چکیده
In this study, activated carbon was prepared from an abundant Egyptian agricultural waste material (Corn Cob) through microwaves assisted activation. The effect of using two different activating agents (potassium hydroxide and ammonium sulfate), with various ratios impregnation (RI) (0.25, 0.75, 1.25), on the adsorption capacities were investigated. characterized Raman spectroscopy, scanning electron microscopy (SEM), nitrogen adsorption–desorption. efficiency as adsorbent investigated by studying removal methylene blue (MB) organic pollutants aqueous solutions. Adsorption experiments for are described in detail. parameters affecting process such contact time, initial dye concentration discussed detail well. isotherm fits well Langmuir model maximum capacity qmax = 333 mg/g. kinetics data fitted pseudo-second-order model. Accordingly, can be utilized remediation wastewater high superior stability.
