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

Eriochrome Black T isalathisi, eyaziwa ngokuba mordye black 11, alias Elai Chrome emnyama T isalathisi, igama lenzululwazi 1-(1-hydroxy-2-naphthol azo) -6-nitro-2-naphthol - 4-sulfonate sodium ityuwa, i a isalathisi esibanzi sokumiselwa kwe-barium, i-cadmium, i-indium, i-magnesium, i-manganese, i-calcium, i-load, i-scandium, i-strontium, i-zinc, i-zirconium, njl. ikwasetyenziswa njengesalathisi se-chromium Chemicalbook emnyama T isalathisi. Xa silungiselela i-chrome emnyama T isalathisi ngokwemigaqo ye-sanitary yaManzi okusela ka-2001, safumanisa ukuba kwi-9.1.3.6, kuphela i-ethanol engama-95% yayisetyenziselwa ukunyibilikisa isalathisi esimnyama se-chrome kwaye siyihlambulule kwi-100ml, ukwenzela ukuba isalathisi esifunyenweyo. yayimnyama emfusa ebomvu kunye nesampulu yamanzi kunye nesisombululo sokuqinisekisa amanzi acocekileyo ngokulandelelana, kwaye umbala wendawo yokuphela kwe-titration awunakuguqulwa.
