Kev sib xyaw ua ke cuam tshuam qhov nqus tau zoo ib yam li txoj kev ntev. … Raws li qhov kev xav tau nce, muaj ntau cov molecules hauv cov tshuaj, thiab ntau lub teeb raug thaiv. Qhov no ua rau kev daws teeb meem tsaus dua vim tias lub teeb tsawg dua tuaj yeem dhau mus.
Vim li cas thiaj nce concentration nce absorbance?
Qhov no yog vim qhov sib faib ntawm lub teeb uas tau nqus tau cuam tshuam los ntawm tus lej ntawm cov molecules uas nws cuam tshuam nrog. Cov kev daws teeb meem uas muaj ntau dua muaj ntau cov molecules uas cuam tshuam nrog lub teeb uas nkag mus, yog li ua kom nws nqus tau.
Puas absorbance nyob ntawm qhov concentration?
Qhov nqus yog ncaj qha proportional rau qhov concentration (c) ntawm kev daws ntawm cov qauv siv hauv kev sim. Lub absorbance yog ncaj qha proportional rau qhov ntev ntawm lub teeb txoj kev (l), uas yog sib npaug zos rau qhov dav ntawm lub cuvette.
Dab tsi yog absorbance tiv thaiv concentration?
Introduction: Raws li Beer Txoj Cai, A=Ebc, nyob rau hauv cov xwm txheej zoo tagnrho, cov tshuaj muaj zog thiab nws cov absorbance yog ncaj qha proportional: ib tug high-concentration tov absorbs ntau lub teeb, thiab kev daws ntawm qis concentration absorbs tsawg lub teeb.
Dab tsi cuam tshuam rau kev nqus?
Rau ib qho piv txwv, absorbance nyob ntawm 6 yam: (1) tus kheej ntawm absorbing . substance, (2) nws concentration, (3)lub pathlength i, (4) thiab wavelength ntawm lub teeb, (5) tus kheej ntawm lub. hnyav, thiab (6) qhov kub thiab txias.
