Vandana Sukhadia*, Rashmi Sharma and Asha Meena   Pages 1 - 14 ( 14 )


Aims: The aim of this research work is to synthesise, study and analyse photocatalytic degradation, kinetics.

Background: Copper(II)mustard thio urea complex has been synthesized and characterized through FT-IR, NMR, ESR studies.

Objective: Photocatalytic degradation of copper(II) mustard thio urea complex was studied in the presence of ZnO as catalyst in the solution form using non polar solvent benzene and polar solvent methanol with different compositions. Antibacterial activities of copper(II) complex has also been studied against Staphylicoccus aureus.

Method: O.D. was measured after different time intervals spectrophotometrically to measure the degradation of complex. Mueller-Hinton agar medium was used for antimicrobial activity of synthesised compound at different concentrations by disk/ well diffusion susceptibility testing.

Result: Plot of 2+log O.D. (absorbance ) versus time was plotted and found linear. The heterogeneous photocatalysis followed pseudo-first-order reaction kinetics .The present study suggests that CMT complex shows antibacterial activity at different concentrations.

Conclusion: The rate of photocatalytic degradation of CMT complex was studied and analyzed. It has been found that rate of degradation varies with different parameters like concentration of complex, amount of catalyst, light intensity, solvent polarity etc. CMT complex derived from natural mustard oil has been shown an inhibitory effect on the growth of S. aureuswhich may causes skin disease.
