Rapid Biosynthesis of Silver Nanoparticles by Exploiting the Reducing Potential of Trapa bispinosa Peel Extract

الملخص EN

Present work reports exceptionally high reducing capacity of Trapa bispinosa to synthesize monodispersed silver nanoparticles (SNPs) within 120 seconds at 30°C which is the shortest tenure reported for SNP synthesis using plants.

Moreover, we also instigated impact of different pH values on fabrication of SNPs using visible spectroscopy with respect to time.

Percentage conversion of Ag+ ions into Ag° was calculated using ICP-AES analysis and was found to be 97% at pH = 7.

To investigate the reduction of Ag+ ions to SNPs, cyclic voltammetry (CV) and open circuit potential (OCP) using 0.1 M KNO3 were performed.

There was prompt reduction in cathodic and anodic currents after addition of the peel extract which indicates the reducing power of T.

bispinosa peel.

Stability of the SNPs was studied using flocculation parameter (FP) which was found to be least at all the pH values.

FP was found to be indirectly proportional to stability of the nanoparticles.
