Lanthanum chloride, feem ntau hu uaLaCl3, yog ib qho kev sib xyaw nrog ntau yam kev siv hauv kev tshawb fawb thiab kev lag luam.Ib qho ntawm nws txoj haujlwm tseem ceeb yog nyob rau hauv thaj tsam ntawm atomic absorption spectroscopy (AAS), qhov uas nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov raug thiab rhiab ntawm kev tsom xam.AAS yog cov txheej txheem kev tshuaj xyuas siv los txiav txim siab cov ntsiab lus hauv cov qauv.Cia peb saib ze dua ntawm lub luag haujlwm ntawmlanthanum chloridehauv atomic absorption spectroscopy thiab nkag siab nws qhov tseem ceeb.
AAS yog dav siv nyob rau hauv ntau lub lag luam, nrog rau kev saib xyuas ib puag ncig, tshuaj, kev ua liaj ua teb, metallurgy, thiab lwm yam. Nws yog ib qho txheej txheem uas siv atoms nqus thiab emit lub teeb los kuaj thiab ntsuas cov khoom sib txawv hauv cov qauv muab.Cov cuab yeej siv hauv AAS muaj ntau yam khoom siv, suav nrog lub hollow cathode teeb nrog lub ntsiab lus ntawm kev txaus siab, ib lub nebulizer, ib lub monochromator, lub raj photomultiplier, thiab thaum kawg yog lub tshuab ntes.
Lanthanum chlorideFeem ntau yog siv los ua tshuaj hloov kho hauv atomic absorption spectrometry.Cov tshuaj hloov pauv tshuaj yog cov tshuaj ntxiv rau cov qauv lossis cov nplaim hluav taws los txhim kho qhov ruaj khov ntawm cov khoom raug tshuaj xyuas thiab txhim kho kev ntsuas qhov rhiab heev.Hauv atomic absorption spectrometry, ib qho me me ntawmlanthanum chloridefeem ntau yog ntxiv rau cov nplaim taws hauv kev daws teeb meem.Los ntawm kev ua li ntawd, nws tsim cov complexes nrog qee cov ntsiab lus, tiv thaiv lawv los ntawm kev sib cuam tshuam nrog lwm cov khoom muaj nyob hauv cov qauv.
Ib qho ntawm cov haujlwm tseem ceeb ntawmlanthanum chlorideNyob rau hauv atomic absorption spectrometry yog inhibit qhov tsim ntawm non-volatile hlau oxides.Thaum cov qauv nkag mus rau hauv cov nplaim taws, nws evaporates thiab atomizes.Qee lub ntsiab lus zoo li tsim oxides uas nyuaj rau evaporate, ua rau qhov ntsuas tsis raug.Lanthanum chloride ua raws li kev thaiv, tiv thaiv kev tsim ntawm cov oxides thiab ua kom muaj kev ruaj ntseg ntawm cov khoom.
Ntxiv nrog rau inhibiting kev tsim cov oxides,lanthanum chloridetuaj yeem ua kom qhov kev xav tau ntawm kev tsom xam.Nws ua qhov no los ntawm kev ua kom cov ionization efficiency ntawm cov tshuaj ntsuam xyuas cov ntsiab lus, uas ua rau lub teeb liab zoo zog.Qhov no rhiab heev rhiab heev enables nrhiav kom tau thiab kom muaj nuj nqis ntawm kab kawm txawm nyob rau hauv complex matrices.Lub peev xwm los ntsuas qhov tsis tshua muaj siab yog qhov tseem ceeb hauv ntau yam kev siv, xws li kev txheeb xyuas ib puag ncig, qhov uas muaj cov kab mob sib kis tuaj yeem muaj kev cuam tshuam loj.
Ntxiv thiab,lanthanum chloridepaub tias yuav ua rau kom muaj kev ruaj ntseg ntawm qee yam hauv cov nplaim taws.Qee lub ntsiab lus, tshwj xeeb tshaj yog cov uas tsis tshua muaj volatility, yuav muaj qhov tsis zoo thiab kev ruaj ntseg thaum lub sij hawm atomization txheej txheem.Los ntawm kev qhialanthanum chloridemus rau hauv cov nplaim taws, qhov ruaj khov ntawm cov ntsiab lus no tau nce, uas ua rau muaj kev ntseeg siab dua thiab rov ua dua tshiab.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev xaiv cov tshuaj hloov kho, suav nroglanthanum chloride, nyob ntawm cov ntsiab lus tshwj xeeb raug tshuaj xyuas.Cov ntsiab lus sib txawv tuaj yeem muaj cov kev xav tau sib txawv thiab teb txawv rau qhov muaj cov tshuaj hloov pauv.Yog li ntawd, txhawm rau kom tau txais cov txiaj ntsig kev txheeb xyuas tseeb, nws yuav tsum muaj kev nkag siab zoo ntawm cov qauv uas tau txheeb xyuas thiab xaiv cov tshuaj kho kom haum.
Hauv kev xaus,lanthanum chlorideplays lub luag haujlwm tseem ceeb ua tus hloov kho tshuaj hauv AAS.Nws lub luag haujlwm tseem ceeb yog inhibit qhov tsim ntawm cov hlau oxides uas tsis yog-volatile, txhim khu lub rhiab heev ntawm kev tsom xam, thiab txhim kho kev ruaj ntseg ntawm qee yam khoom.Los ntawm kev sivlanthanum chloridehauv AAS, cov kws tshawb fawb thiab cov kws tshuaj ntsuam xyuas tuaj yeem tau txais cov kev ntsuas meej thiab txhim khu kev qha, tso cai rau lawv nkag mus tob rau hauv thaj chaw xws li kev saib xyuas ib puag ncig mus rau kev tshawb fawb tshuaj.Kev nce qib txuas ntxiv ntawm AAS thev naus laus zis thiab kev siv cov tshuaj hloov pauv zoo xws lilanthanum chloridetau zoo heev txhim kho qhov raug thiab rhiab heev ntawm elemental tsom xam.
