Txiv hmab txiv ntoo lub plhaub ua haujlwm carbon, raws li ib qho tseem ceeb adsorption cov khoom, yog siv dav hauv kev kho dej, huab cua, thiab kev decolorization. Txhawm rau kom nws ruaj khov ua haujlwm thiab txhim khu kev qha zoo, yog ib qho kev xeem tshawb fawb yog qhov tseem ceeb. Cov kab lus no paub cov kauj ruam tseem ceeb sim ua rau txiv hmab txiv ntoo ua haujlwm carbon, muab ib qho siv rau kev lag luam.
Ua ntej, pom kev pom zoo yog cov kauj ruam tseem ceeb. Los ntawm kev tshuaj xyuas kev pom, cov kev ua kom muaj zog roj teeb, xim, thiab cov ncauj lus tsis sib xws yog tshuaj xyuas kom ua raws li cov qauv. Kev txheeb xyuas me me loj yog ua, siv sieving lossis laser infalle loj kws faib khoom thiab ntsuas nws cov haum.
Iodine tus nqi xeem yog qhov taw qhia tseem ceeb ntawm kev ua haujlwm ntawm cov pa roj carbon tau ua tiav. Los ntawm reacting cov pa roj carbon ua haujlwm nrog iodine tov, tus nqi ntawm iodine adsorbed ib chav tsev loj tau suav; Tus nqi siab dua qhia tau kev ua kom muaj kev ua tiav kev ua tiav. Methylene Blue Adsorption Nqe Kev Xeem kuj tseem yog qhov tseem ceeb, ntsuas nws cov adsorption muaj peev xwm rau cov organic molecules.
Kev ya raws thiab cov hmoov tshauv cov ntsiab lus kuaj xyuas ncaj qha cuam tshuam cov kev ua haujlwm ntawm cov carbon actived. Cov ntsiab lus noo yog txiav txim los ntawm ziab kom ntseeg tau cov tshuab ziab khaub ncaws; Tshauv cov ntsiab lus cuam tshuam cov ntsiab lus ntawm inorganic impurities thiab feem ntau ntsuas los ntawm high- kub ignition. Kev ntsuas lub zog ntsuas cov pa roj carbon ua kom tsis kam mus rau qhov kev thauj mus los thiab siv, tiv thaiv kev cuam tshuam thiab ua rau muaj kev cuam tshuam.
Thaum kawg, pH ntsuas xyuas cov pa roj carbon acidentic acidentic thiab alkalinity ntsib daim ntawv thov yuav tsum muaj, feem ntau txiav txim siab txog dej tawm. Hauv qee cov ntawv thov, kev sim ntsuas cov ntsiab lus hlau kuj yuav tsum tau ua kom ntseeg tau tias ib puag ncig kev nyab xeeb.
Hauv cov ntsiab lus, cov txheej txheem ntsuas rau cov txiv hmab txiv ntoo ua haujlwm pab ntau yam, suav nrog muaj peev xwm siv lub cev, muaj peev xwm adsorption, thiab tshuaj lom neeg. Cov qauv kev sim nruj me me yog qhov tseem ceeb rau kev ua kom tiav nws cov ntawv thov ua tau zoo. Qhov kev lag luam yuav tsum tsis tu ncua kev ua kom tau cov kev sim ua kom zoo dua los txhim kho cov khoom lag luam roj carbon accon.
