Studies on the Adsorption of Methylene Blue Dye from Aqueous Solution onto Low-Cost Tartaric Acid Treated Bagasse

The capacity of tartaric acid (TA) treated bagasse for adsorption of methylene blue (MB) dye from aqueous solution was studied in batch experiments. The effect of relevant parameters such as function of pH, adsorbent dosage, contact time, and initial MB dye concentration was evaluated. The adsorbent was characterized using Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). Experimental data were analyzed in terms of pseudo-first order, and pseudo second order. The results showed that the adsorption process of MB dye followed well pseudo-second order kinetics. The adsorption data of MB dye at 300, 303, 313, 323, 333 K are corresponded to Langmuir, and Freundlich isotherms. The adsorption process followed the Langmuir isotherm as well as Freundlich isotherm.
