Bismuth oxide suav tias yog ib yooj yim oxide , uas piav qhia txog qhov kev ua haujlwm siab nrog CO2. Txawm li cas los xij, thaum acidic cations xws li Si(IV) yog qhia nyob rau hauv cov qauv ntawm cov bismuth oxide , cov tshuaj tiv thaiv nrog CO2 tsis tshwm sim.

Hauv qhov no, bismuth oxide siv rau dab tsi?

Daim ntawv thov. Cov kev siv tseem ceeb ntawm bismuth oxide nanoparticles yog cov ntaub ntawv siv hluav taws xob, xws li hauv electrolyte lossis cathode ntawm cov khoom oxide roj hlwb (SOFC), nyob rau hauv bio-kev kho mob thiab mob qog noj ntshav thiab rau lwm yam photoconductive yam ntxwv nyob rau hauv nyias films.

Ib yam li ntawd, vim li cas bismuth tsis yog acidic? Bismuth oxide tsis yog acidic nyob rau hauv ib qho ntawm nws cov tshuaj tiv thaiv. Lub caij muaj tus nqi siab dua ntawm electronegativity yuav yog qhov tseem ceeb a tsis yog -hlau thaum uas tus nqi qis dua yuav yog hlau. Electronegativity txo qis ntawm kev txav ntawm sab saum toj mus rau hauv qab. thiab cov oxide ntawm Bi yog qhov yooj yim.

Tsis tas li ntawd, bismuth puas lom rau tib neeg?

Bismuth Toxicity yog suav tias yog ib qho tsawg kawg nkaus tshuaj lom cov hlau hnyav. Bismuth toxicity feem ntau yog txuam nrog raug rau bismuth ntsev (muag raws li lub npe Pepto-Bismol). Ua hauj lwm bismuth raug tsis tshua muaj. Bismuth tuaj yeem nqus tau, noj, lossis nqus los ntawm daim tawv nqaij.

Yuav ua li cas ua bismuth oxide?

Yog koj xav tau ua koj oxide , tsuas yaj lub bismuth nyob rau hauv nitric acid thiab thaum tag nrho cov hlau tau ploj lawm, ces boil rau cov kua. Ntawm ib qho taw tes koj tau ib daim ntawv ntub dej. Ua kom cua sov, tshem tawm cov dej vapor thiab vapor ntawm nitric acid. Ua kom cua sov ntxiv thiab muaj zog dua, koj tau nitric oxide (xim xim av).
