Kev kho cov dej khib nyiab Nitrobenzene los ntawm Electrocatalytic Oxidation Reactor nrog Hluav Taws Kub Kub Tube Electroplating

The correlation analysis of the relative residual concentration of nitrobenzene with time t under different initial concentrations and current intensities in Figures 7 and 8 using a univariate linear regression equation shows that the correlation coefficient of the first-order regression equation is greater than the critical correlation coefficient (R>0.95), qhia tias qhov txo qis ntawm nitrobenzene concentration nrog lub sij hawm degradation ua raws li qhov pom tseeb thawj-txiav txim siab kinetics qauv. Thawj qhov kev txiav txim tus nqi tas li K yog qhia hauv Cov Lus 2 thiab 3. Cov ntaub ntawv hauv Cov Lus 2 thiab 3 qhia tau hais tias nyob rau hauv cov kev mob tshwm sim ntawm qhov kev sim no, oxidation degradation tus nqi tas li ntawm nitrobenzene nce nrog qhov nce ntawm thawj zaug concentration thiab tam sim no siv.

Daim ntawv thov ntawm SPSS software los soj ntsuam cov ntaub ntawv nyob rau hauv daim duab 7 thiab 8 qhia tau hais tias thaum xub thawj concentrations ntawm 36.82mg/L thiab 139.58mg/L, kev sib raug zoo ntawm lub sij hawm thiab ln (C0/C) yog heev tseem ceeb ( p<0.01), and at initial concentrations of 261.85mg/L, the correlation between time and ln (C0/C) is significant (p<0.05). Under different current intensities, the correlation between time and ln (C0/C) was significant (p<0.05). So, at different initial concentrations and current intensities, the correlation between ln (C0/C) and time is significant, indicating that the initial concentration and current intensity have a significant impact on the degradation of nitrobenzene.

Txoj kev tshawb fawb txog kev kho cov dej khib nyiab nitrobenzene siv electrocatalytic oxidation reactor qhia tau hais tias:

(1) Kev kho cov nyhuv ntawm nitrobenzene cov dej khib nyiab siv cov pa roj carbon lim dej electrode adsorption txoj kev yog qhov zoo dua li cov txheej txheem electrolysis thiab activated carbon adsorption.

(2) Cov thev naus laus zis no tuaj yeem txhim kho tus nqi tshem tawm nitrobenzene hauv cov dej khib nyiab, thiab qhov kev siv tam sim no thiab cov dej nyoos muaj kev cuam tshuam loj heev rau kev degradation ntawm nitrobenzene. Raws li qhov kev siv tam sim no nce, qhov kev tshem tawm ntawm nitrobenzene sib npaug nce. Raws li cov xwm txheej ntawm qhov kev sim no, qhov kev tshem tawm ntawm nitrobenzene mus txog 98 feem pua ​​thaum qhov kev siv tam sim no tau nce mus rau 2.0A. Qhov nce hauv cov concentration ntawm cov dej nyoos hauv cov dej khib nyiab nitrobenzene muaj txiaj ntsig zoo rau cov tshuaj tiv thaiv electrocatalytic, thiab kev tshem tawm ntawm nitrobenzene kuj nce ntxiv. Lub sijhawm nyob ntawm cov dej khib nyiab nitrobenzene hauv reactor kuj cuam tshuam rau tus nqi tshem tawm. Feem ntau hais lus, ncua sij hawm nyob hauv tsev yog qhov zoo rau kev txhim kho tus nqi tshem tawm.

(3) Lub electrocatalytic oxidation degradation ntawm nitrobenzene ua raws li qhov pom tseeb thawj-txiav txim siab kinetics qauv. Cov thev naus laus zis no muaj peev xwm txhim kho tau zoo rau kev kho mob siab thiab nyuaj rau degrade organic pollutants, thiab kev tshawb fawb ntxiv thiab kev txhim kho tuaj yeem tsim cov cuab yeej siv kho dej khib nyiab.
