Electrochemical Behavior and Highly Sensitive Voltammetric Determination of Doxepin in Pharmaceutical Preparations and Blood Serum Using Carbon Ionic Liquid Electrode
In this manuscript, the electrocatalytic oxidation of doxepin (DOX) was studied at a carbon ionic liquid electrode, fabricated using graphite, and the ionic liquid 1-octylpyridinium hexaflourophosphate (OPFP). The surface of the proposed electrode was characterized by scanning electron microscopy. Differential pulse voltammetry was applied as an analytical technique for quantification of sub-mi...

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...
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 کاملDetermination of Paroxetine in Pharmaceutical Preparations Using HPLC with Electrochemical Detection
A reliable and sensitive high performance liquid chromatographic method for the determination of widely prescribed antidepressant has been developed. Paroxetine is a potent selective serotonin reuptake inhibitor used for the treatment of depression and various mood disorders. The optimum mobile phase was prepared using a combination of 40% acetonitrile and phosphate buffer 0.01 M to pH 3 and ru...
