Kufotokozera & Makhalidwe

Kufotokozera:

WNX imagwiritsa ntchito ukadaulo wapamwamba wopanga zinthu ndipo imagwiritsa ntchito zipangizo zapamwamba kwambiri kuti ipange zinthu zapamwamba kwambiri.Ammonium Cerium Sulfate.

Zinthu Zofunika Kwambiri:

Kuyera Kwambiri:Ammonium Cerium Sulfate Mulibe zodetsa zochokera ku zinthu zosoŵa zapadziko lapansi (monga chitsulo, calcium, sodium), ndipo kuchuluka kwa zodetsazo n'kochepa.

Kusungunuka Kwabwino: Ammonium Cerium Sulfate imatha kusungunuka mofulumira m'madzi ndi m'ma asidi amphamvu.

Kusasinthasintha:Kuyang'anira bwino kwambiri kupanga zinthuAmmonium Cerium Sulfate kuonetsetsa kuti zinthu zopangidwa m'mafakitale akuluakulu zikhale zabwino komanso zokhazikika.

Chothandizira cha mafakitale cha mankhwala:Cerium ammonium sulfate, monga oxidant yamphamvu, imagwiritsidwa ntchito kwambiri popanga zinthu zachilengedwe kuti ipangitse zinthu zosiyanasiyana, kuphatikizapo kusungunuka kwa ma alcohols, ma phenols, ndi ma ether, komanso Friedel-Crafts alkylation reaction. Ndiwoyambitsanso bwino ma free radical polymerization reactions, omwe angagwiritsidwe ntchito pokonzekera zinthu monga ma PEGMA hydrogels.

Chochotsera Phosphorus pa Dziwe:Kutengera ndi mankhwala ake, ammonium cerium sulfate imatha kupanga precipitate kudzera mu kuphatikiza kwa ma ion a cerium ndi ma ion a phosphate, kuchotsa bwino ma phosphate m'madzi ndikuthandizira kuthetsa vuto la eutrophication m'madzi. Kafukufuku wofunikira wagwiritsa ntchito kale kukonzekera zosakaniza zochotsera fluoride wambiri m'madzi akumwa.

Mabatire ndi Zipangizo Zamphamvu:Pankhani ya mphamvu zatsopano, ammonium cerium (IV) sulfate yoyera kwambiri ingagwiritsidwe ntchito kukonzekera cerium oxide (CeO2).₂) zinthu zopangidwa ndi nanomaterials. Zinthuzi zimasonyeza kufunika kogwiritsidwa ntchito mu ma cell amafuta olimba okosijeni (SOFC) ndi chemical sensing. Kapangidwe kake kapadera ka redox (Ce)⁴⁺/Ce³⁺) zimathandiza pakusintha ndi kusunga mphamvu.

Mankhwala opangidwa ndi mankhwala:Monga gwero lofunika la cerium, ammonium cerium(IV) sulfate ndi chinthu chofunikira kwambiri popanga mankhwala ena a cerium (monga cerium oxide). Ndi chinthu chomwe chimagwiritsidwanso ntchito kwambiri pofufuza zinthu zomwe zimatha kusungunuka monga nitrite, iodide, ndi mchere wachitsulo wotsika (monga Sandell-Kolthoff reaction).
