Effect of conditions on the anodization of Zircaloy-4 in EDTA


ABSTRACT:

Anodization of Zircaloy-4 in EDTA electrolyte has been studied under different anodizing conditions at room temperature. It has been observed that the change of current density and solvent has a marked influence on the kinetics of anodization. The kinetic parameters like rate of formation(dV/dt), ionic current efficiency(Ƞ) and differential field of formation(FD) were calculated. The surface natures of the anodized films were studied from Scanning Electron Micrographs(SEM) under different anodizing conditions.

A Validated specific Stability-indicating RP-HPLC method for Aripiprazole and its related substances

Image
ABSTRACT : A validated specific stability indicating reversed-phase liquid chromatographic method was developed for the quantitative determination of Aripiprazole and its related substances in bulk samples, pharmaceutical dosage forms in presence of degradation products. Forced degradation studies were performed on bulk sample of Aripiprazole as per ICH prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability indicating power of the method. Significant degradation was observed during basic stress and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from forced degradation studies and the impurity spiked with Aripiprazole. Good resolution between the peaks corresponds to impuritiy-1, degradation products from the analyte were achieved on YMC PACK C18 column using the mobile phase consists a mixture of Sodium dihydrogen Orthophosphate dehydra...
