Abstract

Long-term drinking of Nitrate-contaminated water poses a serious risk to human health. The present study explores the possibility of enhancing the adsorption capacity of Graphene oxide via Activation with hydrochloric acid for Nitrate removal from aqueous solutions. Experiments were performed in a batch reactor in which such major factors as pH, reaction time, and concentrations of both Graphene oxide (GO) and activated Graphene oxide (AGO) were used as variables. Nitrate removal efficiency was investigated using the One-Way ANOVA statistical test and SPSS-16 software. The chemical composition and solid structure of the synthesized AGO were analyzed using FE-SEM coupled with energy dispersive spectrometry (EDS). The micropore volumes of the samples were determined using the BET and BJH. The predominant composition (52%) of the synthesized AGO was C and its mean pore diameter was 26. 896 nm. The maximum adsorption capacity of AGO was estimated at 3333. 33 mg/g. Based on the results, the AGO nano-structure may be recomended as a new means for Nitrate removal from aqueous solutions.
