I-Lanthanum chloride, eyaziwa njengeLaCl3, yikhompawundi eneentlobo ngeentlobo zezicelo kuphando lwezenzululwazi nakushishino.Omnye wemisebenzi yayo ebalulekileyo kwintsimi ye-atomic absorption spectroscopy (AAS), apho idlala indima ebalulekileyo ekuphuculeni ukuchaneka kunye novakalelo lokuhlalutya.I-AAS bubuchule bokuhlalutya obusetyenziselwa ukumisela ukuxinwa kwezinto kwisampulu.Makhe sijonge ngakumbi indima kai-lanthanum chloridekwi-athom yokufunxa i-spectroscopy kunye nokuqonda ukubaluleka kwayo.
I-AAS isetyenziswa ngokubanzi kumashishini amaninzi, kubandakanywa ukubeka iliso kokusingqongileyo, amayeza, ezolimo, i-metallurgy, njl. Bubuchule obusebenzisa ii-athomu ukufunxa nokukhupha ukukhanya ukufumanisa nokulinganisa izinto ezahlukeneyo kwisampulu enikiweyo.I-instrumentation esetyenziswe kwi-AAS iqulethwe ngamacandelo amaninzi, kubandakanywa isibane se-cathode esingenanto kunye nento enomdla, i-nebulizer, i-monochromator, i-tube ye-photomultiplier, kwaye ekugqibeleni i-detector.
I-Lanthanum chlorideisetyenziswa ngokuyintloko njengesilungisi seekhemikhali kwi-atomic absorption spectrometry.Izilungisi zemichiza zizinto ezongeziweyo kwisampulu okanye kwidangatye ukuphucula uzinzo lwento ehlalutywayo kunye nokuphucula ubuntununtunu bomlinganiselo.Kwi-atomic absorption spectrometry, inani elincinci lei-lanthanum chlorideidla ngokufakwa kwidangatye kwisisombululo.Ngokwenza njalo, yenza ii-complexes kunye nezinto ezithile, zithintele ukuba zidibanise iikhemikhali kunye namanye amacandelo akhoyo kwisampuli.
Omnye wemisebenzi ephambili yei-lanthanum chloridekwi-athom yokufunxa i-spectrometry kukuthintela ukwakheka kweeoksidi zetsimbi ezingaguqukiyo.Xa isampulu ingena edangatyeni, iyaphuphuma kwaye iatomize.Ezinye iielementi zikholisa ukwenza iioksidi ekunzima ukuzikhupha zibe ngumphunga, nto leyo ekhokelela kwimilinganiselo engachanekanga.I-Lanthanum chloride isebenza njengomqobo, ukukhusela ukubunjwa kwezi oxides kunye nokuqinisekisa ukuzinza kwento.
Ukongeza ekuthinteleni ukwakheka kweeoksidi,i-lanthanum chlorideinokunyusa uvakalelo lohlalutyo.Ikwenza oku ngokwandisa ukusebenza kakuhle kwe-ionization yezinto zokuhlalutya, okukhokelela kumandla omqondiso angcono.Olu buntununtunu luphuculweyo lwenza ukuba kufunyanwe kunye nobungakanani bezinto zomkhondo nakwimatriki ezintsonkothileyo.Ukukwazi ukulinganisa ukugxininiswa okuphantsi kubaluleke kakhulu kwiintlobo ezahlukeneyo zezicelo, ezifana nokuhlalutya okusingqongileyo, apho ubukho bomkhondo ongcolileyo bunokuba nefuthe elikhulu.
Ukongeza,i-lanthanum chlorideyaziwa ngokunyusa uzinzo kwizinto ezithile kwidangatye.Ezinye izinto, ngakumbi ezo zine-volatility ephantsi, zikholisa ukungachaneki kakuhle kunye nokuzinza ngexesha lenkqubo ye-atomization.Ngokuzisai-lanthanum chloridekwidangatye, ukuzinza kwezi zinto kwanda, okukhokelela kwiziphumo ezithembekileyo nezinokuphinda ziphinde zihlalutye.
Kubalulekile ukuba uqaphele ukuba ukhetho lwe-chemical modifier, kubandakanywai-lanthanum chloride, kuxhomekeke kwinto ethile ehlalutywayo.Izinto ezahlukeneyo zinokuba neemfuno ezahlukeneyo kwaye ziphendule ngokuhlukileyo kubukho bemichiza yeekhemikhali.Ngoko ke, ukuze ufumane iziphumo ezichanekileyo zokuhlalutya, kuyimfuneko ukuqonda ngokubanzi isampuli ehlalutywayo kunye nokukhetha izilungiso zeekhemikhali ezifanelekileyo.
Ukuququmbela,i-lanthanum chlorideidlala indima ebalulekileyo njengesimo samachiza kwi-AAS.Umsebenzi wayo oyintloko kukuthintela ukubunjwa kwee-oxide zetsimbi ezingaguqukiyo, ukwandisa uvakalelo lokuhlalutya, kunye nokuphucula ukuzinza kwezinto ezithile.Ngokusebenzisai-lanthanum chloridekwi-AAS, abaphandi kunye nabahlalutyi banokufumana imilinganiselo echanekileyo kunye nethembekileyo, ebavumela ukuba bangene nzulu kwimimandla ukusuka ekubekweni kweliso kwendalo ukuya kuphando lwamachiza.Ukuqhubela phambili okuqhubekayo kwethekhnoloji ye-AAS kunye nokusetyenziswa kwezilungiso zeekhemikhali ezisebenzayo ezifanai-lanthanum chloridebaphucule kakhulu ukuchaneka kunye novakalelo lohlalutyo olusisiseko.
