Carbon nanotubes and graphene-based materials for adsorptive removal of metal ions – A review on surface functionalization and related adsorption mechanism

A nano CoFe2O4 entangled CMC/psyllium/RGO (CPRHG/CF)-based hydrogel composite for the adsorption & photocatalytic removal of pharmaceutical effluent: tramadol

“…26 In recent times, carbon materials such as graphene oxide (GO) and reduced graphene oxide (RGO) have found applications in various fields. [27][28][29] This is attributed to their appealing properties, including the presence of an adventitious sp 2 hybrid carbon network that confers high surface area, exceptional thermal and mechanical properties, and electrical conductivity. 30,31 The incorporation of RGO into the polymeric structure is aimed at providing additional strength and stability to the polymeric hydrogel.…”

Unveiling the contemporary progress of graphene-based nanomaterials with a particular focus on the removal of contaminants from water: a comprehensive review

“…Given that aquifers worldwide are being depleted as a result of various factors, including surface water contamination and saltwater intrusion, now is the ideal time to address water-related issues. Improving purification technology can lessen issues related to energy, water scarcity, health, and climate change ( Krishna et al, 2023 ). Reusing wastewater (WW) can result in a significant reduction in the amount of potable water used, but doing so needs the development of dependable, efficient, and affordable materials and techniques.…”

Removal of Bisphenol A from Water by Single-Walled Carbon Nanotubes Loaded with Iron Oxide Nanoparticles

“…With their exceptional adsorption efficacy, various carbon materials [11], such as graphene oxide (GO), activated carbon (AC), and carbon nanotubes (CNTs) [12][13][14][15], have been increasingly adopted as preferred adsorbents for the eradication of contaminants from aquatic environments. Among them, CNTs [16], as a new adsorbent material, have been used in many studies [17] to adsorb pollutants in water owing to their extensive surface area and plentiful reactive sites. Evidence confirms that CNTs possess a strong capacity to adsorb phenols, heavy metals, and natural organic compounds effectively [18].…”
