“…RSM offers a cost-effective solution with minimal time requirements, making it an optimal choice for predicting laboratory data. By utilizing RSM, researchers can achieve desired results efficiently, enabling them to make informed decisions confidently [40][41][42][43]. The Response Surface Methodology is a set of statistical techniques used to model and analyze problems in which a response variable is influenced by other explanatory or independent variables.…”

Nitration is a chemical process that introduces a nitro group into a molecule, which modifies properties of organic compounds, impacting their reactivity and physical attributes. In copper mining, elevated nitrate levels present operational difficulties, impacting recovery percentages and leading to the deterioration of organic extractants. Historically, various elements such as intense electrolyte acidity, sunlight exposure, Mn presence, high temperatures, and microbial activity have been linked to this degradation. Over time, numerous methods, including the introduction of additives and the implementation of recirculation approaches, have been developed to address the nitration issue. Mathematical modeling of nitration (like response surface methodology, RSM) based on explanatory variables, such as NO3−, H+, and Potential HNE, has the potential to obtain a better understanding of nitration processes. This study highlights the effectiveness of the TAP Test in assessing the aggressiveness level of nitrates in aqueous solutions and, given the increase in complexity of the minerals in mining sites, it is plausible to anticipate a rise in usage of these tests within hydrometallurgical plants in near future. Using RSM and design of experiments proved robust in examining the nitration phenomenon. Maximum TAP nitration occurred at elevated levels of NO3−, H+, and Potential HNE, with an experimental peak of 17.9%; this contrasts with the theoretical 16.25% from the fitted model (R2≅90%).

“…The F-value and p-value of each model term were used as tools to evaluate each parameter's importance. The magnitude of the F-value was proportional to the effect of this factor on the response surface (Hatami et al, 2023;Latif et al, 2022). Table 3 demonstrated that the yield of the phlorizin-Zn (Ⅱ) complex was significantly influenced (p<0.05) by linear coefficients (X1, X3), cross coefficients (X1X2, X2X3), and quadratic coefficients  …”

Flavonoid metal complexes possess more effective antioxidant properties than flavonoids. However, the preparation of the phlorizin-Zn (Ⅱ) complex and its antioxidant activity has not been reported. In this research, the preparation procedures of the phlorizin-Zn (Ⅱ) complex were enhanced using by single factor test and Response Surface Methodology (RSM). The optimal preparation procedures of the phlorizin-Zn (II) complex were as follows: The time of 4.1 h, the pH of 5.9, the temperature of 48.7°C and the molar ratio (phlorizin: Zn 2+ ) of 1:1. Under these conditions, the predicted preparation yield of phlorizin-Zn (Ⅱ) complex was 79.052%. Additionally, the antioxidant activity of the phlorizin-Zn (Ⅱ) complex was analyzed in this research. 1, 1-Diphenyl-2-Picrylhydrazyl (DPPH), 2, 2'-Azinobis (3-Ethylbenzothiazoline-6-Sulfonic acid) (ABTS), hydroxyl free radical and Ferric ion Reducing Antioxidant Power (FRAP) experiments revealed that phlorizin-Zn (Ⅱ) complex had significant DPPH, ABTS and hydroxyl free radical scavenging abilities and exhibited substantial reducing power in a dose-dependent manner. Moreover, the phlorizin-Zn (Ⅱ) complex displayed stronger in vitro antioxidant capacity compared with phlorizin. The findings demonstrated that the phlorizin-Zn (Ⅱ) complex had great potential in antioxidant applications in the future.
