Wehewehena a me nā hiʻohiʻona

Wehewehe:

Hoʻohana ʻo WNX i ka ʻenehana hana hana automated holomua a hoʻohana i nā mea maka kiʻekiʻe e hana i nā mea kiʻekiʻeʻAmonium Cerium Sulfate.

Nā Hiʻohiʻona Koʻikoʻi:

Maʻemaʻe Kiʻekiʻe:ʻAmonium Cerium Sulfate ʻaʻohe mea haumia mai nā mea honua laha ʻole (e like me ka hao, calcium, sodium), a haʻahaʻa ka nui o ka haumia.

Ka hoʻoheheʻe maikaʻi: ʻAmonium Cerium Sulfate hiki ke hoʻoheheʻe koke i ka wai a me nā waikawa ikaika.

Kūlike:ʻO ka hoʻokele puʻupuʻu koʻikoʻi i ka hana ʻana oʻAmonium Cerium Sulfate hōʻoia i ka maikaʻi paʻa no ka hana ʻana i ka ʻoihana nui.

Mea hoʻouluulu kemika ʻoihana:ʻO ka Cerium ammonium sulfate, ma ke ʻano he oxidant ikaika, ua hoʻohana nui ʻia i ka synthesis organik e hoʻoulu i nā ʻano hana like ʻole, me ka oxidation o nā alcohols, phenols, a me nā ethers, a me ka hopena alkylation Friedel-Crafts. He mea hoʻomaka maikaʻi nō hoʻi ia no nā hopena polymerization radical manuahi, hiki ke hoʻohana ʻia e hoʻomākaukau i nā mea e like me nā hydrogels PEGMA.

Mea Hoʻohemo Phosphorus o ka Pond:Ma muli o kona mau waiwai kemika, hiki i ka ammonium cerium sulfate ke hana i kahi precipitate ma o ka hui pū ʻana o nā ion cerium a me nā ion phosphate, e wehe pono ana i nā phosphates mai nā kino wai a kōkua i ka hoʻoponopono ʻana i ka pilikia o ka eutrophication o ke kino wai. Ua hoʻopili mua nā haʻawina pili iā ia e hoʻomākaukau i nā adsorbents no ka wehe ʻana i ka fluoride nui mai ka wai inu.

Nā Pākahi a me nā Mea Ikehu:Ma ke kahua o ka ikehu hou, hiki ke hoʻohana ʻia ka ammonium cerium(IV) sulfate maʻemaʻe kiʻekiʻe e hoʻomākaukau i ka cerium oxide (CeO₂) nā nanomaterials. Hōʻike kēia mau mea i ka waiwai noi kūpono i nā cell wahie oxide paʻa (SOFC) a me ka ʻike kemika. ʻO kā lākou mau waiwai redox kū hoʻokahi (Ce⁴⁺/Ce³⁺) he kuleana ko lākou i ka hoʻololi ʻana a me ka mālama ʻana i ka ikehu.

Nā mea hana kemika waena:Ma ke ʻano he kumu cerium koʻikoʻi, ʻo ka ammonium cerium(IV) sulfate kahi mea mua no ka hana ʻana i nā hui cerium ʻē aʻe (e like me ka cerium oxide). He mea hoʻohana pinepine ʻia hoʻi ia i ka loiloi spectroscopic no ka hoʻoholo ʻana i nā mea oxidizable e like me ka nitrite, iodide, a me nā paʻakai hao haʻahaʻa (e like me ka hopena Sandell-Kolthoff).
