“…The adsorption capacity of the as‐prepared carbon‐based adsorbents toward HMIs usually shows a strong dependence on the pH of the solution. For example, AC derived from rice husks showed an increase in adsorption capacity toward Pb 2+ from 125 to 238.3 mg g −1 when the solution pH increased from 2 to 5 . The influence of pH value on the adsorption capacity can be explained by the ion‐exchange process between H 3 O + and Pb 2+ .…”

Carbon-based functional materials hold the key for solving global challenges in the areas of water scarcity and the energy crisis. Although carbon nanotubes (CNTs) and graphene have shown promising results in various fields of application, their high preparation cost and low production yield still dramatically hinder their wide practical applications. Therefore, there is an urgent call for preparing carbon-based functional materials from low-cost, abundant, and sustainable sources. Recent innovative strategies have been developed to convert various waste materials into valuable carbon-based functional materials. These waste-derived carbon-based functional materials have shown great potential in many applications, especially as sorbents for water remediation and electrodes for energy storage. Here, the research progress in the preparation of waste-derived carbon-based functional materials is summarized, along with their applications in water remediation and energy storage; challenges and future research directions in this emerging research field are also discussed.

“…In the present study, graphene oxide (GO) was utilized as the adsorbent to remove the Pb(II), as the GO contains various kinds of nitrogen or oxygen‐containing functional groups, which can take part in the formation of the covalent bonds with the metal ions. According to the previous literature, the batch processes of the Pb(II) adsorption are advantageous concerning its safe and easy operation, but it demands higher energy and a more extended time 5‐16 . Compared to the batch process, the continuous process is cost‐effective and efficient.…”

The present study depicts the hydrodynamics and the mixing characteristics in a millichannel‐based serpentine fixed‐bed device to attain the particular demands of the miniature adsorption devices' fabrication. Residence time distribution analyses were accomplished to analyze the velocity distribution inside the packed bed geometry. The effects of operating variables on the system hydrodynamics and mixing and their impact on the lead adsorption characteristics were enunciated. New correlations were proposed for the frictional resistance and axial dispersion of the fluid. The parametric effects on the lead ions [Pb(II)] adsorption were studied in the same millichannel geometry packed with the graphene oxide coated glass beads. The kinetics of the adsorptive removal process is assessed by the Thomas model and the Yoon–Nelson model. The regeneration study of the said millichannel‐based fixed‐bed device was also executed.
