Abstract
In this report, RuO2@ZnO nanostructure was synthesized, characterized, and employed for Congo Red (CR) dye removal from the aquatic phase. The influence of sorption factors contact time, pH, and concentration, was examined. The results indicates the formation of RuO2@ZnO nanostructure with surface area of 21 m2 g-1 and pore size of 23.5 nm. . The highest amount of Congo red adsorbed by RuO2@ZnO nanostructure was 102.42 mg/g. Excellent obedience was found between the equilibrium data and the Langmuir model (R2 > 0.9338), whereas the adsorption kinetics was consistent with the pseudo-second-order equation (R2 > 0.9999).
