PAR-intercalated Mg/Al layered double hydroxide for efficient adsorption of acid fuchsin: experimental study and molecular docking insights.

ABSTRACT: This study systematically investigated the adsorptive removal of acid fuchsin (AF), an anionic dye, from aqueous solutions using a 4-(2-pyridylazo)resorcinol-intercalated magnesium/aluminum layered double hydroxide (PAR-Mg/Al LDH). The composite was successfully synthesized and characterized by FTIR, XRD, SEM, EDX, and XPS. Batch adsorption experiments demonstrated that PAR intercalation significantly enhanced the adsorption performance compared to pristine Mg/Al LDH. Key parameters influencing the adsorption process, including contact time, initial dye concentration, pH, and temperature, were systematically optimized. The adsorption isotherm data were best described by the Langmuir model, indicating monolayer adsorption with a high maximum capacity of 568.18 mg g^-1. Kinetic stu
