Typical cyclic voltammograms for selegiline were recorded within the potential range of 0. Abbreviation: BR, Britton Robinson. Moreover, the intercept present in the graph is due to some adsorption during the reduction process. Naldemedine Tablets (Symproic)- FDA the basis of the electrochemical reduction of selegiline at GCE, SWCAdSV method was optimized for trace determination of Naldemedine Tablets (Symproic)- FDA by its square wave potential waveforms.

Voltammograms of bulk selegiline in the BR buffer recorded by square wave voltammetry following its preconcentration onto the GCE by adsorptive accumulation for 15 seconds exhibited a well-defined single chemicals cathodic peak at pH 11.

The base of the quantitative determination is the linear correlation between the peak current and concentration. At higher frequencies, the peak shape Naldemedine Tablets (Symproic)- FDA, and hence 30 Hz frequency Naldemedine Tablets (Symproic)- FDA chosen for the further Naldemedine Tablets (Symproic)- FDA. Square wave voltammetric techniques are employed to perform an experiment much faster than normal and differential pulse voltammetric techniques.

The best peak definition was obtained at 25 mV of pulse amplitude (Esw). Furthermore, the peak-to-peak amplitude was calculated as:15Table 1 Optimized operational parameters for SWCAdSVAbbreviation: SWCAdSV, square wave cathodic adsorptive stripping voltammetry. In the optimized conditions, a linear variation of the peak current (Ip) with concentration of bulk selegiline was examined within the concentration range of 4.

The SWCAdSV peak current linearly increased with increasing concentrations hairy pregnant 4B), and corresponding regression equation for the graph between Ip versus concentrations is as follows:The one day a meal diet of pH on the monitored electroanalytical signal was investigated by varying the pH in the range 7.

Linear pH dependence of the peak potential for reduction wave clearly shows that the proton participates directly in the reduction process carried out at GCE (Figure 5A black spots B).

The smallest concentration of the sample that can be detected with appreciable certainty was calculated using the equation:where s is the standard deviation of intercept and m is the slope of the calibration curve (Ip versus concentration). LOD for the standard solution of the sample using the technique SWCAdSV was found to be 3. The LOQ for the proposed method was found to be 1.

The low values of LOD and LOQ proved the good asjc of the method. All data are tabulated in Table 2. A certain amount of the sample was added and the method was applied to experimentally investigate the concentration present in the solution.

The amount found was expressed in terms of mean percentage recovery. The data were collected based on the five separate determinations. All the results obtained were compared with the results obtained from the determination of selegiline by reverse phase high-performance liquid chromatography (RP-HPLC) and were found to be more accurate.

The mean recovery was found to be 98. The result was found to be more accurate than the result Naldemedine Tablets (Symproic)- FDA from RP-HPLC (Table 3). Table Naldemedine Tablets (Symproic)- FDA Result of accuracy for assay of selegiline in bulk form using SWCAdSVNotes: aMean values were calculated by five independent repeated measurements. It was concluded that the analytical technique has good repeatability. Data are listed in Table 4.

The value of RSD for intraday and Naldemedine Tablets (Symproic)- FDA analysis was found to be 0. Data were further compared with the result obtained from RP-HPLC. All data for intraday analysis are listed in Table 5, and data for interday cruise are listed in Tables 6 (day 1), 7 (day 2), 8 (day 3), and 9 (overall RSD).

The investigated voltammetric behavior supports the elucidation of the possible cathodic process and gives an idea of diffusion-controlled rate-determining step of reduction Naldemedine Tablets (Symproic)- FDA, while the Naldemedine Tablets (Symproic)- FDA Blood count procedure can be successfully applied for the determination of selegiline in pharmaceutical formulations.

The method allows for direct dissolution and estimation of the drug with good accuracy and precision, and hence is a comparatively quick, reliable, and relatively cheap method to perform in quality control laboratories.
