Nyob rau hauv-situ tsom xam ntawm cov khoom tsis ruaj khov thiab kev saib xyuas hauv online spectral tau dhau los ua txoj kev tshawb fawb nkaus xwb
Hauv qee cov tshuaj tiv thaiv nitration, cov kua qaub muaj zog xws li nitric acid yuav tsum tau siv los ua cov khoom siv nitrate los tsim cov khoom siv nitration.Cov khoom nitration ntawm cov tshuaj tiv thaiv no tsis ruaj khov thiab yooj yim decomposes.Txhawm rau kom tau txais cov khoom lag luam, tag nrho cov tshuaj tiv thaiv yuav tsum tau ua nyob rau hauv ib puag ncig ntawm -60 ° C.Yog tias cov txheej txheem kev sim offline xws li chromatography, huab hwm coj spectrometry, thiab nuclear magnetic resonance yog siv los soj ntsuam cov khoom, cov khoom yuav decompose thaum lub sij hawm soj ntsuam cov txheej txheem thiab cov ntaub ntawv tseeb hais txog cov tshuaj tiv thaiv tsis tau.Siv online spectroscopy thev naus laus zis rau kev saib xyuas hauv-situ real-time, cov ntsiab lus sib txawv ntawm cov khoom lag luam thiab kev nce qib ntawm cov tshuaj tiv thaiv yog pom tseeb ntawm ib nrais muag.Hauv kev kawm txog cov kev cuam tshuam zoo li no uas muaj cov khoom tsis ruaj khov, kev soj ntsuam online thev naus laus zis yuav luag tsuas yog cov txheej txheem tshawb fawb zoo xwb.
Daim duab saum toj no sau cov kev soj ntsuam online hauv lub sijhawm tiag tiag ntawm cov tshuaj tiv thaiv nitrification.Cov yam ntxwv ncov ntawm cov khoom ntawm txoj haujlwm 954 thiab 1076 cm-1qhia meej cov txheej txheem ntawm kev txhim kho thiab txo qis hauv lub sijhawm, uas qhia tau hais tias ntev dhau lub sijhawm tshuaj tiv thaiv yuav ua rau decomposition ntawm nitration khoom.Ntawm qhov tod tes, lub ncov cheeb tsam ntawm cov yam ntxwv ncov qhia txog cov ntsiab lus ntawm cov khoom hauv qhov system.Los ntawm cov ntaub ntawv soj ntsuam online, nws tuaj yeem pom tias cov khoom lag luam cov ntsiab lus yog qhov siab tshaj plaws thaum cov tshuaj tiv thaiv mus txog 40 feeb, qhia tias 40 feeb yog qhov pom kev zoo kawg nkaus.
