Whakaahuatanga me ngā Āhuatanga

Whakaahuatanga:

Ka whakamahia e WNX te hangarau whakaputa aunoa matatau, ā, ka whakamahia ngā rauemi mata kounga teitei hei whakaputa i te kounga teitei.Āmoniuma Cerium Sulfate.

Ngā Āhuatanga Matua:

Teitei o te Parakore:Āmoniuma Cerium Sulfate kāore he poke o ngā huānga whenua onge (pērā i te rino, te konupūmā, te konutai), ā, he iti noa te nui o te poke.

Te Wairewatanga Pai: Āmoniuma Cerium Sulfate ka tere te memeha i roto i te wai me ngā waikawa kaha.

Te ōritetanga:Te whakahaere pakari o ngā puranga i roto i te whakaputanga oĀmoniuma Cerium Sulfate e whakarite ana i te kounga pumau mō te whakaputanga ahumahi nui.

Whakakōkī matū ahumahi:Ko te cerium ammonium sulfate, hei matū whakahāora kaha, e whakamahia whānuitia ana i roto i te hanga rauropi hei whakatere i ngā tauhohenga maha, tae atu ki te whakahāora o ngā waipiro, ngā phenol, me ngā ether, tae atu ki te tauhohenga alkylation Friedel-Crafts. He mea whakaoho whai hua hoki mō ngā tauhohenga polymerization radical kore utu, ka taea te whakamahi hei whakarite rauemi pēnei i ngā hydrogel PEGMA.

Tango Phosphorus Puna:I runga i ōna āhuatanga matū, ka taea e te ammonium cerium sulfate te hanga i tētahi matūriki mā te whakakotahitanga o ngā katote cerium me ngā katote phosphate, ka tango pai i ngā phosphate mai i ngā wai, ā, ka āwhina hoki ki te whakatika i te raruraru o te eutrophication o ngā wai. Kua whakamahia kētia e ngā rangahau e tika ana hei whakarite i ngā adsorbents hei tango i te nui o te fluoride mai i te wai inu.

Ngā Pūhiko me ngā Rauemi Pūngao:I roto i te mara o te pūngao hou, ka taea te whakamahi i te ammonium cerium(IV) sulfate parakore-teitei hei hanga i te cerium oxide (CeO₂) ngā rauemi nano. E whakaatu ana ēnei rauemi i te uara tono pea i roto i ngā pūtau wahie waikura totoka (SOFC) me te pūoko matū. Ō rātou āhuatanga redox ahurei (Ce⁴⁺/Ce³⁺) he mahi tā rātou ki te huri me te rokiroki pūngao.

Ngā takawaenga matū hangai:Hei pūtake nui o te cerium, ko te ammonium cerium(IV) sulfate he matū matua mō te hanga i ētahi atu pūhui cerium (pērā i te cerium oxide). He matū tātari hoki e whakamahia whānuitia ana i roto i te tātaritanga matawhenua hei whakatau i ngā matū ka taea te whakapūngao pērā i te nitrite, te iodide, me ngā tote rino iti-valent (hei tauira, te tauhohenga Sandell-Kolthoff).
