Alumina (A/B/N)Alumina ri to alakoso isediwon iwe / SPE iwe
Alumina jẹ aṣoju Lewis acid, Ile-iṣẹ atomu aluminiomu ko ni awọn elekitironi meji. O ni adsorbent pola ti o lagbara, iru si ti silikoni, Awọn ipele iṣẹ ṣiṣe giga mẹta ti acidity, alkalinity ati didoju; Alumina tun ni ipa pataki lori theπelectrons ti awọn hydrocarbons aromatic, O dara julọ ju silikoni ni awọn ipo pH giga. Awọn ilana idaduro akọkọ jẹ Lewis acid / igbese ipilẹ, polarity ati paṣipaarọ ion.
Alumina acidAwọn ohun-ini lewis acid ti alumina-A (pH = 4.5) ti mu dara si, Iru adsorbent yii ni idaduro to dara julọ fun awọn agbo ogun elekitironi ọlọrọ. Ni afikun, nigba ti iṣaju pẹlu ojutu ekikan, adsorbent ni awọn ohun-ini cationic ti ko lagbara, dada jẹ diẹ sii lati ṣe idaduro didoju ati awọn nkan ti o gba agbara ni odi (gẹgẹbi eleto tabi awọn anions acidic), Ko le tọju idiyele rere. Ohun-ini paṣipaarọ ion ti ko lagbara. tun jẹ ki o rọrun lati ṣe idaduro ohun elo idiyele odi.
Alumina ipilẹIlẹ ti Alumina-B(pH=10) jẹ ojurere lati daduro boya rere tabi hydrogen – awọn ohun elo ti o ni asopọ. Aluminiomu oxide ti a tọju pẹlu ojutu ipilẹ ni awọn ohun-ini anionic ati iṣẹ paṣipaarọ cationic. Ni afikun, botilẹjẹpe dada ni awọn abuda ti ipilẹ Lewis, o le wa ni idaduro fun apẹẹrẹ elekitironi, gẹgẹbi awọn agbo ogun amine didoju. Agbara jẹ kekere pupọ fun didoju ati alumina ekikan. Ni afikun, asopọ hydrogen to lagbara ni a le rii lori alumina-b, nitorinaa ipa ti apẹẹrẹ cationic pola tun han gbangba.
Alumina aiduroAlumina-N(pH=7.5) tun jẹ adsorbent pola to lagbara. Labẹ ipo ti pH giga, alumina jẹ iduroṣinṣin diẹ sii ju ti ẹgbẹ iṣẹ ṣiṣe ti ko ni adehun. Awọn patikulu ti o dara julọ ṣe idaniloju ṣiṣe isediwon ti o dara, nitorinaa ibusun iwọn kekere kan (50mg) jẹ ọja ti a lo julọ. Adsorbent jẹ didoju itanna o si duro lati daduro awọn agbo itanna eletiriki ọlọrọ gẹgẹbi aromatic ati amines ọra. Ni akoko kanna, agbara tun wa lati ṣe idaduro awọn agbo ogun ti o ni awọn ẹgbẹ elekitironi gẹgẹbi atẹgun ti o ni, phosphorous ati awọn ọta imi-ọjọ. Alumina-N le ṣee lo fun isediwon ati iyapa ti pola tabi ti kii-pola oludoti ni omi-tiotuka ati ti kii-olomi awọn ayẹwo.
