Development of activated carbon from Nerium oleander flower and their rapid adsorption of direct and reactive dyes

The present study investigates the thermally activated carbon derived from Nerium oleander flower which was used an adsorbent. Physicochemical properties of Nerium oleander flower carbon (NOFC) were characterized by scanning electron microscopy, X-ray diffraction, and Fourier transform infrared for the removal of DTB (Direct Turquoise Blue) and RR-HE7B (Reactive red–HE7B) dyes from aqueous solution. Adsorption studies were carried out with different pH, adsorbent dose, contact time, and initial concentration dye solution. Optimum conditions for maximum removal of DTB and RR-HE7B was achieved to be pH 2 for both dyes, adsorbent dose of 100 mg and equilibrium time of 35 and 60 min, respectively, for NOFC. The maximum adsorption capacity of NOFC was found to be 33.33 and 19.60 mg g^?1, respectively, for the removal of dye solution. The mechanism of adsorption was studied by using different kinetic models and isotherms. The results clearly showed that the NOFC adsorption was fitted to pseudo–first-order for DTB and pseudo–second-order for RR-HE7B. Equilibrium data were well fitted with both isotherm models. According to the results, NOFC can effectively remove DTB and RR-HE7B from aqueous solutions.
