Eriochrome Black T CAS 1787-61-7 yog dab tsi?

Tus qhia Eriochrome Black T, tseem hu ua mordye black 11, alias Elai Chrome black T, lub npe scientific 1-(1-hydroxy-2-naphthol azo) -6-nitro-2-naphthol - 4-sulfonate sodium ntsev, yog ib qho qhia txog kev txiav txim siab ntawm barium, cadmium, indium, magnesium, manganese, calcium, lead, scandium, strontium, zinc, zirconium, thiab lwm yam. Kev txiav txim siab ntawm tag nrho cov dej tawv (tag nrho cov calcium thiab magnesium ions) kuj siv ua qhov qhia txog chromium Chemicalbook black T. Thaum peb npaj qhov qhia chrome black T raws li Sanitary Code for Drinking Water 2001, peb pom tias hauv 9.1.3.6, tsuas yog 95% ethanol siv los yaj qhov qhia chrome black T thiab dilute nws mus rau 100ml, yog li ntawd qhov qhia tau txais yog xim av tsaus liab nrog cov dej qauv thiab cov dej ntshiab, thiab xim ntawm qhov kawg titration tsis tuaj yeem hloov pauv.
