Lanthanum kloride, omwe amadziwika kutiLaCl3, ndi gulu lomwe lili ndi ntchito zosiyanasiyana pa kafukufuku wa sayansi ndi mafakitale.Imodzi mwa ntchito zake zofunika ndi gawo la ma atomic mayamwidwe spectroscopy (AAS), komwe imagwira ntchito yofunika kwambiri pakuwongolera kulondola komanso chidwi cha kusanthula.AAS ndi njira yowunikira yomwe imagwiritsidwa ntchito kudziwa kuchuluka kwa zinthu mu zitsanzo.Tiyeni tione mwatsatanetsatane udindo walanthanum kloridemu atomiki mayamwidwe spectroscopy ndi kumvetsa kufunika kwake.
AAS imagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kuphatikizapo kuyang'anira zachilengedwe, mankhwala, ulimi, zitsulo, ndi zina zotero. Ndi njira yomwe amagwiritsa ntchito maatomu kuti atenge ndi kutulutsa kuwala kuti azindikire ndi kuwerengera zinthu zosiyanasiyana mu chitsanzo choperekedwa.Chida chomwe chimagwiritsidwa ntchito mu AAS chimakhala ndi zigawo zingapo, kuphatikizapo nyali ya cathode yopanda kanthu yokhala ndi chinthu chosangalatsa, nebulizer, monochromator, chubu cha photomultiplier, ndipo potsiriza chowunikira.
Lanthanum klorideamagwiritsidwa ntchito makamaka ngati mankhwala osintha mu atomic absorption spectrometry.Zosintha za Chemical ndi zinthu zomwe zimawonjezeredwa ku zitsanzo kapena lawi kuti zithandizire kukhazikika kwa chinthu chomwe chikuwunikidwa ndikuwonjezera chidwi cha muyeso.Mu atomiki mayamwidwe spectrometry, pang'onolanthanum kloridenthawi zambiri amawonjezedwa kumoto mu njira yothetsera.Pochita izi, zimapanga ma complexes ndi zinthu zina, kuwalepheretsa kuti asagwirizane ndi mankhwala ndi zigawo zina zomwe zilipo mu chitsanzo.
Imodzi mwa ntchito zoyambirira zalanthanum kloridemu atomiki mayamwidwe spectrometry ndi ziletsa mapangidwe sanali kosakhazikika zitsulo oxides.Chitsanzocho chikalowa mumoto, chimasanduka nthunzi ndikusanduka atomize.Zinthu zina zimakonda kupanga ma oxides omwe amavuta kusuntha, zomwe zimapangitsa kuti miyeso yolakwika ikhale yolakwika.Lanthanum kolorayidi amachita ngati chotchinga, kuteteza mapangidwe oxides izi ndi kuonetsetsa bata la chinthu.
Kuphatikiza pa kuletsa mapangidwe a oxides,lanthanum klorideakhoza kuwonjezera chidwi cha kusanthula.Imachita izi powonjezera mphamvu ya ionization ya zinthu za analyte, zomwe zimapangitsa mphamvu yama siginecha.Kukhudzika kosinthika kumeneku kumathandizira kuzindikira ndikuchulukira kwa zinthu zotsatsira ngakhale mu matrices ovuta.Kukhoza kuyeza zochepetsetsa ndizofunika kwambiri pazochitika zosiyanasiyana, monga kusanthula chilengedwe, kumene kukhalapo kwa zowonongeka kungayambitse kwambiri.
Kuonjezera apo,lanthanum klorideamadziwika kuti amawonjezera kukhazikika kwa zinthu zina mumoto.Zinthu zina, makamaka zomwe zimakhala ndi kusinthasintha kochepa, zimakhala zosalondola komanso zosakhazikika panthawi ya atomization.Pofotokozalanthanum kloridemu lawi lamoto, kukhazikika kwa zinthu izi kumachulukitsidwa, zomwe zimapangitsa kuti pakhale zotsatira zowunikira zodalirika komanso zobwerezabwereza.
Ndikofunika kuzindikira kuti kusankha kwa mankhwala osinthika, kuphatikizapolanthanum kloride, zimatengera chinthu chomwe chikuwunikidwa.Zinthu zosiyanasiyana zimatha kukhala ndi zofunikira zosiyanasiyana ndikuyankha mosiyana ndi kukhalapo kwa zosintha zamankhwala.Choncho, kuti mupeze zotsatira zowunikira zolondola, m'pofunika kumvetsetsa bwino chitsanzo chomwe chikuwunikidwa ndikusankha zosintha zoyenera za mankhwala.
Pomaliza,lanthanum klorideimagwira ntchito yofunikira ngati kusintha kwamankhwala mu AAS.Ntchito yake yayikulu ndikuletsa mapangidwe azitsulo zosasunthika, kukulitsa chidwi cha kusanthula, ndikuwongolera kukhazikika kwazinthu zina.Pogwiritsa ntchitolanthanum kloridemu AAS, ofufuza ndi akatswiri atha kupeza miyeso yolondola komanso yodalirika, kuwalola kuti afufuze mozama m'madera kuyambira kuyang'anira chilengedwe kupita ku kafukufuku wamankhwala.Kupita patsogolo kosalekeza kwaukadaulo wa AAS komanso kugwiritsa ntchito zosintha zamakina zogwira mtima mongalanthanum kloridezasintha kwambiri kulondola komanso kukhudzidwa kwa kusanthula koyambira.
