Ecofriendly synthesis of silver nanoparticles using Radish microgreens extract and their potential photocatalytic degradation of toxic crystal violet and pyronin Y dyes and antibacterial studies

Life on this planet is seriously threatened by water pollution. Water resources have become contaminated by hazardous contaminants including the effluents of synthetic dyes as a result of industrialization. Therefore, to remove synthetic dyes from industrial effluent, an environment-friendly technique must be proposed. Herein, we are addressing the green synthesis of nano-sized silver particles using radish microgreen extract by wet chemical method. Further, we have characterized them by FT-IR, UV-visible spectra, XRD, and HR-TEM techniques. The synthesized MG-AgNPs exhibit a well-resolved surface plasma resonance (SPR) band at 425 nm. The average size of the particles was calculated to be 16.11 nm. The final MG-AgNPs are also remain as such for two months period. Then, we have applied MG-AgNPs as a photocatalyst for the degradation of toxic crystal violet and pyronin Y dyes. The degradation efficiency of MG-AgNPs for crystal violet and pyronin Y was calculated to be 96.90% and 94.46%, respectively. Finally, we were able to apply MG-AgNPs as photocatalysts for the effective degradation of industrial effluent water. Furthermore, the antibacterial activity of MG-AgNPs was investigated against two bacterial strains, and the zone of inhibition was measured for Staphylococcus aureus and Escherichia coli pathogens.
