Popis: |
A simple and fast spectrophotometric method for the determination of bismuth in pharmaceutical preparations is described. The used chromatic reactive is 1-[di(2-pyridyl)methylene]-5-salicilydene-thiocarbonohydrazide+ ++ forming a yellow complex with bismuth. In a solution containing 40% v/v of dimethylformamide molar absorption is 5.7 x 10(4) l.mol-1.cm-1 at 421 nm and at pH 4.3. The optimal conditions for the color development and the possible interferences are studied. |
