“…In addition, they included an experiment on adsorption of 2,4-dichloro-phenoxy acetic acid. It was shown in this study that AC was able to remove 175.4 mg/g of pesticides from aqueous solution (Salman and Hussein, 2014). Olive kernel, corn cob, soya stalks, and rapeseed stalks were physically activated to produce ACs for the removal of bromopropylate.…”

“…Due to their mutagenicity and carcinogenicity, they are considered as threats to the aquatic environment and human health, and their maximum concentrations in water are set at certain levels. The permissible concentrations in tap water and potable water are 0.05 mg/L, 0.09 mg/L and 0.1 mg/L for bentazon, carbofuran and 2,4-dichloro-phenoxyacetic acid, respectively (Salman and Hussein, 2014). Based on these results, adsorption as one of the most effective separation techniques being used for the removal of pesticides from water resources (Ahmed, 2016a).…”

Without pure water, it is impossible to survive for any living beings. The ratio of freshwater on our planet is very poor and the demand is increasing with time for the growing population. Furthermore, water is being contaminated by industrial and agricultural activities, pharmaceuticals, technocratic civilization, pesticides, garments, global changes etc. In addition to this, environmental pollution and global warming are swelling due to the greenhouse and harmful gases generated from the dumping and burning of fossil fuel. Addressing these problems, it is necessary to find out the cost-effective and environmental friendly processes to purify the contaminated water and air. Activated carbons (ACs) are one of the best solutions for removing the pollutants from aqueous and atmosphere as it is the carbonaceous materials with a high degree of porosity, well-developed surface area, and distinguished functional groups which are required for elimination of contaminants. The preparations of activated carbon are easy and safe processes, mainly from the pyrolysis or gasification of biomass with heat and/or chemicals. The recycling and regeneration of activated carbon after use are also essential for resource maintenance and environmental safety. Thus, AC can protect the ecosystem in a double direction by purifying the water and air from the pollutants.

“…Most studies from the literature have reported that the adsorption of pesticides on carbonaceous materials was well represented by Freundlich model. [16,20] Some researchers have shown that adsorbents prepared from thermal treatments like pyrolysis exhibited a more diverse range of isotherms indicating the heterogeneous nature of adsorption the BCs in covered crucibles at 450 °C for 1 h. Ash content was measured by heating samples in an open top crucible at 750 °C for 1 h. Finally, the weight percentage of fixed carbon was calculated from ash, volatile matter and moisture contents. The elemental composition (C, H, n, S and O) was determined using dry combustion method (model Vario MAX Cn, elementar, Hanau, Germany).…”

Biochars showed a potential as adsorbents for organic contaminants, however, have not been tested for carbofuran, which has been detected frequently in water. This study provides evidences for the use of infused tea residue derived biochar for carbofuran removal. Biochars were produced at 300, 500 and 700 °C by slow pyrolysis and were characterized by proximate and ultimate analysis, FT-IR, SEM, BET and pore size distribution. Pyrolysis temperature showed a pronounced effect on biochar properties. The maximum carbofuran removal was achieved at pH 5. Freundlich and Temkin models best fit the equilibrium data. Biochars produced at 700 °C showed the highest sorption intensity. The adsorption process was likely to be a favorable chemisorption process with electrostatic interactions between carbofuran molecules and biochar surface. Acid-base interactions, electrophilic addition reactions and amide bond formations are the possible mechanisms of carbofuran adsorption. Overall, biochars prepared from tea waste can be utilized as effective adsorbents for removal of aqueous carbofuran.

“…Their optimum water concentrations are set at certain thresholds because of their carcinogenicity and mutagenicity, which are deliberate dangers to the natural ecosystem and human health. For bentazon, carbofuran, and 2,4-Dichloro-phenoxyacetic acid, the maximum allowable concentrations in water are 0.05 mg/L, 0.09 mg/L, and 0.1 mg/L, respectively [186]. In light of this, one of the most powerful separation methods for removing chemicals from water supplies is adsorption [69].…”

Advanced Applications of Carbonaceous Materials in Sustainable Water Treatment, Energy Storage, and CO2 Capture: A Comprehensive Review

et al. 2023

The demand for energy has increased tremendously around the whole world due to rapid urbanization and booming industrialization. Energy is the major key to achieving an improved social life, but energy production and utilization processes are the main contributors to environmental pollution and greenhouse gas emissions. Mitigation of the energy crisis and reduction in pollution (water and air) difficulties are the leading research topics nowadays. Carbonaceous materials offer some of the best solutions to minimize these problems in an easy and effective way. It is also advantageous that the sources of carbon-based materials are economical, the synthesis processes are comfortable, and the applications are environmentally friendly. Among carbonaceous materials, activated carbons, graphene, and carbon nanotubes have shown outstanding performance in mitigating the energy crisis and environmental pollution. These three carbonaceous materials exhibit unique adsorption properties for energy storage, water purification, and gas cleansing due to their outstanding electrical conductivity, large specific surface areas, and strong mechanical strength. This paper reviews the synthesis methods for activated carbons, carbon nanotubes, and graphene and their significant applications in energy storage, water treatment, and carbon dioxide gas capture to improve environmental sustainability.
