Sib cais los ntawm hnoos tawm Extraction

Kev taw qhia

Cov compound yog kis los ntawm ib qho hnyav rau lwm qhov siv qhov sib txawv ntawm kev daws teeb meem los sis kev faib coefficient ntawm lub compound hauv ob leeg tsis sib haum xeeb (los sis me ntsis soluble) cov tshuaj solvents.Thaum rov qab cov extractions, feem ntau ntawm cov tebchaw yog muab rho tawm.

Tseem ceeb

Txoj kev extraction yog xws li cov organic theem thiab cov aqueous theem sib xyaw nrog txhua lwm yam, thiab cov khoom yuav tsum tau sib cais hauv cov aqueous theem nkag cov organic theem, thiab tom qab ntawd ces ob theem raug sib cais los ntawm qhov ntau ntawm cov theem ob. Cov organic theem feem ntau muaj peb cov khoom, namely tus extractant, ib diluent, thiab ib tug solvent.Tej zaum qee tus modifiers ntxiv rau lub extractant ua tus extractant ua tau zoo dua.Qhov extraction ntawm non-ferrous hlau cyanide ntawm cyanide kua yog feem ntau tawm los ntawm kev siv polymer organic amine xws li trialkylmethylamine chloride (N263), ib qho dej cawv ntau dua, thiab hnyav ua sulfonated kerosene.Qhov theem aqueous yog cov dej khib nyiab kho.

Daim ntawv thov

Solvent extraction yog dav siv nyob rau hauv lub metallurgical thiab tshuaj industries.In qhov kev lag luam kub, muaj ntau cov kev tshawb fawb ntawm extracting dawb ntshiab thiab nyiaj los ntawm kuab extraction.
