Spectrophotometric Determination of Cephalosporins in Pharmaceutical Samples

Spectrophotometric Determination of Salicylamide and Paracetamol in Biological Samples and Pharmaceutical Formulations by a Differential Kinetic Method

A rapid, simple and sensitive spectrophotometric method is presented for the determinations of salicylamide and paracetamol in mixture. The method is based on their complexation and oxidation reactions by Fe ion. Two sets of conditions were established such that in one set of conditions only salicylamide reacts with Fe ion, but in the other set of conditions both of the salicylamide and paracet...

Spectrophotometric Determination of Promethazine Hydrochloride and Paracetamol in Pharmaceutical Tablets

Spectrophotometric techniques were developed for the determination of single and binarymixture Promethazine hydrochloride (PMH) and Paracetamol (PCM). Normal and first derivative (D) used for single drug at λ 249.5 and 243.0 for PMH and 243.5 and 225 for PCM. The simultaneous determination of binary mixture (PMH) and (PCM) were accomplished by first derivative (D) and second derivative (D) spec...

A Highly Sensitive Kinetic Spectrophotometric Method for the Determination of Ascorbic Acid in Pharmaceutical Samples

In this study, a new reaction system for quantitative determination of ascorbic acid was introduced. The developed method is based on inhibitory effect of ascorbic acid on the Orange G-bromate system. The change in absorbance was followed spectrophotometrically at 478 nm. The dependence of sensitivity on the reaction variables including reagents concentration, temperature and time was investiga...
