Statistical comparison of silver nanoparticles' properties synthesized with tannic acid and ascorbic acid

Silver nanoparticles have been one of the most studied nanomaterials in recent years due to their antibacterial properties and important mechanical properties. Reducing agents have an important place in the synthesis of silver nanoparticles. Although hydrazine and sodium borohydride are among the most preferred reducers, they are not preferred because they are both carcinogenic and toxic. Recently, green reducers have been preferred to toxic chemicals such as sodium borohydride, especially in the reduction step. In particular, the success of glucose and ascorbic acid in the synthesis of nano-sized silver nanoparticles is promising for a more environmentally friendly approach. In this study, in contrast to literature studies, the properties and efficacy of silver nanoparticles obtained with tannic acid and ascorbic acid, in particular particle size distribution, will be statistically compared. This study proposed a systematically design of expert method for the synthesis of silver nanoparticle (AgNPs) and characterized with the use of Taguchi L4 experimental design. The experiments were carried out using 23 orthogonal arrays and main and interaction effects are prepared. Silver nitrate is used as a raw material and soluble starch as a coating agent. Tannic acid and ascorbic acid will be used as reducing agents. Synthesized nanoparticles will be characterized using FTIR, zetasizer and ultraviolet-visible (UV-Vis) spectroscopy. The average size distribution of silver nanoparticles and product efficiency will be statistically compared by paired-t analysis and statistical comparison of the properties of silver nanoparticles obtained with tannic acid and ascorbic acid. The glucose/AgNO3 and ascorbic/AgNO3 molar ratios were shown to have the greatest influence on AgNPs particle size dispersion. The findings demonstrate that the lowest variances AgNPs are produced at the greatest Ascorbic/AgNO3 molar ratios. As a result, it can be said that the higher-quality AgNPs production process is possible by adjusting Ascorbic/AgNO3 molar ratio.
