Abstract
In this study, composites of layered double hydroxide (LDH) and activated carbon (AC) derived from Rubus alceifolius biomass were synthesized with varying amounts of AC using the co-precipitation method. The resulting composites were characterized using FTIR, BET, SEM, TEM, EDX, and XPS. The MgAl-AC3 composite exhibited a high BET surface area (568.87 m2 g−1) compared to pure MgAl LDH (73.05 m2 g−1). The adsorption models followed the Redlich-Peterson isotherm and pseudo-second-order kinetics, with thermodynamic analysis confirming a spontaneous, endothermic process. Post-adsorption studies indicated surface adsorption of ciprofloxacin rather than intercalation.
期刊介绍：
Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline.
Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
