Grafen oksit örnekleriyle borik asit giderimininoptimizasyonu

The world's greatest reserves of boron are found in Türkiye. Boron compounds, such as boric acid, borax, boroxide, are generated in Türkiye by processing boron ores. Environmental issues come from the formation of boron waste during production operations, as this waste cannot be evaluated. This work aims to characterize the optimization of adsorption of synthetically generated boric acid solutions using graphene oxide samples by the Taguchi method. The study used the L9 (34) experimental design, which has 4 factors and 3 levels. The factors that were chosen were the pH of the solution, the method used to make graphene oxide, the amount of graphene oxide that was used, and the concentration of boric acid. The Staudenmaier, Staudenmaier-Hummers, and Hummers techniques were chosen for the production of graphene oxide at pH levels of 3.5, 7, and 10. The amounts of graphene oxide used were 1g, 2g, and 3g. The experiments were conducted using the L9 (34) experimental design, model. Raman spectroscopy was used to determine the D/G peak ratio in graphene oxide samples. SEM+EDS analysis was conducted to measure the C/O ratio. BET analysis was employed to measure the surface area. The zeta sizer was used to analyze the zeta potential and particle size distribution. Finally, FTIR was used for structural characterization. It was measured to see how much boric acid was left in the fluid and how much boric acid was kept per gram of graphene oxide. The Taguchi method was used to assess the adsorption of boric acid on graphene oxide samples of the criterions numerical results. Optimum points were obtained for each criterion. Due to variations in the characteristics of graphene oxide, distinct patterns have been discovered at the places that yield the best results for each criterion. When evaluating the adsorbed boric ii acid per gram graphene oxide, it was noted that the retention of boric acid per gram of graphene oxide increased with higher pH levels and greater boron concentration in the solution. Additionally, the quantity of graphene oxide utilized dropped as the amount increased. The Staudenmeair method has demonstrated greater efficacy in adsorbing boric acid than the Hummers method. It's possible that graphene oxide can be used on its own for boric acid binding once the Taguchi optimization results of the L9(34) experimental design are looked at. Furthermore, boric acid adsorption has been shown to improve the criteria properties of graphene oxide, according to the optimization results. These findings indicate that graphene oxide is a useful material for eliminating boron industrial process waste.
