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 kiʻekiʻeʻO ka sulfate Ceric.

Nā Hiʻohiʻona Koʻikoʻi:

Maʻemaʻe Kiʻekiʻe:ʻO ka sulfate Ceric 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:ʻO ka sulfate Ceric hiki ke hoʻoheheʻe koke i ka wai a me nā waikawa ikaika.

Kūlike: ʻO ka hoʻokele puʻupuʻu koʻikoʻi i ka hana ʻana oʻO ka sulfate Ceric hōʻoia i ka maikaʻi paʻa no ka hana ʻana i ka ʻoihana nui.

Mea hoʻouluulu kemika ʻoihana: ʻO ka sulfuric acid kiʻekiʻe cerium, ma ke ʻano he oxidant ikaika, hoʻohana ʻia i ka synthesis organik e hoʻouluulu i nā ʻano hana like ʻole, me ka oxidation koho o nā alcohols i ketones, ka sulfonation pololei o ka methane a me ka trioxide sulfur e hana i ka methanesulfonic acid, a me ka catalysis o ka condensation o 2-naphthol me aldehydes ma lalo o nā kūlana solvent-free a me microwave e synthesize i ka 14-aryl a i ʻole 14-alkyl-14H-dibenz[a,j]sulfuranthene. He mea koʻikoʻi loa kona waiwai oxidizing ma lalo o nā kūlana acidic.

Mea Hoʻohemo Phosphorus Loko: Ma muli o kona mau waiwai kemika, hiki i ka cerium kiʻekiʻe o ka waikawa sulfuric ke hoʻoneʻe pono i ka phosphate mai nā kino wai ma o ka ua, he mea kōkua ia i ka hoʻoponopono ʻana i ka pilikia o ka eutrophication o ke kino wai.

Nā pila a me nā mea ikehu: Hoʻohana ʻia ka waikawa sulfuric me ka nui o ka cerium ma ke ʻano he precursor no ka hoʻomākaukau ʻana i ka cerium oxide (CeO₂) nā nanospheres. Hōʻike kēia mau nanomaterials i ka hana catalytic maikaʻi loa i ka hopena hōʻemi o ka nitric oxide (NO) a loaʻa iā lākou nā noi kūpono i nā kahua o ka ikehu a me ka catalysis kaiapuni.

ʻO ka waena hana kemika: ʻO ka sulfuric acid cerium(IV) kahi mea hana loiloi koʻikoʻi, i hoʻohana nui ʻia i nā titrations oxidation-reduction (e like me ke calibrating sodium thiosulfate solutions) e hoʻoholo i nā mea hiki ke oxidized, e like me ka nitrite, iodide, a me nā paʻakai hao haʻahaʻa. He waena koʻikoʻi nō hoʻi ia no ka hana ʻana i nā hui cerium ʻē aʻe (e like me ka cerium dioxide).
