Carbon-based adsorbents as proficient tools for the removal of heavy metals from aqueous solution: A state of art-review emphasizing recent progress and prospects

Super stable evaporators based on upcycled self-healing adsorbents for wastewater regeneration

“…Rapid industrial development has given rise to a severe energy crises and environmental issues, including water pollution and waste disposal. [1][2][3][4][5][6] Substantial effort has been devoted to waste-to-treasure strategies, thus minimizing energy consumption and environmental impact. [7][8][9][10] The conversion of waste into value-added chemicals such as the utilization of solar energy for wastewater purification is considered as a beneficial processes for resource utilization in an upgraded circular pathway.…”

Recent advances on sustainable removal of emerging contaminants from water by bio-based adsorbents

“…10 Carbon based adsorbents, such as activated carbon, biochar, graphene oxide, and carbon nanotubes, have been widely investigated for diverse pollutant adsorption. 19,20 Biochar (BC), derived from lignocellulosic biomass, has been effective in the removal of CECs from aquatic environments. However, the pure BC's ability to selectively adsorb high Prakash V. Bobde Mr Prakash Bobde is currently working as a Research Scientist in the R & D department of UPES, Dehradun, India, and also pursuing his PhD degree from UPES, Dehradun, India.…”

Synthesis and characterization of ground biochar (GB) reinforced composites for removal of heavy metal from palm oil mill effluent (POME)

“…The search for effective natural-based adsorbent materials has consistently been a vibrant field of study. Several studies have demonstrated the effectiveness of carbonaceous-based composites as adsorbents in removing heavy metals (e.g., cadmium (Cd), lead (Pb), chromium (Cr), mercury (Hg), arsenic (As), zinc (Zn), iron (Fe)) from industrial effluent via adsorption (Gul et al 2021;Kumar et al 2021;Mahesh et al 2022). However, the existing studies still show a lack of information regarding the adsorption of various heavy metals from POME using composites derived from polylactic acid (PLA) and titanium dioxide (TiO2) with ground biochar-adsorbent to overcome the limitation of conventional adsorbents where the interaction between the process parameters has been restricted.…”
