Waa maxay Eriochrome Black T CAS 1787-61-7?

Tilmaamaha Madow ee Eriochrome, oo sidoo kale loo yaqaan mordye black 11, oo loo yaqaan Elai Chrome black T indicator, magaca sayniska 1-(1-hydroxy-2-naphthol azo) -6-nitro-2-naphthol - 4-sulfonate sodium milix, waa tilmaame dhammaystiran oo lagu go'aaminayo barium, cadmium, indium, magnesium, manganese, calcium, lead, scandium, strontium, zinc, zirconium, iwm. Go'aaminta adkaanta guud ee muunadda biyaha (wadarta guud ee kaalshiyamka iyo magnesium ions) ayaa sidoo kale loo isticmaalaa tilmaame chromium Chemicalbook black T indicator. Markii aan diyaarinay tilmaamaha T madow ee chromium sida ku xusan Xeerka nadaafadda ee Biyaha Cabitaanka 2001, waxaan ogaanay in 9.1.3.6, 95% ethanol oo keliya loo isticmaalay in lagu milmo tilmaamaha T madow ee chrome oo lagu qaso 100ml, si tilmaame la helay uu u noqdo casaan guduudan oo madow oo leh muunadda biyaha iyo xalka xaqiijinta biyaha saafiga ah siday u kala horreeyaan, midabka barta dhammaadka titration-kana lama beddeli karo.
