Inkcazo kunye neempawu

Inkcazo: I-WNX isebenzisa ubuchwepheshe bokuvelisa obuzenzekelayo obuphambili kwaye isebenzisa izinto ezisemgangathweni ophezulu ukuvelisa umgangatho ophezuluI-Lanthanum Nitrate.

Ezona mpawu:

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

Ukunyibilika Okulungileyo:I-Lanthanum Nitrate inokunyibilika ngokukhawuleza emanzini nakwii-asidi ezinamandla.

Ukungaguquguquki: Ulawulo olungqongqo lwebhetshi ekuvelisweni kweI-Lanthanum Nitrate iqinisekisa umgangatho ozinzileyo kwimveliso emikhulu yemizi-mveliso.

I-catalyst yezekhemikhali kwimizi-mveliso: I-Lanthanum nitrate isebenza njenge-catalyst esebenzayo ye-Lewis acid kwaye isetyenziswa kakhulu kwiimpendulo ezahlukeneyo zokuguqulwa kwezinto eziphilayo, ezifana neempendulo ze-acetylation ze-alcohols, ii-phenols, kunye nee-amines, kunye nokuhlanganiswa kwe-acetaldehydes kunye ne-bis(indolyl) methane ngokudibanisa i-aldehydes kunye ne-alcohols. Ikwayinxalenye ebalulekileyo ekulungiseleleni ii-catalysts ze-petroleum catalytic cracking (FCC), ezinceda ukuphucula ukusebenza kakuhle kunye nomgangatho wokuveliswa kwepetroli.

I-Arhente yokususa i-Phosphorus esebenzayo: Ngenxa yeempawu zayo zeekhemikhali, i-lanthanum nitrate inokususa i-phosphate ngokufanelekileyo kwimizimba yamanzi ngemvula, nto leyo enceda ekusombululeni ingxaki ye-eutrophication yomzimba wamanzi. Le propati ikwavumela ukusetyenziswa kwayo njengearhente yonyango lwedama lokudada ukususa i-phosphate efunekayo ekukhuleni kwe-algae.

Isayensi yezoLimo neZityalo: Uphando lubonise ukuba ukuxinana okuphakathi kwe-lanthanum nitrate kunokulawula umxholo we-vitamin C (Vc) kwiziqhamo zezityalo ezifana neestrawberry. Oku kufezekiswa ngokuchaphazela imisebenzi yee-enzymes eziphambili (ezifana neGalLDH) kwindlela yokwenza izinto eziphilayo, ukuhlaziywa, kunye neendlela zokuwohloka. Kunganciphisa nefuthe lokuthintela uxinzelelo lwe-alkaline kunye nezinye uxinzelelo lokusingqongileyo ekukhuleni kwe-ryegrass, kwaye kukhuthaze ukukhula kwezityalo ngokuphucula umxholo wee-pigment ze-photosynthetic kunye nokusebenza kakuhle kokudluliselwa kwe-electron ye-photosynthetic.

Izinto ezisetyenziswayo kunye nezinto ezisetyenziswa ngamakhemikhali: I-Lanthanum nitrate sisiseko esibalulekileyo sokulungiselela izinto ezahlukeneyo ezisebenzayo eziphambili. Isetyenziswa ekuhlanganiseni iglasi ye-optical, iipowders ze-fluorescent, izongezo ze-ceramic capacitor (ezifana ne-strontium titanate lanthanum), kunye nokulungiselela i-lanthanum manganese oxide (LaMnO2).₃) iifilimu ngokusebenzisa indlela ye-sol-gel okanye i-electrochemical deposition. Ukongeza, ikwayinto ebalulekileyo esetyenziswa phakathi kwemveliso yezinye iikhompawundi ze-lanthanum (ezifana ne-lanthanum oxide).
