PG - 3618-3622 LID - 10.1002/jemt.24214 [doi] AB - Ficus religiosa bark extract was chosen as a reducing agent to fabricate biogenic silver nanoparticles (AgNPs), which were used to treat chromium in synthetic wastewater. The AgNPs formed were characterized using ultraviolet-visible absorption spectroscopy (UV-vis), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The results of AgNPs characterization showed that the UV-vis spectrophotometer gave an absorbance peak for AgNPs synthesized from bark extract at 448 nm. The peaks in the XRD pattern of AgNPs synthesized from the bark extract of Ficus religiosa are associated with that of the face-centered-cubic form of metallic silver. The SEM analysis showed clear spherical morphology of AgNPs. These synthesized AgNPs were applied for the removal of chromium from synthetic wastewater. It was seen from the treatment results that above 74.8% removal efficiency was achieved. HIGHLIGHTS: Green synthesis of nanoparticles using plant extracts and their successful application in various fields has been previously studied by various researchers. Ficus religiosa bark extract was used for the synthesis of silver nanoparticles, which after characterization using ultraviolet-visible absorption spectroscopy, scanning electron microscopy, and X-ray diffraction were used to treat chromium in synthetic wastewater prepared in lab. The use of silver nanoparticles for the treatment of heavy metals in wastewater can be considered a good replacement option for the conventional treatment techniques.
