Alumina (A / B / N) Alumina hwakasimba kutotanga dzokubudisa Mbiru / SPE chomupepanhau

Alumina chaiwo Lewis acid, The aruminiyamu atomu centre haina maerekitironi maviri. Rine zvakasimba polar adsorbent, akafanana silicone, Kune zvitatu yakakwirira basa kwevari acidity, alkalinity uye zvematongerwo enyika; Alumina anewo rinokosha chaizvo theπelectrons Kwezvinonhuhwirira Mahydrocarbon, Zviri nani pane silicone pamatunhu ph ezvinhu. Huru chengetedzo zvigadziriswe vari Lewis asidhi / chawo chiito, polarity naIon exchange.

Acid alumina The Lewis asidhi ehupfumi kuti alumina-A (ph = 4,5) dzakaratidzwa, mhando iyi adsorbent ane chengetedzo nani mupfumi Erekitironi yeimwe. Uyezve, kana pretreatment pamwe acidic mhinduro, asi adsorbent ane simba cationic ehupfumi, pose kazhinji varambe enyika uye okusafarira mhosva zvinhu (zvakadai electroneutral kana acidic anions), Havagoni kuchengeta zvakanaka charge.The simba Ion Exchange pfuma kunoitawo kuti zvive nyore kuramba kunaka mutariri zvinhu.

Basic alumina The pemvura Alumina-B (ph = 10) aifarirwa kuyeuka kana zvakanaka kana rehydrogen - waakaita zvinhu. Aluminum oxide kubatwa alkaline mhinduro ine anionic zvivako uye cationic Exchange chaitika. Uyezve, kunyange zvazvo pemvura ane hunhu Lewis chawo, rinogona rakaramba nokuda Erekitironi yokuenzanisira, akadai kwazvakarerekera amine yeimwe. Kugona dererei zvikuru kuti enyika uye acidic alumina. Uyezve, simba rehydrogen chisungo anogona kuwanika pamusoro alumina-b, saka kubata polar cationic mharidzo kuri pachena.

Kwazvakarerekera alumina Alumina-N (ph = 7.5) aivawo zvakasimba polar adsorbent. Under ezvinhu mukuru ph, alumina ndiyo itsige kupfuura unbonded dzichipfekeka boka. Kwazvo nezvimedu nechokwadi zvakanaka dzokubudisa kunyatsoshanda, saka duku saizi cylindrical mubhedha (50mg) ndiyo inowanzoshandiswa chigadzirwa. The adsorbent iri electrically enyika uye uderedze kuramba akapfuma yemagetsi yeimwe zvakadai anonhuhwirira uye mafuta amines. Panguva iyoyowo, kunewo kukwanisa kuyeuka yeimwe ane mapoka electronegative akadai okisijeni tubhokisi, phosphorous nesarufa maatomu. Alumina-N anogona kushandiswa dzokubudisa uye kupatsanurwa polar kana isiri polar zvinhu mumvura-soluble uye non-aqueous ivhu.

Product zvakwakanakira:

★ Product unhu akatsiga, impact zvakanaka, mutoro hama mwero kutsauka (Exchange) <5%.

★ The chiputiriso chakachena uye hapana kunyorwa nechekumashure chipingaidzo.

★ The kupora zvazvingava zvakakwirira, uye kupora mwero kuwedzera mharidzo 10 ~ 100ppm ndiyo yakanakisisa-siyana 95% ~ 105%.

Quality kuzvipira:

★ We nechokwadi kuti chigadzirwa ose ichikodzera, nemafungiro yakaoma unhu kudzora mureza uye ubudise ose batch mangé kuongorora.

★ Ivai nechokwadi kuti chigadzirwa ose asina kunyorwa chipingaidzo, uye mharidzo nokupora mwero mukuru kuti hurumende, richisvika soro zvakadini vakadarovo zvigadzirwa.

Service kuzvipira:

★ We vanopa nyanzvi hwokugadzira rutsigiro free.
