Rapid Green Synthesis of Amalgamated Silver Nanoparticles and its Photocatalytic Activity of Dye Degradation

Organic dye present in the waste water becomes a major threat to the environment. Here we focus our attention to synthesis silver nanoparticles from silver nitrate by Moringa Oleifera flower extract (Green approach). This silver nanoparticle was further amalgamated by mercurous chloride and it was used for dye removal. Here in this present work Methyl orange has been chosen as a dye (20ppm) to analyze the effective dye removal capacity of amalgamated silver nanoparticles in presence of sunlight irradiation. The particles size calculated from UV/Vis absorption study (by the effect of mass approximation) were found to be 3nm and 4nm for amalgamated silver nanoparticles and silver nanoparticles. From the above study conducted it was concluded that the effective dye removal of amalgamated silver nanoparticles (97%) was observed at 52 hrs (or 2.16 days) under photochemical degradation, shifted UV-Vis absorption peak from 520 nm to 232nm.
