Lead and copper removal from aqueous solutions using carbon foam derived from phenol resin

Removal of Heavy Metals and Metalloids from Water Using Drinking Water Treatment Residuals as Adsorbents: A Review

“…Adsorption seems to be one of the best-suited methods, due to its high efficiency, low-cost, and ease of operation. Various adsorbents, such as carbon foam [30], activated carbon [31], zeolite [32], clay minerals [33,34], organic polymers [35], and biochar [36], and many waste materials, such as fly ash [37], reused sanding wastes [38], biomass [39], and water treatment residuals (WTRs) [40,41], have been used for the removal of heavy metals by adsorption. The most effective heavy metal adsorbents, especially for arsenic, are adsorbents based on metal oxides (Fe, Al, Mn oxides), such as WTRs, bog iron ores [42], ferrihydrite [43], goethite [44], layered double hydroxide (LDH) [45], Sn/Ti-Mn binary metal oxides [46,47], Al/Fe oxide-oxyhydroxide composite powders [48], and red mud [49].…”

Equilibrium and Kinetic study of lead and copper ions adsorption on Chitosan-grafted-poly acrylic acid synthesized by Surface-initiated Atomic Transfer Polymerization

“…The presence in the water of metals dangerous to health generated by industrial activities, such as lead and copper, have led to the search for removal efficient methods that do not generate problems of subsequent contamination; currently, lead and copper are reported between the most toxic metals to the environment [1]. From lasts decade, they have drawn much attention owing to its impact on the public health and toxicity; the Environmental Protection Agency of the United States, EPA has classified some heavy metal ions as priority pollutants due to its high degree of toxicity and hazardous when they are presented in water and recently have published "Use of Lead Free Pipes, Fittings, Fixtures, Solder and Flux for Drinking Water; Extension of Comment Period" [2].…”

Novel 3D lightweight carbon foam as an effective adsorbent for arsenic(v) removal from contaminated water

“…[31][32][33] It is known that porous carbon materials, which are thermally stable, chemically inert and low cost, show better adsorption property for heavy metals. Furthermore, Burke et al 34 and Lee et al 35 reported that mesoporous carbon foam have been used for the removal of copper and lead. Though signicance progress has been made for the removal of heavy metals from water.…”
