Alumina (A / B / N) Alumina marxaladda adag column saaridda / column tageysaa

Alumina waa a acid caadiga Lewis, xarunta la eb aluminium waxaa ka maqan labo electrons. Waxay leedahay adsorbent si xoog leh kala horjeeda, mid ah in silicone, Waxaa jira saddex heer oo waxqabad sare ee aysidhka, alkalinity iyo dhexdhexaadnimada; Alumina sidoo kale waxay leedahay saamayn gaar ah ku theπelectrons ee Consort leedahay beduliyum, Waa ka wanaagsan yahay silicone xaalado pH sare. The hababka ugu muhiimsan haynta yihiin Lewis tallaabo acid / saldhiga, polarity iyo is-dhaafsiga ra'iyi.

Acid alumina guryaha The Lewis acid of alumina-A (pH = 4.5) ayaa wanaajiyey, noocan ah adsorbent leeyahay haynta wanaagsan ee xeryahooda electron hodan. Intaa waxaa dheer, marka pretreatment xal acidic, adsorbent ku leeyahay sifooyin cationic daciif ah, dusha sare u badan tahay in hayn walxaha dhexdhexaad ah oo si xun u eedeeyay (sida anions electroneutral ama acidic), ma haysan karaa charge.The wanaagsan ra'iyi daciif hantida sarrifka a sidoo kale waxay sahlaysaa in la hayn wax kharash xun.

Alumina aasaasiga ah dusha ah ee Alumina B (pH = 10) waxaa ka fadilay in ay sii haystaan mid togan ama hydrogen - qalabka addoonsi. Xabagta Aluminum loola dhaqmo si xal xumadoodu wuxuu leeyahay sifooyin anionic iyo shaqada sarrifka cationic. Intaa waxaa dheer, in kasta oo dusha sare ay leedahay sifooyinka saldhigga Lewis, waxaa la hayn karaa tusaale electron ah, sida xeryahooda abahaaga dhexdhexaad ah. Awoodda aad uga yar for alumina dhexdhexaad iyo acidic. Intaa waxaa dheer, bond hydrogen xoog leh waxaa laga heli karaa on the alumina-b, sidaas saamaynta saamiga horjeeda cationic sidoo kale waa wax iska cad.

Alumina dhexdhexaad Alumina-N (pH = 7.5) sidoo kale waa adsorbent ah si xoog leh kala horjeeda. Under xaaladda pH sare, alumina waa deganaanshaha badan in kooxda unbonded functional. Qurub qaadhaan loo hubiyo tayada shaqo ka fiirsato wanaagsan, sidaas a size yar sariirta cylindrical (50mg) waa wax soo saarka ugu badan ee la isticmaalo. Adsorbent waa koronto dhexdhexaad iyo hidde u hayn xeryahooda electronic hodan sida amines leedahay beduliyum iyo dufan. Isla mar ahaantaa, waxaa sidoo kale waa awood u leeyahay inuu xajisto xeryahooda ka kooban kooxaha electronegative sida oxygen-ka kooban, phosphorous iyo baaruud atamka. Alumina-N loo isticmaali karaa saaridda iyo kala walxaha kala horjeeda ama non-horjeeda in baarka biyo-L iyo kuwa aan aqueous.
