Biogenic silver nanoparticles can be an effective and efficient water purification agents of future

The present work was carried out to green synthesis of silver nanoparticles by using fresh aqueous tuber extract of <i>Jatropha heynei</i>. The Jt-AgNPs are characterized by different spectroscopic techniques, the surface plasmon resonance of Jt-AgNPs was observed at 420 nm. The FTIR analysis revealed that various functional groups of tuber extract are responsible for the reduction. The average particle size of Jt-AgNPs was detected to be around 12.4 nm ± 1 nm and the zeta potential of Jt-AgNPs was around −13 mV, the negative charge indicates stability and dispersion of the nanoparticles. The elemental silver in Jt-AgNPs was found by EDAX and is around 81.96%. The XRD analysis revealed that the Jt-AgNPs are crystalline in nature. The antibacterial activity on both Gram − ve and Gram + ve bacteria showed excellent activity. The antibacterial potential of Jt-AgNPs resulted in promising inhibitory activity against total coli forms in the drinking water. Finally, we can conclude that Jt-AgNPs may probably be used as water purification agents in the future.
