Özet:

In recent years, green synthesis has attracted a lot of attention due to its minimal impact on human health and the environment. Fungi, plants and microorganisms, are used in the production of nanoparticles by green synthesis. Nanoparticle synthesis using plants as an alternative to other methods is very important because of its ease of synthesis, low cost and environmental friendliness. Metal oxide nanoparticles produced by this technique are used in many fields. In this study, nanoparticles were synthesized from the dried peels of Diospyros kaki (Persimmon) by green synthesis and their optimum conditions were determined. For this purpose, zinc nanoparticles production experiments were carried out under different pH (2, 6, 8, 10) and temperature (40 °C, 60 °C and 80 °C) conditions and the obtained nanoparticles were characterized. The obtained results of UV-visible spectrophotometry, SEM, Zetasizer and EDAX analyzes were used to determine optimal conditions in nanoparticle synthesis. It has been proven that the appropriate pH value for optimal nanoparticle production is 10 and the reaction temperature is 60 °C. The produced nanoparticle size was determined as 168 nm. The obtained nanoparticles can be used as a suitable material for nanomedicine applications.
