Alumina (ABN) SPE
Alumina(A/B/N)Alumina olimba gawo la m'zigawo / gawo la SPE
Alumina ndi wamba lewis asidi, Aluminiyamu atomu pakati alibe ma elekitironi awiri.Ili ndi polar adsorbent, yofanana ndi ya silikoni, Pali magawo atatu apamwamba a acidity, alkalinity ndi kusalowerera ndale;Alumina imakhalanso ndi mphamvu yapadera pa ma electron a ma hydrocarbon onunkhira, Ndi bwino kuposa silikoni yomwe ili ndi pH yapamwamba.Njira zazikulu zosungira ndi lewis acid/base action, polarity ndi ion exchange.
Asidi aluminiyamuMa lewis acid a alumina-A (pH = 4.5) adalimbikitsidwa, Mtundu uwu wa adsorbent umasungidwa bwino pamagulu olemera a elekitironi.Kuonjezera apo, pamene pretreatment ndi njira acidic, ndi adsorbent ali ofooka cationic katundu, pamwamba akhoza kusunga ndale ndi zoipa mlandu zinthu (monga electroneutral kapena acidic anions), Sangathe kusunga zabwino charge.The ofooka ion kuwombola katundu. Zimapangitsanso kuti zikhale zosavuta kusunga zinthu zoipa.
Basic aluminaPamwamba pa Alumina-B (pH = 10) amakonda kusunga zinthu zabwino kapena zomangika za haidrojeni.Aluminiyamu okusayidi wothiridwa ndi alkaline yankho ali ndi anionic katundu ndi cationic kusinthana ntchito.Kuonjezera apo, ngakhale kuti pamwamba ili ndi makhalidwe a lewis base, akhoza kusungidwa kwa chitsanzo cha electron, monga mankhwala osalowerera amine.Kutha kwake ndikotsika kwambiri kwa aluminiyamu wosalowerera komanso acidic.Kuphatikiza apo, chomangira champhamvu cha haidrojeni chimapezeka pa alumina-b, kotero zotsatira za chitsanzo cha polar cationic ndizodziwikiratu.
Aluminiyamu wosalowereraAlumina-N (pH = 7.5) ndi adsorbent kwambiri polar.Pansi pa pH yapamwamba, alumina imakhala yokhazikika kuposa ya gulu losamangidwa.Tinthu tating'onoting'ono timaonetsetsa kuti m'zigawo zikuyenda bwino, kotero bedi laling'ono la cylindrical (50mg) ndilogwiritsidwa ntchito kwambiri.Ma adsorbent ndi osalowerera pamagetsi ndipo amakonda kusunga zinthu zamagetsi zamagetsi monga zonunkhira ndi mafuta amines.Panthawi imodzimodziyo, palinso mphamvu yosunga mankhwala omwe ali ndi magulu a electronegative monga maatomu okhala ndi mpweya, phosphorous ndi sulfure.Alumina-N angagwiritsidwe ntchito m'zigawo ndi kulekanitsa zinthu polar kapena sanali polar mu madzi sungunuka ndi sanali amadzimadzi zitsanzo.
Ubwino wazinthu:
★ Ubwino wazinthu ndi wokhazikika, kuberekana kwabwino, kulemetsa kwapang'onopang'ono (RSD) <5%.
★ Zonyamula ndi zoyera ndipo palibe chosokoneza chakumbuyo.
★ Mlingo wochira ndiwokwera, ndipo kuchuluka kwa kuchira kowonjezera chitsanzo 10 ~ 100ppm ndikosiyana kwambiri ndi 95% ~ 105%.
★ Kukwera mtengo kwazinthu ndi chimodzi mwazinthu zabwino kwambiri padziko lonse lapansi.
Kuchuluka kwa ntchito:
★ Dothi;Mafuta;Zamadzimadzi amthupi (plasma/mkodzo etc.);Chakudya;mankhwala etc.
Ntchito yodziwika bwino:
★ Mafuta, zopangira mafuta aiwisi, zopangira organic.(N）
★ Sudan wofiira, malachite wobiriwira, mavitamini, mankhwala, mafuta onunkhira, michere, glycosides ndi mahomoni, etc.(N）
★ Kupatukana kwa zinthu zotulutsa ma radioactive, ma jenereta a isotopu.(A,B）
★ The phospholipids, steroids, catecholamine.(B）
★ Zakudya/zakudya zowonjezera.(A,N）
★ Mankhwala, herbicides, kulekanitsa zowononga.(N,B）
★ Non-polar organic adsorbents, mafuta ndi lipid kulekana
★ Zopangira organic zimasiyanitsidwa.
★ Zogulitsa zachilengedwe, mitundu ya zomera.
★ Japan JPMHLW njira yovomerezeka: mankhwala ophera tizilombo muzakudya.
★ Njira za AOAC ndi EPA.
Kudzipereka kwabwino:
★ Timaonetsetsa kuti mankhwala aliwonse ndi oyenerera, timatengera kuwongolera kokhazikika komanso kuwunika kulikonse.
★ Onetsetsani kuti chinthu chilichonse chilibe chosokoneza chilichonse, ndipo chiwerengero cha kuchira kwachitsanzo ndichoposa cha boma, kufika pamtunda wapamwamba kwambiri wamtundu womwewo.
Kudzipereka kwautumiki:
★ Timapereka chithandizo chaukadaulo kwaulere.
