Biosynthesis of silver nanoparticles from the mangrove avicennia marina and its applications

In recent years, green synthesis of silver nanoparticles (AgNPs) has gained much interest from chemists and researchers and also increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, chemistry, energy, and medicine. The present investigation attempted on bio-synthesis of sliver nano particles. These nano particles were biologically synthesis by using mangrove plant A. marina leaf extract. Screening of Mangrove for nano particles synthesis tested as evident by the Visual observation and UV-VIS spectroscopic data after 24 hrs of reaction. The peak of colour intensity was observed at 24 hrs of incubation. There was no significance change of colour intensity beyond 24 hrs. The synthesis of sliver nano particles was confirmed by the brown colour with peak of absorption surface at 420 nano meter. The nano particles were spherical with size of 10 to 30 nano meter and with good stability. The Nano particles were successfully deposited on the poly urethane foam filter and tested for water purification. The chemical characteristics of control and nanoparticle treated samples was clear, colourless and odourless. TDS under permissible limit. After treatment pH of the sample becomes neutral. Micro as well as Macro nutrient of the samples under acceptable limit.
