Alumina (A/B/N)Alumina m lokaci hakar ginshiƙi/SPE shafi

Alumina ne na hali Lewis acid, Alumina atom cibiyar rasa biyu electrons. Yana da adsorbent mai ƙarfi mai ƙarfi, mai kama da na silicone, Akwai matakan manyan ayyuka uku na acidity, alkalinity da tsaka tsaki; Alumina kuma yana da tasiri na musamman akan theπelectrons of aromatic hydrocarbons, Ya fi silicone a high pH yanayi. Babban hanyoyin riƙewa sune lewis acid/aikin tushe, polarity da musayar ion.

Acid acidAbubuwan lewis acid na alumina-A (pH = 4.5) an haɓaka su, Irin wannan adsorbent yana da mafi kyawun riƙewa ga mahaɗan lantarki masu wadata. Bugu da kari, a lokacin da pretreatment tare da acidic bayani, da adsorbent yana da rauni cationic Properties, da surface ne mafi kusantar su riƙe tsaka tsaki da kuma mummunan cajin abubuwa (kamar electroneutral ko acidic anions), Ba za a iya ci gaba da m cajin. The rauni ion musayar dukiya. Hakanan yana sauƙaƙa riƙe kayan caji mara kyau.

Alumina na asaliAn fi son saman Alumina-B (pH=10) don riƙe ko dai tabbatacce ko hydrogen - kayan haɗin gwiwa. Aluminum oxide bi da tare da alkaline bayani yana da anionic Properties da cationic musayar aiki. Bugu da kari, ko da yake saman yana da halaye na Lewis tushe, ana iya riƙe shi don samfurin lantarki, kamar mahaɗan amine tsaka tsaki. Ƙarfin yana da ƙasa da ƙasa don tsaka tsaki da alumina acidic. Bugu da ƙari, ana iya samun haɗin haɗin hydrogen mai ƙarfi akan alumina-b, don haka tasirin samfurin cationic na iyakacin duniya shima a bayyane yake.

Alumina tsaka tsakiAlumina-N (pH = 7.5) kuma yana da ƙarfin polar adsorbent. A ƙarƙashin yanayin babban pH, alumina ya fi kwanciyar hankali fiye da na ƙungiyar aikin da ba a haɗa ba. Finer barbashi tabbatar da kyau hakar yadda ya dace, don haka karamin size cylindrical gado (50mg) ne mafi yawan amfani da samfurin. Adsorbent yana tsaka tsaki na lantarki kuma yana kula da riƙe wadatattun mahadi na lantarki kamar su amines masu ƙanshi da fatty. A lokaci guda kuma, akwai kuma ikon riƙe mahadi masu ɗauke da ƙungiyoyin lantarki kamar su oxygen-dauke da atom, phosphorous da sulfur. Ana iya amfani da Alumina-N don hakar da rabuwa na polar ko abubuwan da ba na igiya ba a cikin ruwa mai narkewa da samfurori marasa ruwa.
