Alumina(A/B/N)Alumina yakasimba chikamu chekuwedzera chikamu / SPE column

Alumina ndiyo yakajairika lewis acid, Iyo aluminium atomu centre haina maerekitironi maviri. Iyo ine yakasimba polar adsorbent, yakafanana neiyo silicone, Kune matatu akakwira basa mazinga e acidity, alkalinity uye kusarerekera; Alumina zvakare ine yakakosha mhedzisiro paπelectrons yeanonhuhwirira hydrocarbons, Zviri nani pane silicone mune yakakwirira pH mamiriro. Iwo mahombe ekuchengetedza maitiro ndeye lewis acid / base chiito, polarity uye ion exchange.

Acid aluminaIyo lewis asidhi zvimiro zvealumina-A (pH = 4.5) zvakakwidziridzwa, Rudzi urwu rweadsorbent rune kuchengetedza zvirinani kune akapfuma erekitironi makomisheni. Uyezve, kana pretreatment ane acidic mhinduro, adsorbent ane utera cationic zvivako, pamusoro zvingangoita kuchengeta kwazvakarerekera uye zvakaipa chaja zvinhu (zvakadai electroneutral kana acidic anions), Haikwanise kuchengeta chaji yakanaka.Ioni isina simba kuchinjanisa pfuma zvakare inoita kuti zvive nyore kuchengetedza iyo yakaipa yekuchaja zvinhu.

Basic aluminaIyo yepamusoro yeAlumina-B (pH = 10) inofarirwa kuchengetedza zvakanaka kana hydrogen - zvakasungwa zvinhu. Aluminium oxide yakabatwa nealkaline solution ine anionic properties uye cationic exchange function. Mukuwedzera, kunyange zvazvo nzvimbo yacho ine maitiro e-lewis base, inogona kuchengetwa nokuda kwemuenzaniso we electron, senge neutral amine compounds. Iko kugona kwakadzikira zvakanyanya kune kwaakarerekera uye acidic alumina. Uye zvakare, yakasimba hydrogen bond inogona kuwanikwa pane alumina-b, saka mhedzisiro yepolar cationic sampu iri pachena zvakare.

Neutral aluminaAlumina-N (pH = 7.5) zvakare yakasimba polar adsorbent. Pasi pemamiriro epamusoro pH, alumina yakagadzikana kupfuura iyo yeboka risina kusungwa rinoshanda. Finer particles anovimbisa zvakanaka kudhirowa kushanda, saka diki saizi cylindrical bed (50mg) ndiyo inonyanya kushandiswa chigadzirwa. Iyo adsorbent haina kurerekera kwemagetsi uye inochengetedza hupfumi hwemagetsi makomisheni akadai seanonhuhwirira uye ane mafuta amines. Panguva imwecheteyo, kune zvakare kugona kuchengetedza makomisheni ane electronegative mapoka akadai seine oxygen-ine, phosphorous uye maatomu esarufa. Alumina-N inogona kushandiswa kudhirowa uye kupatsanurwa kwezvinhu zvepolar kana zvisiri-polar mumvura-inonyungudika uye isina-aqueous samples.

Product zvakanakira:

★ Chigadzirwa chemhando yakagadzikana, yakanaka kuberekana, kutakura chiyero chekutsauka (RSD) <5%.

★ Kurongedza kwakachena uye hapana kuvharika kwemashure kukanganiswa.

★ Chiyero chekudzorera chakakwirira, uye chiyero chekudzorera chekuwedzera sampuli 10 ~ 100ppm ndiyo yakanakisisa ye95% ~ 105%.

Kuzvipira kwehutano:

★ Isu tinoona kuti chigadzirwa chese chakakodzera, tora yakasimba yemhando yekudzora mwero uye kuita ongororo yega yega.

★ Ita shuwa kuti chigadzirwa chega chega hachina kukanganiswa kusina chinhu, uye chiyero chekudzoreredza chemuenzaniso chakakwirira kune chehurumende, kusvika padanho repamusoro remhando imwechete yezvigadzirwa.

Kuzvipira kwebasa:

★ Isu tinopa rubatsiro rwehunyanzvi hwehunyanzvi hwemahara.
