Iyini i-Eriochrome Black T CAS 1787-61-7?

Inkomba ye-Eriochrome Black T, eyaziwa nangokuthi i-mordye black 11, eyaziwa nangokuthi i-Elai Chrome black T indicator, igama lesayensi elithi 1-(1-hydroxy-2-naphthol azo) -6-nitro-2-naphthol - 4-sulfonate sodium salt, iyinkomba ephelele yokunquma i-barium, i-cadmium, i-indium, i-magnesium, i-manganese, i-calcium, i-lead, i-scandium, i-strontium, i-zinc, i-zirconium, njll. Ukunquma ubulukhuni obuphelele besampula yamanzi (inani eliphelele le-calcium nama-ion e-magnesium) kusetshenziswa futhi njengenkomba yenkomba ye-chromium Chemicalbook black T. Lapho silungiselela inkomba ye-T emnyama ye-chrome ngokwe-Sanitary Code for Drinking Water 2001, sithole ukuthi ku-9.1.3.6, i-ethanol engu-95% kuphela esetshenzisiwe ukuncibilikisa inkomba ye-T emnyama ye-chrome bese iyincibilikisa ibe yi-100ml, ukuze inkomba etholakele ibe bomvu onsomi omnyama nesampula yamanzi kanye nesisombululo sokuqinisekisa amanzi ahlanzekile ngokulandelana, futhi umbala wephuzu lokugcina le-titration awukwazi ukushintshwa.
