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 ityuwa sodium, luphawu olubanzi ukuzimisela barium, cadmium, indium, calcium, magnesium, i-zinganese, i-lead, i-zinganese, i-zinc, i-zinc, i-magnesium i-zirconium, njl. Ukumiselwa kobunzima obupheleleyo besampulu yamanzi (inani elipheleleyo le-calcium kunye ne-magnesium ion) likwasetyenziswa njengesalathisi se-chromium Chemicalbook emnyama T isalathisi. Xa silungiselela i-chrome emnyama T isalathisi ngokwemigaqo yococeko lwaManzi okuSela ngo-2001, safumanisa ukuba kwi-9.1.3.6, kuphela i-ethanol engama-95% yayisetyenziselwa ukunyibilikisa isalathisi esimnyama se-chrome kwaye siyihlambulule kwi-100ml, ukuze isalathisi esifunyenweyo sibe mnyama omfusa obomvu kunye nesampulu yamanzi kunye nesombululo yamanzi ecocekileyo yokuqinisekisa i-titration, kunye nombala ococekileyo onokuthi utshintshe umbala.
