خلاصه مقاله:
In this article, we prepared anionic sorbent using rice husk (RC). Anionic rice husk (ARC) structural characteristics and adsorption properties for nitrate removal from aqueous solution were investigated. The sorption of NO . by batch method is carried out. The optimum conditions of sorption were found to be: a sorbe..nt dose of 0.4g in 100 ml of NO solution, contact time of 90 min, pH= 7. In optimum condition, removal efficiency was 94.3%.. for the NO . The nitrate adsorption process was well described by the pseudo-second-order kinetic model. ..
