Alumina (ABN) SPE
Alumina (A / B / N)Alumina khoom theem rho tawm kem / SPE kem
Alumina yog ib tug raug lewis acid, Aluminium atom center tsis muaj ob electrons.Nws muaj zog polar adsorbent, zoo ib yam li cov silicone, Muaj peb theem kev ua haujlwm siab ntawm acidity, alkalinity thiab neutrality;Alumina kuj muaj cov nyhuv tshwj xeeb rau cov π electrons ntawm cov pa roj carbon monoxide, Nws zoo dua li silicone nyob rau hauv siab pH.Lub ntsiab tuav mechanisms yog lewis acid / puag nkaus, polarity thiab ion pauv.
Acid aluminaLub lewis acid zog ntawm alumina-A (pH = 4.5) tau txhim kho, Qhov no adsorbent muaj kev tuav pov hwm zoo dua rau cov nplua nuj electron tebchaw.Tsis tas li ntawd, thaum pretreatment nrog acidic tov, cov adsorbent muaj zog cationic zog, qhov saum npoo yog feem ntau yuav khaws cov nruab nrab thiab tsis zoo nqi (xws li electroneutral los yog acidic anions), Tsis tau khaws ib tug zoo xwb.Qhov tsis muaj zog ion pauv khoom. kuj ua rau nws yooj yim dua khaws cov khoom tsis zoo.
Basic aluminaQhov saum npoo ntawm Alumina-B (pH = 10) tau txais kev pom zoo los khaws cov khoom zoo lossis hydrogen - cov khoom sib txuas.Aluminium oxide kho nrog alkaline kua muaj anionic zog thiab cationic pauv muaj nuj nqi.Tsis tas li ntawd, txawm hais tias qhov chaw muaj cov yam ntxwv ntawm lewis puag, nws tuaj yeem khaws cia rau cov qauv siv hluav taws xob, xws li nruab nrab amine compounds.Lub peev xwm yog qis dua rau nruab nrab thiab acidic alumina.Tsis tas li ntawd, muaj zog hydrogen daim ntawv cog lus tuaj yeem pom ntawm alumina-b, yog li cov nyhuv ntawm cov qauv polar cationic kuj pom tseeb.
Nruab nrab aluminaAlumina-N (pH = 7.5) kuj yog ib qho adsorbent zoo heev.Nyob rau hauv cov xwm txheej ntawm pH siab, alumina yog ruaj khov dua li ntawm cov pab pawg neeg tsis muaj zog.Finer hais kom zoo extraction efficiency, yog li me me cylindrical txaj (50mg) yog cov khoom siv feem ntau.Cov adsorbent yog hluav taws xob nruab nrab thiab nyiam khaws cov khoom siv hluav taws xob nplua nuj xws li cov ntxhiab tsw thiab cov roj amines.Nyob rau tib lub sijhawm, tseem muaj peev xwm khaws cov tebchaw uas muaj cov pab pawg electronegative xws li cov pa oxygen, phosphorous thiab sulfur atoms.Alumina-N tuaj yeem siv rau kev rho tawm thiab sib cais ntawm cov polar lossis tsis-polar hauv cov dej-soluble thiab tsis-aqueous qauv.
