Isi Atụmatụ:

Ịdị ọcha dị elu:Ammonium Cerium sulfate enweghị ihe ruru unyi sitere na ihe ndị dị n'ụwa dị ụkọ (dịka iron, calcium, sodium), ihe ruru unyi dị n'ime ya dịkwa obere.

Ezi mgbaze: Ammonium Cerium sulfate nwere ike ịgbaze ngwa ngwa n'ime mmiri na asịd siri ike.

Ndakọrịta:Njikwa ogbe siri ike na mmepụta nkeAmmonium Cerium sulfate na-eme ka mma kwụsiri ike maka mmepụta nnukwu ụlọ ọrụ mmepụta ihe.

Ihe mkpali ụlọ ọrụ kemịkalụ:A na-ejikarị Cerium ammonium sulfate, dị ka ihe na-eme ka ihe dị ike rụọ ọrụ, eme ihe n'ọtụtụ ebe na njikọ organic iji mee ka mmeghachi omume dị iche iche ka mma, gụnyere oxidation nke alcohols, phenols, na ethers, yana mmeghachi omume alkylation Friedel-Crafts. Ọ bụkwa ihe mmalite dị irè maka mmeghachi omume polymerization radical n'efu, nke enwere ike iji kwadebe ihe dịka PEGMA hydrogels.

Ihe na-ewepụ Ọdọ Mmiri Phosphorus:Dabere na ihe ndị dị na kemịkalụ ya, ammonium cerium sulfate nwere ike ịmepụta ihe na-akpali akpali site na njikọta nke ion cerium na ion phosphate, na-ewepụ phosphates n'ime mmiri nke ọma ma na-enyere aka idozi nsogbu nke eutrophication nke ahụ mmiri. Ọmụmụ ihe ndị dị mkpa etinyelarị ya iji kwadebe ihe ndị na-adọrọ adọrọ maka iwepụ fluoride gabigara ókè na mmiri ọṅụṅụ.

Batrị na ihe eji arụ ọrụ ike:N'ọhịa ike ọhụrụ, enwere ike iji ammonium cerium (IV) sulfate dị ọcha nke ukwuu iji kwadebe cerium oxide (CeO2)₂) ihe ndị dị na nanomaterials. Ihe ndị a na-egosi uru ojiji nwere ike ịba na mkpụrụ ndụ mmanụ ọkụ siri ike (SOFC) na mmetụta kemịkalụ. Njirimara redox pụrụ iche ha (Ce⁴⁺/Ce³⁺) na-arụ ọrụ na mgbanwe ike na nchekwa.

Ihe ndị mejupụtara kemịkalụ sịntetik:Dịka isi iyi cerium dị mkpa, ammonium cerium (IV) sulfate bụ isi ihe na-ebute ụzọ maka imepụta ihe ndị ọzọ dị na cerium (dịka cerium oxide). Ọ bụkwa ihe a na-ejikarị eme ihe na nyocha spectroscopic maka ịchọpụta ihe ndị nwere ike ime ka oxidize dị ka nitrite, iodide, na nnu ígwè dị ala (dịka ọmụmaatụ, mmeghachi omume Sandell-Kolthoff).
