| Abstract | ||||
| Silica/corncob nanocomposite was prepared for remove of methylene blue. Fourier transform infrared (FTIR) spectrophotometry, X-ray diffraction (XRD), Scanning electron microscopy (SEM), dispersive energy x-ray spectrometer (EDX), High-resolution transmission electron microscopy (HR-TEM), and Zeta potential measurements were performed to reveal functionality, crystal structure, morphology, and point of zero charge of the synthesized sorbents. The effect of contact time, initial dye concentration, pH and sorbent dose were evaluated to study the removal efficiency and the adsorption capacity for silica/corncob nanocomposite. The equilibrium concentration of dye was measured by spectrophotometer. Adsorption isotherms and kinetics were also evaluated and reported. The removal efficiency of silica/corncob nanocomposite was (98%). | ||||
