In the current research, the removal efficiency of the toxic synthetic dye Brilliant Blue FCF-E133 from aqueous solutions was studied by synthesizing Mg–Al layered double hydroxide nanoparticles. These nanoparticles are synthesized by the coprecipitation method and analyzed by FT-IR, SEM, EDS and XRD results. Batch mode adsorption experiments are carried out to understand the results in terms of the effect of pH, temperature, concentration and adsorbent dosage. Finally, the removal efficiency is at an optimized pH of 9. Thermodynamic and kinetic studies are carried out to understand the adsorption mechanisms. Moreover, density functional theory simulation results are given, which are carried out by the B3LYP/DND. From the results and simulation findings, it can be concluded that the synthesized Mg–Al hydroxide particles are an efficient and economic adsorbent that can be employed in the removal of organic dye from wastewater.
