Determination of Ascorbic Acid in Vegetables by Derivative Spectrophotometry

Determination of ascorbic acid (AA) in garlic, green pepper and chestnut was performed by derivative spectrophotometry without using any pre-separation or background correction techniques. The method is based on the measurement of the distances between two extremum values (peak-to-peak amplitudes) in second and third order derivative spectra of the extracts. Ten percent trichloroacetic acid was...

Simultaneous determination of titanium and molybdenum in alloy steels using derivative spectrophotometry in neutral micellar medium

A simple, selective and sensitive spectrophotometric method has been developed for the individual and simultaneous determination of Ti(IV) and Mo(VI) using salicylaldehyde p-hydroxybenzoylhydrazone (SAPHBH) in presence of Triton X100, without any prior separation. Beer’s law is obeyed between 0.15-2.0 and 0.20-2.51 μgmL concentration of Ti(IV) and Mo(VI) at 470 and 410 nm, respectively. The mol...

Second derivative spectrophotometry for simultaneous determination of iron (II) and copper (II) using 2-ketobutyric acid thiosemicarbazone

A new chromophoric reagent, 2-ketobutyric acid thiosemicarbazone (KBAT) has been used for the simultaneous determination of iron, copper and vanadium. KBAT forms yellowish-green and blue complexes with iron (II) and copper (II) respectively at pH 6.5 and a yellow complex with vanadium (V) at pH 5.5. Calibration graphs for the individual determinations by second derivative spectrophotometry were...

Determination of azole antifungal medicines using zero-order and derivative UV spectrophotometry.

This paper presents a new methodology of quantitative determination of seven azole antifungal medicines widely used in therapy. Analyses were performed directly by using zero-order (fluconazole), first derivative (bifonazole, clotrimazole, econazole, itraconazole, miconazole) and second derivative (ketoconazole) UV spectrophotometry. Validation of all methods confirms their proper precision (%R...
