Photostablity of bis-(2-nitrobenzalidene)‎ benzidineb by different types of radiation

Abstract EN

The stability of synthesized Schiff base [Bis-(2-chlorobenzalidene) benzidine] have been studied under different types of light (UV , Visible and sunlight) kinetic study of photolysis was done in DMF solvent by monitoring the concentration of Schiff base, using UV-Vis spectroscopy .

The High Performance Liquid Chromatography analytical technique coupled with UV-visible spectrophotometer used to detect the intermediate compounds formed in the photolysis it was found that the photolysis process exhibited pseudo-first-order kinetics.

The results show the photolysis rate constants in the process using UV light is higher than that using visible or sunlight radiation
