Continuous modifications of Layered Double Hydroxides (LDH) materials are essential to enhance their structural stability and improve capacity for pollutant adsorption, addressing the need more effective remediation strategies in environmental applications. This research study has proposed preparation CuAl-LDH supported filamentous macroalgae Spirogyra sp. (CuAl-LDH/SA) via coprecipitation hydrothermal methods. The prepared CuAl-LDH/SA composites were investigated adsorption direct yellow 12 (DY) remazol red (RR) dyes batch mode experiments. structure morphology identified by X-ray Diffraction (XRD), Fourier Transform Infra Red (FT-IR), (Brunauer-Emmett-Teller) BET surface area, Thermogravimetry / Differential Thermal Analyzer (TG/DTA), Scanning Electron Microscope (SEM). For process, effects initial pH, contact time, concentration, temperature, selectivity, adsorbent regeneration, as well kinetics, isotherms, thermodynamics studied. selectivity test resulted RR dye being selective compared DY. maximum capacities 72.464 mg/g (pH = 2, 150 min, 303 K). can be regenerated 4 cycles with a percent removal 29.32%. process followed intraparticle diffusion kinetics model Langmuir isotherm. Thermodynamic studies showed that using was endothermic spontaneous. results this indicate composite material shows potential anionic from aqueous solutions.
