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 ephelele yokunqunywa kwe-barium, i-cadmium, i-indium, i-magnesium, i-manganese, i-calcium, i-lead, i-scandium, i-strontium, i-zinc, i-zirconium, njll. isetshenziswa futhi njengenkomba ye-chromium Chemicalbook black T inkomba. Ngesikhathi silungisa i-chrome black T indicator ngokweSanitary Code for Drinking Water 2001, sathola ukuthi ngo-9.1.3.6, kwasetshenziswa i-ethanol engu-95% kuphela ukuncibilikisa inkomba ye-chrome emnyama T bese ihlanjululwa ibe ngu-100ml, ukuze inkomba etholiwe. ibibomvu ngokumnyama nesampula lamanzi kanye nesixazululo sokuqinisekisa amanzi ahlanzekile ngokulandelana, futhi umbala wephoyinti lokuphela kwe-titration awukwazanga ukushintshwa.
