Cold Vapor Atomic Absorption Spectroscopy lossis CVAAS yog ib qho ntawm cov txheej txheem tseem ceeb rau kev tshuaj ntsuam mercury … Qhov ntau ntawm cov tshuaj muaj nyob hauv cov qauv ib puag ncig.

Dab tsi yog qhov txias vapor atomic absorption spectroscopy?

Txhais: A hom atomic absorption spectrometry uas tsis tas yuav tsum muaj vaporisation kauj ruamvim tias cov qauv yog cov hlau hnyav hnyav xws li mercury, uas yog vapor ntawm chav tsev kub.

Puas yog cov txheej txheem txias vapor siv rau kev ntsuas ntawm lwm cov hlau?

Siv hauv kev ntsuas cov lej ntawm cov hlau hnyav hnyav xws li mercury, txias vapor AFS ua rau siv cov yam ntxwv tshwj xeeb ntawm mercury uas tso cai rau ntsuas vapor ntawm chav tsev kub.… Qhov no preconcentrates cov mercury, nce rhiab heev, thiab kuj hloov cov mercury mus rau hauv inert gas.

Lub hauv paus ntsiab lus ntawm atomic absorption spectroscopy yog dab tsi?

AAS yog cov txheej txheem tshuaj xyuas siv los txiav txim siab ntau npaum li cas ntawm qee yam hauv cov qauv. Nws siv lub hauv paus ntsiab lus hais tias atoms (thiab ions) tuaj yeem nqus lub teeb ntawm qhov tshwj xeeb, qhov tshwj xeeb wavelengthThaum qhov tshwj xeeb wavelength ntawm lub teeb tau muab, lub zog (lub teeb) yog absorbed los ntawm lub atom.

Vim vapor txias hu li cas?

evaporation pos tsim thaum dej vapor ntxiv rau huab cua uas txias dua li qhov vapor qhov chaw; Feem ntau, thaum huab cua txias heev drifts hla cov dej sov; kuj hu ua sea smoke.
