Comparative study of photo catalytic activity of Tinospora Cordifolia derived nanoparticles for degradation of indigo carmine

Plant-mediated synthesis of nanoparticles has emerged as an important field in synthesis of nanoparticles (NPs) as fewer chemicals are being used, method is cost-effective and also fulfils principles of green chemistry. Due to the rapid growth of industries in recent times, there has been an increase in concentration of dyes in water, which causes problems and affects human and animal's health. Moreover, nanoparticles has emerged as an effective solution for dye degradation due to their effective catalytic activity. In the current work, we carried out a comparative study on Tinospora Cordifolia, derived oxide nanoparticles for degrading Indigo Carmine. The characterization of formed particles have been done by techniques like XRD, SEM, FTIR and EDX. The effectiveness of the synthesized nanoparticles as photo catalyst in removing indigo carmine was assessed by emphasizing on important aspects such as amount of catalyst, concentration of dye, and the pH. The results showed SnO2 nanoparticles exhibited superior degrading activity compared to CuO. The optimal dose for SnO2 NPs was 0.25 g/L, while for CuO, it was 0.50 g/L. When pH was altered, it was observed that acidic environment exhibited superior breakdown ability. The optimal degradation capability was observed at dye concentration of 40 parts per million (ppm).
