Numerical parametric optimization with desirability functions for methylene blue dye removal by sunflower seed pericarp activated carbon
In this study, sunflower seed pericarp activated carbon (SFSPC-AC) was produced from sunflower seed pericarp (SFSPC) using microwave-assisted chemical activation with H3PO4. The SFSPC-AC was characterized using XRD, BET, FTIR, FE-SEM, and EDX techniques. Its effectiveness in removing methylene blue...
