Applications of graphene and its derivatives as an adsorbent for heavy metal and dye removal: a systematic and comprehensive overview

“…Moreover, at a pH value greater than 11, a maximum removal efficiency of 99.5% was recorded. However, Chang et al 83 studied the potential to adsorb Fe(II) and Co(II) from aqueous solution using graphene through a batch adsorption technique. The maximum adsorption capacities were found to be 299.3 and 370 mg g À1 for Fe(II) and Co(II), respectively.…”

Electro-deposition of graphene on aluminium open cell metal foams

“…Since it was discovered in 2004, graphene was considered an exceptional material and has been attracting extensive scientific interest from both experimental and theoretical communities [1,2]. Thanks to its particular planar structure, graphene is characterized by unique properties, such as excellent chemical inactivity, high electrical conductivity, high optical transparency, good thermal stability, and extraordinary flexibility [3][4][5][6].…”

Aqueous removal of inorganic and organic contaminants by graphene-based nanoadsorbents: A review

“…These characteristics have attracted substantial scientific interest in graphenes, resulting in many exciting and innovative applications, such as antibacterial papers (Dikin et al, 2007), battery electrodes (Paek et al, 2009), biomedical technologies (Ryoo et al, 2010), conducting polymers (Stankovich et al, 2006), nanoelectronics (Ruoff, 2008), printable inks (Wang et al, 2010), structural composites (Stankovich et al, 2006), supercapacitors (Dikin et al, 2007), and transport barriers (Compton et al, 2010). In recent years, the unique properties of graphenes have led to their use as adsorbents for the removal of both inorganic/heavy metal (Chang et al, 2013;Huang et al, 2011;Leng et al, 2012) and organic (Apul et al, 2013;Bi et al, 2012;Cai and Larese-Casanova, 2016;Liu et al, 2012b;Pei et al, 2013;Raad et al, 2016) contaminants in water and wastewater treatment.…”
