The purpose of this research is to use a simple method to prepare magnetic modified corncobs (MCBs) with good adsorption performances for Congo Red (CR). The adsorption was analyzed by Fourier transform infrared spectroscopy and x-ray diffraction. The maximal adsorption capacity of the MCB for CR was 198.2 mg/g and about 5.5-fold for unmodified corncob. Potassium ion was more positive effect onto adsorption than sodium ion. The dye uptake process obeyed the pseudo-second-order kinetic expression. The best-fitted data were obtained with the Langmuir model. The as-prepared magnetic modified sorbent had a potential in the dyeing industry wastewater treatment. GRAPHICAL ABSTRACT
