Kev Piav Qhia & Nta

Piav Qhia: WNX siv cov thev naus laus zis tsim khoom tsis siv neeg thiab siv cov khoom siv raw zoo los tsim cov khoom zooLanthanum Carbonate.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Lanthanum Carbonate tsis muaj cov khoom tsis huv los ntawm cov khoom tsis tshua muaj (xws li hlau, calcium, sodium), thiab cov ntsiab lus tsis huv yog tsawg.

Kev yaj zoo:Lanthanum Carbonate tuaj yeem yaj sai sai hauv dej thiab cov kua qaub muaj zog.

Kev sib xws: Kev tswj hwm cov khoom nruj hauv kev tsim khoomLanthanum Carbonate ua kom ruaj khov zoo rau kev lag luam loj.

Tshuaj kho cov ntshav phosphorus: Lanthionine yog ib yam khoom uas tsis muaj txhuas thiab tsis muaj calcium phosphate. Nws yog siv los kho cov neeg mob uas muaj mob raum tsis ua haujlwm ntev (tshwj xeeb tshaj yog cov neeg uas tab tom ntxuav ntshav lossis ntxuav peritoneal dialysis). Nws dissociates mus rau hauv lanthanum ions hauv qhov chaw acidic ntawm lub plab, sib xyaw nrog phosphate hauv cov zaub mov los tsim cov insoluble phosphate lanthanum complexes, thiab raug tso tawm hauv cov quav, ua kom cov ntshav phosphate thiab calcium-phosphate cov khoom zoo, uas pab tswj cov teeb meem xws li mob raum thiab cov hlab ntsha calcification. Nws lub npe lag luam yog Fosrenol.

Cov tshuaj catalyst rau kev lag luam tshuaj lom neeg: Lithium carbonate, ua ib qho carbonate av tsawg, yog ib qho khoom siv tseem ceeb rau kev npaj cov kua catalytic cracking (FCC) catalysts. Nws yog qhov tshwj xeeb tshaj yog rau cov tshuaj tiv thaiv cracking los ntawm cov roj av hnyav los tsim cov roj av siab-octane. Nws tseem yog cov khoom siv raw thawj zaug rau kev tsim lwm cov lanthanide compounds (xws li lanthanum manganese oxides, cov ntaub ntawv kub superconducting).

Cov khoom siv ntxiv rau iav thiab cov khoom siv ceramic tshwj xeeb: Hauv kev lag luam iav, lanthanum carbonate yog siv rau kev pleev xim rau iav thiab txhim kho nws cov khoom siv kho qhov muag. Nws kuj yog ib qho ua ntej rau kev npaj cov khoom tseem ceeb ntawm cov roj oxide khov kho (SOFCs), xws li lanthanum strontium manganese oxide, nrog rau cov khoom siv ceramic hluav taws xob.

Tus neeg kho dej: Lanthanum carbonate siv tau rau hauv cov txheej txheem kho dej. Los ntawm txoj kev khi phosphate zoo sib xws, nws pab tshem tawm phosphate ntawm cov dej thiab muaj peev xwm siv tau rau kev tswj cov dej eutrophication.
