Removal of hexavalent chromium from contaminated synthetic groundwater via functionalized carbon nanomaterials modified with zinc and potassium.

ABSTRACT: Chromium has been shown to be a significant contributor to water pollution, leading to cancer. This study aimed to investigate the potential of various functionalized carbon nanomaterials for removing Cr(VI) from synthetic groundwater. Functionalized carbon nanomaterials with layered and tube-like structures were designed on the basis of thermal methods (KOH-activated micrographite sheets) and impregnation methods by anchoring K and Zn on carbon nanotubes (CNTs), respectively, for the removal of Cr(VI) from contaminated synthetic groundwater. Several experimental parameters, including the concentration of the solution, pH, adsorbent dosage, and duration of contact, were systematically varied in a series of batch experiments. The optimal conditions were determined to be a 30 mg/20 mL adsorb
