Taguchi Design for Optimization of Processing Parameters in Green Synthesis of ZnO Nanoparticles

Green synthesis is a simple and eco-friendly method. The aim of this study was to investigate the effect of concentration and temperature factors on the size and morphology of zinc oxide nanoparticles biosynthesized using plant extracts. For this purpose 9 experiments with different conditions were designed and performed using taguchi method.Material and methods:After the plant concentration of 3, 5 and 10% were prepared, zinc nitrate was prepared in 3(1.5.10Mm) concentration and 3 temperatures (40-60-100) were considered for the experiment. The properties of nanoparticles were investigated by UV-spectroscopy, FTIR and FESEM.Result:Designed experiments were performed and the data were given back to the Minitab software. Then, the optimal experiment was determined with a salt concentration of 5mM, 5% extract and temperature of 100. UV-Visible spectrophotometer absorbance peak in 410 nm confirmed the nanoparticles. FESEM showed spherical nanoparticles with smooth surface and an average diameter size of about 12 nm.Conclusion:This study presents using the Taguchi method to obtain optimum conditions in ZnONPs biosynthesis via a leaf extract. Synthesized ZnONPs at the optimal condition had an ideal average diameter size and shape for biological and drug design application. Taguchi method is also a suitable method for optimizing the parameters involved in synthesis and saves costs and time.
