Water pollution by industrial effluents has become a major concern that needs prompt action. One of the industrial effluents that have a detrimental impact on human as well as aquatic organisms is dye particles. In this experiment, a comparative study had been performed for the removal of Methylene Blue and Malachite Green dye by adsorption using a novel adsorbent. The adsorbent is obtained by Green synthesis of silver nanocomposites using Neem leaf extract (Azadirachta indica) and Basil leaf extract (Ocimum sanctum). Both the nanocomposites were characterized by a change in colour, spectroscopic analysis, X-Ray Diffraction Analysis (XRD), Scanning Electron Microscopic Analysis (SEM), Fourier-Transform Infrared Spectroscopic Analysis (FTIR) and Transmission Electron Microscopic Analysis (TEM). Experiments were also carried out varying the operating parameters (adsorbent dose, temperature, shaker speed, time, pH and concentration) in Methylene Blue and Malachite Green dye solutions using both adsorbents and the results were tallied. Adsorption isotherms, thermodynamic study and kinetics were also evaluated. The silver nanocomposite from Basil leaf provided 98% removal of Methylene Blue dye and 95% of Malachite Green dye which was relatively higher than Neem leaf composite.
