling point sib txawv.
  • Floatation. kev sib cais ntawm cov khib nyiab los ntawm qhov sib txawv.
  • Chromatography. sib cais los ntawm sab hauv molecular attractions.
  • Magnetism.
  • Lim.
  • Kev rho tawm.
  • Crystallization.
  • Mechanical Separation.

Dab tsi yog 10 txoj hauv kev ntawm kev sib cais sib xyaw?

Qee txoj hauv kev sib cais cov tshuaj los yog sib tov yog:

  • Kev xaiv tes.
  • Khaub ncaws.
  • Winnowing.
  • Sieving.
  • Evaporation.
  • Distillation.
  • Lim los yog Sedimentation.
  • Sib cais Funnel.

Dab tsi yog qhov pov tseg ntawm kev sib cais?

Lim yog ib txoj hauv kev rau sib cais ib qho insoluble khoom los ntawm cov kua. Thaum a sib tov cov xuab zeb thiab dej yog lim: cov xuab zeb nyob tom qab ntawm daim ntawv lim (nws dhau los ua cov seem) cov dej dhau los ntawm cov ntawv lim (nws dhau los ua cov lim dej)
