Spectrophotometric 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...
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 کاملPerformance Evaluation of a Novel Potentiometric Membrane Sensor for Determination of Atorvastatin in Pharmaceutical Preparations
A novel potentiometric ion-selective PVC membrane sensor for analysis of atorvastatin (AT) in pharmaceutical preparations based on atorvastatin-(tetraphenyl borate), (AT-(TPB)2) as sensing element, tetraphenyl borate as additive and tris-2-ethyl-hexyl phosphate (TOP) as plasticizer solvent was prepared. The electrode shows a good Nernestian response over the concentration range of 0.09–5586 µ...

متن کاملpolarographic determination of certain cephalosporins in pharmaceutical preparations
polarographic methods have been developed for the determination of two cephalosporins namely cefotaxime (ctx) and ceftriaxone (ctr) in pharmaceutical formulations. well defined peaks at potentials –1.432 v vs. sce for ctx and –1.627 v vs. sce for ctr were obtained in the presence of tungsten (vi). the method has been successfully applied for the determination of above mentioned cephalosporins i...
