Inkcazo kunye neempawu

Inkcazo:

I-WNX isebenzisa ubuchwepheshe bokuvelisa obuzenzekelayo obuphambili kwaye isebenzisa izinto ezisemgangathweni ophezulu ukuvelisa umgangatho ophezuluI-Ammonium Cerium Sulfate.

Ezona mpawu:

Ubunyulu obuphezulu:I-Ammonium Cerium Sulfate ayinazo izinto ezingcolisayo ezivela kwizinto ezinqabileyo zomhlaba (ezifana nesinyithi, ikhalsiyam, isodiyam), kwaye umxholo wokungcola uphantsi.

Ukunyibilika Okulungileyo: I-Ammonium Cerium Sulfate inokunyibilika ngokukhawuleza emanzini nakwii-asidi ezinamandla.

Ukungaguquguquki:Ulawulo olungqongqo lwebhetshi ekuvelisweni kweI-Ammonium Cerium Sulfate iqinisekisa umgangatho ozinzileyo kwimveliso emikhulu yemizi-mveliso.

Isincedisi semizi-mveliso sekhemikhali:I-Cerium ammonium sulfate, njenge-oxidant enamandla, isetyenziswa kakhulu kwi-organic synthesis ukuququzelela ii-reactions ezahlukeneyo, kubandakanya i-oxidation ye-alcohols, i-phenols, kunye ne-ethers, kunye ne-Friedel-Crafts alkylation reaction. Ikwangumqalisi osebenzayo we-free radical polymerization reactions, enokusetyenziselwa ukulungiselela izinto ezifana ne-PEGMA hydrogels.

Isisusi sePhosphorus sedama:Ngokusekelwe kwiimpawu zayo zeekhemikhali, i-ammonium cerium sulfate inokwenza i-precipitate ngokudityaniswa kwee-ion ze-cerium kunye nee-ion ze-phosphate, isuse ii-phosphates kwimizimba yamanzi kwaye incede ekusombululeni ingxaki ye-eutrophication yomzimba wamanzi. Izifundo ezifanelekileyo sele ziyisebenzise ukulungiselela ii-adsorbents zokususa i-fluoride egqithisileyo emanzini okusela.

Iibhetri kunye nezixhobo zamandla:Kwintsimi yamandla amatsha, i-ammonium cerium(IV) sulfate enobunyulu obuphezulu ingasetyenziselwa ukulungiselela i-cerium oxide (CeO2).₂) izinto ze-nanomaterials. Ezi zinto zibonisa ixabiso elinokubakho lokusetyenziswa kwiiseli zamafutha ze-oxide eziqinileyo (SOFC) kunye nokuva iikhemikhali. Iimpawu zazo ezikhethekileyo ze-redox (Ce⁴⁺/Ce³⁺) zidlala indima ekuguqulweni nasekugcinweni kwamandla.

Izinto ezidityanisiweyo zekhemikhali:Njengomthombo obalulekileyo we-cerium, i-ammonium cerium(IV) sulfate sisiseko esiphambili sokudibanisa ezinye iikhompawundi ze-cerium (ezifana ne-cerium oxide). Ikwayindlela esetyenziswa kakhulu yokuhlaziya kuhlalutyo lwe-spectroscopic ukumisela izinto ezinokuxovwa ezifana ne-nitrite, iodide, kunye ne-low-valent iron salts (umz., i-Sandell-Kolthoff reaction).
