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

I-Eriochrome Black T inkomba, eyaziwa nangokuthi i-mordye black 11, i-alias Elai Chrome emnyama T inkomba, igama lesayensi 1-(1-hydroxy-2-naphthol azo) -6-nitro-2-naphthol - 4-sulfonate sodium usawoti, inkomba ebanzi yokunqunywa kwe-barium, i-cadmium, i-indidium, i-calcium, i-magnesium, i-lead, i-zinganese, i-zinganese, i-magnesiamu i-zirconium, njll. Ukunqunywa kobunzima obuphelele besampula yamanzi (inani eliphelele le-calcium ne-magnesium ion) nakho kusetshenziswe njengenkomba ye-chromium Chemicalbook black T inkomba. Lapho silungisa inkomba ye-chrome emnyama ye-T ngokuya ngeSanitary Code for Drinking Water 2001, sathola ukuthi ku-9.1.3.6, i-ethanol engu-95% kuphela yasetshenziswa ukuncibilikisa inkomba ye-chrome emnyama T futhi ihlanjululwe ibe ngu-100ml, ukuze inkomba etholiwe ibe nsomi ngokubomvu ngesampula yamanzi futhi iphoyinti lokuqinisekisa lamanzi elihlanzekile lingakwazi ukuqeda umbala.
