Abstract

Bentonite is a clay which has high surface area and makes it a good option for the placement of metal oxide nanoparticles, such as Zinc oxide, thereby forming a Nanocomposite. In the recent years, various applications of this kind of Nanocomposites have been investigated by researchers in water and wastewater treatment. Accordingly, in this research, the Bentonite was powdered by ball mills and then, ZnO/Bentonite Nanocomposite was prepared by ultrasound irradiation and gel degradation method with starch. The Nanocomposite was identified by XRD, FTIR, SEM and EDX techniques, and the efficiency of the sample was studied for removing of nitrate ions from water. The results showed that environmental factors such as pH, contact time, adsorbent amount, and nitrate concentration were effective in removal percentage. Optimal removing percentage of the nitrate solution with 30 mg/l was achieved by 0. 6 g of Nanocomposite which could remove 70% of the nitrate from solution.
