batch adsorption

The contamination of water bodies with harmful pollutants considers an aggravating global problem. The current research focuses on a developing efficient adsorbed for removing nitrate ions from aqueous solutions. The study proposed modified chitosan-zeolite composite beads to enhance the performance of the adsorption process. The zeolite was used to increase the surface area, and Zirconium was loaded on the beads to promote the selectivity for nitrate anions.

The study's objective is to produce and evaluate Nano Graphene Oxide (GO) before using it for batch adsorption to remove heavy metals (vanadium V⁺⁵, nickel Ni⁺², and cadmium Cd⁺²) ions from aqueous solutions polluted with these metals, which were used to imitate the contaminating elements found in the liquid industrial wastewater of the Doura oil refinery in Baghdad, Iraq. This study used a modified Hummers method to synthesize.
