Flow injection spectrophotometric determination of paracetamol (acetaminophen) in pharmaceutical formulations.

The method is based on the reduction of nicardipine and isradipine with zinc powder and calcium chloride followed by further reduction with sodium pentacyanoaminoferrate (II) to give

A freqüência analítica foi 42 h -1 e os sinais transientes em triplicata obtidos para as soluções de referência de riboflavina e aqueles em triplicata para as solu- ções de

sinais transientes obtidos para aquelas soluções de referência de cloridrato de piridoxina e soluções de amostras são apresen- tados na Figura 4.

Como método comparativo, empregou-se o procedimento espectrofotométrico descrito na Farmacopéia Americana (USP-21) [16] baseado na mesma reação entre paracetamol e nitrito, em

The paracetamol determination was per- formed using the developed spectrophotometric flow injection method and the results obtained were compared with those obtained using a
