Abstract
In this manuscript we have reported an easy, eco-friendly and green chemical process for the synthesis of silver nanoparticles (AgNPs) by taking silver nitrate as the metal precursor and aqueous extract of fruits of phyllanthus acidus: phyllanthus family as both the reducing agent as well as capping agent. The formation of AgNPs has been investigated using UV–Vis spectroscopy where gradual generation of an intense surface plasmon resonance band at 425 nm clearly indicates the formation of silver nanoparticles. The optimum condition for the formation of AgNPs has also been established using UV–Vis spectroscopy. AgNPs have further been characterized by powder X-ray diffraction method, Fourier transform infrared spectroscopy, Scanning Electron Microscope and Transmission Electron Microscope. Interestingly, the synthesized AgNPs is used successfully for the detection of environmentally hazardous mercury ions in aqueous solution by colorimetric method. Furthermore, it has been found that the silver nanoparticles show reversible response towards mercury ion. Again, these AgNPs shows observable antibacterial activity against A. hydrophila. © 2019
