Nkọwa na Atụmatụ

Nkọwa: WNX na-eji teknụzụ mmepụta akpaaka dị elu ma na-eji ihe eji emepụta ihe dị elu iji mepụta ihe dị eluLanthanum Sulfate Hydrare.

Isi Atụmatụ:

Ịdị ọcha dị elu:Lanthanum Sulfate Hydrare 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:Lanthanum Sulfate Hydrare nwere ike ịgbaze ngwa ngwa n'ime mmiri na asịd siri ike.

Nkwekọ: Njikwa ogbe siri ike na mmepụta nkeLanthanum Sulfate Hydrare

na-eme ka mma kwụsiri ike maka mmepụta nnukwu ụlọ ọrụ mmepụta ihe.

Ihe na-akpali mmepụta kemịkalụ: Lanthanum sulfate mmiri mmiri bụ akụkụ dị mkpa nke ihe na-akpali mmepụta catalytic cracking (FCC) nke a na-eji eme ihe n'ụlọ ọrụ petrochemical. Ọ nwere ike ime ka arụmọrụ nke ịtụgharị mmanụ dị arọ ka ọ bụrụ mmanụ gas na dizel dị elu. Ọ nwekwara ike ịbụ ihe na-akpali mmepụta ma ọ bụ ihe na-akpali mmepụta ihe maka mmeghachi omume ụfọdụ nke organic synthesis.

Ihe nchekwa okpomọkụ kemịkalụ: N'ihi njirimara mmeghachi omume mmiri mmiri/mmiri ya, lanthanum sulfate hydrate bụ ihe nchekwa okpomọkụ kemịkalụ na-ekwe nkwa nke ukwuu. Ọ nwere ike ịgafe mmeghachi omume a na-agbanwe agbanwe n'ime oke okpomọkụ dị ala (ihe dị ka 100°C ruo 250°C), a na-ejikwa ya maka mgbake na nchekwa nke okpomọkụ mkpofu ụlọ ọrụ mmepụta ihe. O nwere nnukwu njupụta nchekwa ike yana ogologo oge okirikiri dị mma.

Ihe Na-ewepụ Ọdọ Mmiri Phosphorus: N'ihi ihe ndị dị na kemịkalụ ya, lanthanum sulfate nwere ike iwepụ phosphate n'ime mmiri nke ọma site na mmiri ozuzo, nke na-enyere aka n'ịgwọ nsogbu nke eutrophication nke ahụ mmiri.

Ihe ndị e ji emepụta kemịkalụ: Dịka isi iyi dị mkpa nke lanthanum, lanthanum sulfate a na-amịkọrọ mmiri bụ isi ihe na-ebute ụzọ maka imepụta ihe ndị ọzọ dị na lanthanum, a na-ejikwa ya akwadebe ihe dị iche iche dị ka lanthanum oxide na phosphorus ndị dabeere na lanthanum. A na-ejikwa ya dị ka ihe na-eme ka ihe dị na ya dị na nnyocha sayensị dịka nyocha spectroscopy na mkpebi nke oke atọm nke ihe.
