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

Isalathisi se-Eriochrome Black T, esaziwa ngokuba yi-mordye black 11, eyaziwa ngokuba yi-Elai Chrome black T indicator, igama lesayensi elithi 1-(1-hydroxy-2-naphthol azo) -6-nitro-2-naphthol - 4-sulfonate sodium salt, sisalathisi esibanzi sokumisela i-barium, i-cadmium, i-indium, i-magnesium, i-manganese, i-calcium, i-lead, i-scandium, i-strontium, i-zinc, i-zirconium, njl. Ukumisela ubunzima obupheleleyo besampuli yamanzi (isixa sipheleleyo se-calcium kunye ne-magnesium ions) kukwasetyenziswa njengesalathisi se-chromium Chemicalbook black T indicator. Xa sasilungiselela isalathisi se-chrome black T ngokwe-sanitary Code for Drinking Water 2001, safumanisa ukuba kwi-9.1.3.6, yi-95% ye-ethanol kuphela eyasetyenziswa ukunyibilikisa isibonakaliso se-chrome black T kwaye siyinyibilikise ukuya kwi-100ml, ukuze isalathisi esifunyenweyo sibe bomvu omfusa omnyama kunye nesampuli yamanzi kunye nesisombululo sokuqinisekisa amanzi acocekileyo ngokulandelelanayo, kwaye umbala wesiphelo se-titration awunakutshintshwa.
