Lanthanum chloride, e tsejoang ka tloaelo e leLaCl3, ke motsoako o nang le mefuta e fapaneng ea likopo tsa lipatlisiso tsa saense le indasteri.E 'ngoe ea mesebetsi ea eona ea bohlokoa ke lebaleng la pono ea atomic absorption spectroscopy (AAS), moo e bapalang karolo ea bohlokoa ho ntlafatsa ho nepahala le kutloisiso ea tlhahlobo.AAS ke mokhoa oa ho hlahloba o sebelisoang ho fumana hore na lintho li bokae sampuling.Ha re hlahlobeng ka botebo karolo ealanthanum chlorideho atomic absorption spectroscopy le ho utloisisa bohlokoa ba eona.
AAS e sebelisoa haholo liindastering tse ngata, ho kenyeletsoa tlhokomelo ea tikoloho, meriana, temo, metallurgy, joalo-joalo Ke mokhoa o sebelisang liathomo ho monya le ho ntša leseli ho lemoha le ho lekanya likarolo tse fapaneng sampuling e fanoeng.Sesebelisoa se sebelisoang ho AAS se na le likarolo tse 'maloa, ho kenyelletsa le lebone la cathode le se nang letho le nang le ntho ea thahasello, nebulizer, monochromator, tube ea photomultiplier,' me qetellong detector.
Lanthanum chloridee sebelisoa haholo-holo e le phetoho ea lik'hemik'hale ho atomic absorption spectrometry.Liphetoho tsa lik'hemik'hale ke lintho tse kentsoeng sampuling kapa lelakabe ho ntlafatsa botsitso ba element e ntseng e hlahlojoa le ho matlafatsa kutloisiso ea tekanyo.Ho atomic absorption spectrometry, palo e nyane ealanthanum chloridehangata e ekeletsoa mollong ka tharollo.Ka ho etsa joalo, e etsa li-complexes tse nang le likarolo tse itseng, ho li thibela ho sebelisana le lik'hemik'hale le likarolo tse ling tse teng sampuling.
O mong oa mesebetsi ea mantlha ealanthanum chlorideka atomic absorption spectrometry ke ho thibela sebopeho sa li-oxide tsa tšepe tse sa fetoheng.Ha sampole e kena mollong, e fetoha mouoane ebe e fetoha atomize.Lintho tse ling li atisa ho etsa li-oxide tse thata ho fetoha mouoane, e leng se etsang hore ho be le litekanyo tse sa nepahalang.Lanthanum chloride e sebetsa e le thibelo, e thibelang ho thehoa ha li-oxide tsena le ho netefatsa botsitso ba ntho.
Ntle le ho thibela ho thehoa ha oxides,lanthanum chloridee ka eketsa kutloisiso ea tlhahlobo.E etsa sena ka ho eketsa ts'ebetso ea ionization ea likarolo tsa analyte, e hlahisang matla a mats'oao a betere.Boikutlo bona bo ntlafetseng bo thusa ho lemoha le ho lekanya likarolo tsa trace esita le matrices a rarahaneng.Bokhoni ba ho lekanya likhahla tse tlase ke tsa bohlokoa lits'ebetsong tse fapaneng, joalo ka tlhahlobo ea tikoloho, moo boteng ba litšila tsa trace bo ka bang le tšusumetso e kholo.
Ho feta moo,lanthanum chloridee tsejoa ka ho eketsa botsitso ba likarolo tse itseng mollong.Lintho tse ling, haholo-holo tse nang le maemo a tlaase, li atisa ho ba le ho nepahala le botsitso nakong ea ts'ebetso ea atomization.Ka ho tsebisalanthanum chlorideka har'a lelakabe, botsitso ba likarolo tsena boa eketseha, bo fella ka liphello tse ka tšeptjoang le tse ka hlahisoang hape tsa tlhahlobo.
Ke habohlokoa ho hlokomela hore khetho ea ho fetola lik'hemik'hale, ho kenyelletsa lelanthanum chloride, ho itšetlehile ka ntho e itseng e hlahlojoang.Lintho tse fapaneng li ka 'na tsa e-ba le litlhoko tse fapaneng' me tsa arabela ka tsela e fapaneng boteng ba liphetoho tsa lik'hemik'hale.Ka hona, bakeng sa ho fumana liphetho tse nepahetseng tsa tlhahlobo, hoa hlokahala ho ba le kutloisiso e felletseng ea sampole e hlahlojoang le ho khetha li-modifiers tse nepahetseng tsa lik'hemik'hale.
Ha re phethela,lanthanum chloridee bapala karolo ea bohlokoa joalo ka phetoho ea lik'hemik'hale ho AAS.Mosebetsi oa eona o ka sehloohong ke ho thibela ho thehoa ha li-oxide tsa tšepe tse sa tsitsang, ho matlafatsa kutloisiso ea ho hlahloba, le ho ntlafatsa botsitso ba likarolo tse itseng.Ka ho sebelisalanthanum chlorideho AAS, bafuputsi le bahlahlobisisi ba ka fumana litekanyo tse nepahetseng le tse ka tšeptjoang, tse ba lumellang hore ba kenelle ka botebo libakeng ho tloha ho tlhokomelo ea tikoloho ho isa lipatlisisong tsa meriana.Tsoelo-pele e tsoelang pele ea theknoloji ea AAS le tšebeliso ea lisebelisoa tse sebetsang tsa lik'hemik'hale tse kanglanthanum chlorideba ntlafalitse haholo ho nepahala le kutloisiso ea tlhahlobo ea mantlha.
