Abstract:
In last decades, the pollution of ground and surface water with nitrate has been observed in many countries.1 Drinking water, high in nitrate condensation, can cause health problems and increase the rates of cancer.2 Nitrate removal from environmental sources such as surface water and ground water is so necessary for prohibiting such issues.3 In this work, we used of ion-exchange technology for removal of nitrate. At the first, a novel nanocomposite adsorbent was synthesized based on modified graphene oxide (Scheme1). The obtained adsorbent was investigated by FESEM, TGA and FT-IR spectra. The effects of solution pH, contact time, initial concentration of nitrate, adsorbent dosage, temperature and competing anions on nitrate adsorption was investigated. The maximum nitrate removal efficiency was achieved 92%. Antimicrobial and antifungal activity of adsorbent was carried out by disc diffusion method in vitro. Also, isotherm models, kinetic adsorption mechanism and thermodynamic parameters were investigated.
