Abstract
Background and aim: Silver nanoparticles can be synthesized by using a variety of methods. Green synthesis of silver nanoparticles makes use of plant extracts or constituents to synthesize silver nanoparticles. Onopordum acanthium is used traditionally for the treatment of many diseases and therefore can be a good source for nanoparticles synthesis. The aim of this study was to synthesize AgCl nanoparticles using Onopordum acanthium extract. Materials and methods: After drying the plant flower in the shade, it was crushed to powder. The plant powder was placed in 50% alcohol for 48 hours. The solution was passed through filter paper. The obtained solution was dried with freeze-drying, and the dried and frozen extract of the plant was obtained. Potassium chloride solution was added to the aqueous solution of plant extract. The solution was added to silver nitrate and shaken for 24 hours and as a result, AgCl nanoparticles were synthesized in the solution. Results: The particle size and surface morphology were investigated by X-ray diffraction (XRD) and field emission scanning electron microscopy. The results showed that the AgCl nanoparticles were agglomerated and had a spherical shape with an average size of 13 nm in diameter. The XRD spectrum confirmed the identity of synthesized nanoparticles. Conclusion: Our findings indicated that AgCl nanoparticles are successfully synthesized by Onopordum acanthium extract.
