Abstract :In this study production of silver nanoparticles insert ignore into journalissuearticles values(AgNPs); from collard greens were optimized by the design of experiments insert ignore into journalissuearticles values(DOE);. A 24 full factorial design was employed to evaluate the effects on two responses. The optimized values for AgNP production were 1:7 leaf to water, 1:4 extract to AgNO3, 5 molar AgNO3, and a leaf size of <1 mm. For dye removal efficiency, the optimized values were changed to 1:15 of leaf to water and 1:10 of extract to AgNO3, while the other two parameters remained the same. SEM insert ignore into journalissuearticles values(scanning electron microscopy); showed that optimizing the process for dye removal led to smaller AgNP production with increased surface area, resulting in higher absorbency. ANOVA insert ignore into journalissuearticles values(analysis of variance); tables were used to interpret each parameter\`s main and effects on interaction. Additionally, reaction rate kinetics were estimated, and dye removal showed a slightly higher R-square of pseudo second-order than NP production, which fits the pseudo first-order reaction model.
