متن کاملSpectrophotometric Determination of Metronidazole in Pharmaceutical Preparations
A rapid and sensitive spectrophotometric method is proposed for determination of Metronidazole. The method depends on the reduction of Metronidazole molecule with zinc dust and hydrochloric acid flowed by diazotation and coupling with 8-quinolinol to give colored chromogens easily measured spectrophotometrically which has λmax= 437 nm. The experimental conditions were optimized and berr’s law w...
متن کاملSpectrophotometric Determination of Diclofenac in Pharmaceutical Preparations
Neste trabalho é proposto um método espectrofotométrico modificado para a determinação de diclofenaco em preparações farmacêuticas. Usa-se solução de cobre(II) como reagente, o que leva à formação de um complexo cobre(II)-diclofenaco de cor verde, com máximo de absorção em 680 nm. Foram estudadas as influências: do pH; da concentração de cobre(II); do uso de ácido acético na solução de cobre(II...
