1.Product Overview:
Lub ntsuas ntsuas tuaj yeem ua haujlwm tsis tu ncua thiab ua haujlwm tsis tu ncua ntev ntev raws li qhov chaw teeb tsa, thiab tau siv dav hauv kev lag luam muaj kuab paug paug tawm cov dej khib nyiab, cov txheej txheem dej khib nyiab, cov dej phwj tuaj kho cov dej phwj tuaj, cov kav dej phwj tuaj kho cov dej phwj tuaj thiab lwm lub sijhawm. Raws li qhov nyuaj ntawm cov kev xeem hauv cheeb tsam, cov txheej txheem ua ntej tuaj yeem raug xaiv los ua kom ntseeg tau ntawm cov txheej txheem xeem thiab qhov tseeb ntawm qhov kev xeem, thiab ua tau raws li qhov xav tau ntawm thaj chaw sib txawv.
2.Product Principles:
Cov khoom no yog txiav txim los ntawm dibenzoyl dihydrazine spectrophotometric. Tom qab sib xyaw cov qauv dej thiab cov oxidants muaj zog, trivalent chromium yog oxidized rau hexavalent chromium. Hexavalent chromium reacts nrog qhov taw qhia los tsim cov xim sib txawv nyob rau hauv lub xub ntiag ntawm acidic ib puag ncig thiab qhov taw qhia. Lub ntsuas ntsuas ntsuas qhov kev hloov ntawm cov xim thiab hloov qhov kev hloov pauv no mus rau tag nrho cov txiaj ntsig chromium. Tus nqi ntawm cov xim uas tsim tawm yog sib npaug rau tag nrho cov nyiaj ntawm chromium.
Txoj kev no yog tsim rau cov dej khib nyiab nrog tag nrho cov chromium hauv thaj tsam ntawm 0 ~ 500mg / L.
