Cov kev siv ntawm diphenylcarbazide hauv dej tshuaj
Cov versatility ntawm covdiphenylcarbazide reasent yog pom tseeb nyob rau hauv nws ntau ntawm cov kev siv hauv kev tsom xam cov dej zoo. Nov yog qee qhov kev siv feem ntau:
Thawj daim ntawv thov ntawm Diphenylcarbazide yog nyob rau hauv kev kuaj pom thiab kom muaj nuj nqis ntawm hexavalent chromium (CR (vi)) hauv cov qauv dej. Hexavalent Chromium yog daim qauv tshuaj lom ntawm daim chromium uas tuaj yeem ua rau muaj teeb meem kev noj qab haus huv, suav nrog cov qog noj ntshav, yog tias noj ntau yam. Txoj kev diphenylcarbazide yog qhov ua tau zoo rau lub hom phiaj no uas nws tau saws raws li cov txheej txheem tiv thaiv cov txheej txheem thoob ntiaj teb.
Thaum diphenylcarbazide reacts nrog cr (vi) hauv kev daws acidic, nws tsim cov xim liab-xim av. Qhov siv ntawm cov xim no ncaj qha ncaj qha rau cov kev xav ntawm CR (VI) hauv cov qauv, tso cai rau qhov tseeb ntawm kev tsom xam spectrophotometric.
Kev lag luam xws li cov elecoplating, tawv tanning, tawv tanning, tawv nqaij tsim tau feem ntau siv chromium tebchaw hauv lawv cov txheej txheem. Cov kev lag luam no yuav tsum saib xyuas lawv cov effluents rau chromium cov ntsiab lus ua ntej tawm. Cov kev ntsuam xyuas diphenylcarbazide muab cov txheej txheem ceev thiab ntseeg tau rau qhov kev coj ua niaj hnub no, pab kev lag luam ua raws li ib puag ncig kev cai.
Kev Kuaj Dej Hauv Av thiab Kev Ntsuas Cov Dej Deg & Cov Dej Haus Cov Dej Tswjhwm Zoo & Kev Kho Mob Txheej Txheem Kev Tswj Xyuas
Cov koom haum ib puag ncig thiab cov kws tshawb nrhiav siv Diphenylcarbazide los ntsuas cov tshuaj chromium hauv lub cev. Qhov no yog qhov tshwj xeeb tshaj yog nyob hauv thaj chaw muaj kev muaj thaj chaw muaj thaj chaw lossis cov chaw muaj kev sib kis. Kev xeem ib txwm yuav pab taug qab cov kuab paug thiab siv kho cov tshuaj kho thaum tsim nyog.
Kev ua kom cov khoom siv hluav taws xob feem ntau txuas cov kev sim pov tseg pov hwm diphenylcarbazide hauv lawv cov kev tswj hwm zoo. Thaum chromium tsis yog ib txwm muaj kev txhawj xeeb hauv dej haus, nws txoj kev saib xyuas yog qhov tseem ceeb kom ua raws li cov qauv kev noj qab haus huv thiab txhawm rau txhawm rau qee yam yuav tsis muaj peev xwm ua kom ntxov.
Nyob rau hauv cov khoom siv dej khib nyiab uas cuam tshuam nrog chromium-muaj effluents, diphenylcarbazide kev xeem yog siv los saib xyuas kev ua haujlwm ntawm chromium tshem tawm cov txheej txheem. Qhov no pab ua haujlwm ua kom muaj kev kho kom zoo thiab ua kom pom tau tias cov dej kho kom haum raws cov qauv kev tawm tsam.
Thaum ua kev ntsuas ib puag ncig rau cov haujlwm muaj kev lag luam tshiab lossis ntsuas cov haujlwm chrominal yog feem ntau kuaj cov dej zoo. Qhov no pab hauv kev txheeb xyuas qhov muaj peev xwm lossis qhov cuam tshuam tiag tiag ntawm kev lag luam cov haujlwm ntawm cov khoom siv hauv cov dej hauv cov dej hauv cov chaw nyob hauv ib cheeb tsam.
Hauv kev kawm thiab kev tshawb fawb kev tshawb fawb chaw, diphenylcarbazide yog siv tsis tsuas yog rau cov qauv chromium tab sis kuj tseem ua tus qauv rau kev tsim cov txuj ci tshiab. Nws cov kev nkag siab zoo rau kev nkag siab chemistry ua rau nws muaj qhov sib piv rau kev sib piv cov hau kev tshiab lossis cov twj paj nruag.
Qhov dav dav siv ntawm diphenylcarbazide hauv cov ntawv thov no underscores nws qhov tseem ceeb hauv kev tsom xam cov dej zoo. Nws txoj kev ntseeg tau, rhiab heev, thiab yooj yim ntawm kev siv ua rau nws mus rau txoj haujlwm chromium thoob plaws ntau yam kev tiv thaiv ntau yam kev tiv thaiv ntau yam.
