A Review on Properties and Environmental Applications of Graphene and Its Derivative-Based Composites

Catalysts, Journal Year: 2023, Volume and Issue: 13(1), P. 111 - 111

Published: Jan. 4, 2023

Graphene-based materials have gained a lot of scientific interest in the research era modern technology, which can be quite flexible. Graphene has become popular as potential material for manufacture wide range technologies due to its remarkable electrical, mechanical, and optical traits. Due these excellent characteristics, derivatives graphene functionalized various applications including environmental, medical, electronic, defence applications, many more. In this review paper, we discussed different synthesis methods extraction derivatives. The traits such structural, were also discussed. An extensive literature on application graphene-based composites is presented work. We outlined graphene’s realm environmental purification through techniques filtration, adsorption, photocatalysis. Lastly, challenges opportunities advanced reported.

Coal ash for removing toxic metals and phenolic contaminants from wastewater: A brief review

Critical Reviews in Environmental Science and Technology, Journal Year: 2023, Volume and Issue: 53(23), P. 2006 - 2029

Published: May 5, 2023

Over the past few years, population growth, industrial progress and climate change have led to water scarcity. Thus, pollution caused by hazardous soluble insoluble pollutants, such as toxic metals phenolic compounds, has become an important problem that should be dealt with urgently. For instance, new methods been introduced convert low-cost raw materials (i.e. coal fly ash bottom "wastes-to-resource") into suitable for cleaner production achieve sustainability goals in wastewater-containing compounds purification. Obviously, functionalization of enhances ability ash-based entities potential wastewater remediation technologies. Here, we review application ashes, including removal. We also examine their structural properties enhance affinities toward these pollutants aqueous environment. Even though each process its own benefits limitations, appear promising removal using adsorption, membrane filtration, photocatalysis. Overall, study on availability treatment resulted high efficiencies compounds. In future, recycling ashes purification agents further studied advanced processes investigated order purposes.

Synthesis and application of carboxymethyl cellulose-graphene oxide composite for the mitigation of Pb2+ and Cd2+ from aqueous solution

Cleaner Engineering and Technology, Journal Year: 2024, Volume and Issue: 18, P. 100724 - 100724

Published: Jan. 21, 2024

In this work, carboxymethyl cellulose-graphene oxide (CMC-GO) nanocomposite was prepared and used as a low-cost adsorbent to remove Pb2+ Cd2+ from aqueous solution. CMC-GO characterized using various techniques such FTIR, XRD, TGA, zeta potential SEM with EDX. The optimum pH, dose, time, percentage of removal were found 5.0, 1.0 g/L, 60 min, 96.3% for 5.5, 1.5 82.5% Cd2+, respectively at an initial concentration 200 ppm. Freundlich isotherm model pseudo-second order kinetics configured properly experimental data maximum capacity 213.21 mg/g 134.04 ions respectively. positive value enthalpy (ΔH) negative values Gibbs free energy (ΔG) the sorption process indicate endothermic nature spontaneous room temperature. This study revealed that composite could be cost-effective, efficient viable remediation toxic pollution water bodies well wastewater treatment.
