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 zooAmmonium Cerium Sulfate.

Cov Nta Tseem Ceeb:

Kev Ntshiab Siab:Ammonium Cerium Sulfate 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: Ammonium Cerium Sulfate tuaj yeem yaj sai sai hauv dej thiab cov kua qaub muaj zog.

Kev sib xws:Kev tswj hwm cov khoom siv nruj heev hauv kev tsim khoomAmmonium Cerium Sulfate ua kom ruaj khov zoo rau kev lag luam loj.

Cov tshuaj lom neeg ua lag luam catalyst:Cerium ammonium sulfate, ua ib qho oxidant muaj zog, yog siv dav hauv cov organic synthesis los ua kom muaj ntau yam kev cuam tshuam, suav nrog kev oxidation ntawm cov cawv, phenols, thiab ethers, nrog rau Friedel-Crafts alkylation reaction. Nws kuj yog ib qho pib zoo rau cov tshuaj tiv thaiv dawb radical polymerization, uas tuaj yeem siv los npaj cov ntaub ntawv xws li PEGMA hydrogels.

Cov tshuaj phosphorus hauv pas dej:Vim nws cov khoom siv tshuaj lom neeg, ammonium cerium sulfate tuaj yeem tsim cov dej nag los ntawm kev sib xyaw ua ke ntawm cerium ions thiab phosphate ions, tshem tawm cov phosphates ntawm cov dej thiab pab daws qhov teeb meem ntawm cov dej eutrophication. Cov kev tshawb fawb cuam tshuam twb tau siv nws los npaj cov adsorbents rau kev tshem tawm cov fluoride ntau dhau ntawm cov dej haus.

Cov Roj Teeb thiab Cov Khoom Siv Hluav Taws Xob:Hauv thaj teb ntawm lub zog tshiab, cov khoom siv ammonium cerium (IV) sulfate uas muaj cov khoom ntshiab siab siv tau los npaj cerium oxide (CeO₂) cov ntaub ntawv nano. Cov ntaub ntawv no qhia txog qhov muaj peev xwm siv tau rau hauv cov roj oxide khov kho (SOFC) thiab kev tshuaj lom neeg. Lawv cov khoom tshwj xeeb redox (Ce⁴⁺/Ce³⁺) ua lub luag haujlwm hauv kev hloov pauv hluav taws xob thiab khaws cia.

Cov tshuaj lom neeg nruab nrab:Ua ib qho tseem ceeb ntawm cerium, ammonium cerium (IV) sulfate yog ib qho tseem ceeb ua ntej rau kev tsim lwm cov cerium compounds (xws li cerium oxide). Nws kuj yog ib qho tshuaj siv feem ntau hauv kev tshuaj ntsuam spectroscopic rau kev txiav txim siab cov tshuaj oxidizable xws li nitrite, iodide, thiab cov ntsev hlau qis (piv txwv li, Sandell-Kolthoff reaction).
