Green Synthesis, Characterization and Stabilization of Nanoparticles Silver with Thuja Orientalis Extract
Green synthesis represents an eco-friendly alternative to the environment by minimizing the use of chemical reagents and reduces temperature and pressure conditions. Thuja orientalis has a wide medical use because it contains a large amount of compounds derived and was decided to use for the synthesis of nanoparticles. Leaf extract was obtained and characterized by Infrared Spectroscopy Fourier Transform (FTIR) observed carboxyl groups (-C=O), hydroxyl (-OH) and aromatic amines (-NH), then proceeded to the synthesis of nanoparticles, using AgNO3 as precursor at a concentration of 15 mg L-1, obtaining AgNPs was verified by observing the Ultraviolet-visible Spectroscopy (UV-Visible) absorbance characteristic plasmon between 410-420 nm which reveals the reduction of silver ions (Ag +) into metallic silver (Ag0), the aqueous solution was characterized by scanning electron microscopy (SEM) nanometric sizes observed. The particles obtained were stable for 4 months in aqueous solution, where the characteristic plasmon absorbance was observed by UV-visible spectroscopy for this time.
