Ialumina(A/B/N)Ikholamu yesigaba se-alumina esiqinileyo / ikholamu ye-SPE

I-alumina yi-asidi ye-lewis eqhelekileyo, Iziko le-athomu ye-aluminiyam ayinazo ii-electron ezimbini.Ine-polar adsorbent enamandla, efana ne-silicone, Kukho amanqanaba amathathu aphezulu omsebenzi we-asidi, i-alkalinity kunye nokungathathi hlangothi;I-alumina nayo inempembelelo ekhethekileyo kwi-elektroni ye-aromatiki yee-hydrocarbons, Ingcono kune-silicone kwiimeko eziphezulu ze-pH.Iindlela zokugcina eziphambili ziyi-lewis acid / isenzo sesiseko, i-polarity kunye ne-ion exchange.

Iasidi yealuminaIimpawu ze-asidi ze-lewis ze-alumina-A (pH = 4.5) zaphuculwa, Olu hlobo lwe-adsorbent lunokugcinwa okungcono kwiikhompawundi ze-electron ezityebileyo.Ukongeza, xa unyango lwangaphambili kunye nesisombululo esine-acidic, i-adsorbent ineempawu ezibuthathaka ze-cationic, umphezulu kunokwenzeka ukuba ugcine izinto ezingathathi hlangothi kunye nezibi (ezifana ne-electroneutral okanye i-anion acidic), Ayikwazi ukugcina intlawulo efanelekileyo.Ipropati yokutshintshiselana nge-ion ebuthathaka. kwenza kube lula ukugcina imathiriyeli yentlawulo embi.

I-alumina esisisekoUmphezulu we-Alumina-B (pH=10) uthandwa ukugcina nokuba yi-positive okanye i-hydrogen - imathiriyeli edibeneyo.I-aluminium oxide iphathwe ngesisombululo se-alkaline ineempawu ze-anionic kunye nomsebenzi wokutshintshiselana kwe-cationic.Ukongeza, nangona umphezulu uneempawu zesiseko se-lewis, unokugcinwa kwisampuli ye-electron, njenge-neutral amine compounds.Ikhono lisezantsi kakhulu kwi-alumina engathathi hlangothi kunye ne-acidic.Ukongeza, i-hydrogen bond eyomeleleyo inokufumaneka kwi-alumina-b, ngoko ke umphumo wesampulu ye-polar cationic nayo icacile.

I-alumina engathathi hlangothiI-Alumina-N(pH=7.5) ikwasisibhengezo esinamandla sepolar.Ngaphantsi kwemeko ye-pH ephezulu, i-alumina izinzile ngakumbi kuneqela elingasebenziyo elingasebenziyo.Iincinci ezincinci ziqinisekisa ukusebenza kakuhle kokutsalwa, ngoko ke ibhedi encinci ye-cylindrical (50mg) iyona mveliso isetyenziswa ngokuqhelekileyo.I-adsorbent ayithathi hlangothi ngokombane kwaye ikholisa ukugcina iikhompawundi ezityebileyo ze-elektroniki ezifana ne-aromatics kunye ne-fatty amines.Kwangaxeshanye, kukho ukukwazi ukugcina iikhompawundi eziqulethe amaqela e-electronegative afana ne-oxygen-containing, i-phosphorous kunye neeathom zesulfure.I-Alumina-N ingasetyenziselwa ukutsalwa kunye nokwahlula izinto ze-polar okanye ezingekho-polar kwiisampuli zamanzi ezinyibilikayo nezingamanzi.

Iinzuzo zemveliso:
