عنوان انگلیسی Kinetic, Isotherm, and Thermodynamic Studies of Methylene Blue Adsorption over Metal-doped Zeolite Nano-adsorbent
چکیده انگلیسی مقاله In this work, the adsorption of cationic dye by the modified high silica zeolite nano-adsorbent was investigated. The support was prepared hydrothermally and doped by the iron. The morphology, structure, and textural properties of the nano-adsorbents were characterized using XRD, FT-IR, N2 adsorption-desorption, and FE-SEM. The results showed that the nano-adsorbent had a high specific surface area, crystallinity, and pore volume. The maximum adsorption (6.09 mg g-1) was at the pH level of 9.0, 10 mg L-1 of dye concentration, T=25 °C, and 1.0 gL-1 of nano-adsorbent dosage. The kinetic of Methylene blue (MB) adsorption was pseudo-second-order with the high correlation factor (R2=0.99). The MB adsorption was in line with the Langmuir model, as an exothermic and spontaneous process. The results confirmed that the metal-doped high silica ZSM-5 zeolite was an efficient nano-adsorbent for the cationic dye adsorption through wastewater treatment.
