“…A previous dimensionless analysis for Ni +2 and Co +2 ion depletions under the mass control regime for different flowrates [ 46 ] was carried out, by the authors, considering a characteristic length ( A e −1 ) equal to 27 cm 2 /cm 3 , a diffusion coefficient ( D ) of 0.6 × 10 −5 cm 2 /s [ 60 ], a 97% RVC void volume ( ε ), a solution kinematic viscosity ( μ ) of 1.1 × 10 −2 cm 2 /s, and an electrode geometry of 10.0 cm × 10.0 cm × 1.3 cm. The catholyte was a 0.1 M Na 2 SO 4 solution, adjusted to pH 6 by the addition of H 2 SO 4 and containing an initial concentration ( C i ) of Co +2 or Ni +2 equal to 150 ppm, while the anolyte was a 0.5 M Na 2 SO 4 solution.…”

“…Adsorption provides high metal recovery capabilities with low operative costs; however, it presents low selectivity, and a large amount of waste production. Furthermore, adsorption needs frequent adsorbent regeneration [ 60 , 61 ]. Although photocatalysis does not produce sludge and instantly removes both metals and any organic pollutants present in wastewater, its industrial application is still limited, while it appears to be effective on a laboratory scale [ 62 ].…”

In this paper, a critical review of results obtained using a reticulated vitreous carbon (RVC) three-dimensional cathode for the electrochemical depletion of various divalent ions, such as Cu+2, Cd+2, Pb+2, Zn+2, Ni+2, and Co+2, often present in wastewater, has been carried out. By analyzing the kinetics and fluid dynamics of the process found in literature, a general dimensionless equation, Sh = f(Re), has been determined, describing a general trend for all the analyzed systems regardless of the geometry, dimensions, and starting conditions. Thus, a map in the log(Sh) vs. log(Re) plane has been reported by characterizing the whole ion electrochemical depletion process and highlighting the existence of a good correlation among all the results. Moreover, because in recent years, the interest in using this three-dimensional cathode material seems to have slowed, the intent is to revive it as a useful tool for metal recovery, recycling processes, and water treatments.

“…Recently, GO decorated with fullerenol nanoparticles C 60 (OH) 22 has been proposed for efficient removal of Pb(II) ions in complex matrix samples [ 80 ]. The low solubility of fullerenes in water was overcome by a simple hydroxylation reaction with NaOH in the presence of quaternary ammonium cations and then grafting the obtained fullerenols to the surface of GO.…”

Direct determination of lead trace concentration in the presence of relatively complex matrices is often a problem. Thus, its preconcentration and separation are necessary in the analytical procedures. Graphene-based nanomaterials have attracted significant interest as potential adsorbents for Pb(II) preconcentration and removal due to their high specific surface area, exceptional porosities, numerous adsorption sites and functionalization ease. Particularly, incorporation of magnetic particles with graphene adsorbents offers an effective approach to overcome the separation problems after a lead enrichment step. This paper summarizes the developments in the applications of graphene-based adsorbents in conventional solid-phase extraction column packing and its alternative approaches in the past 5 years.

“…Cleaning the water resources and removing the toxic heavy metal elements by using an absorption based method is suitable for application in a large scale application. Also, this method is cost-effective, re-usability and high efficiency [5]. Graphene oxide and its derivative like reduced graphene oxide have a large surface area, an abundant amount of oxygen-containing functional groups and good mechanical strength.…”

Nowadays, heavy metal pollution has become a serious problem. Toxic heavy metal ions can result in extreme damage to the environment and human society. Under that situation, methods that can remove the heavy metal ions in water have been required. Graphene technology can be widely applied to the removal of heavy metal ions. This article will explain the preparation of graphene oxide and reduced graphene oxide and the efficiency and influence factors of the method applied in water treatment. The method can remove many kinds of mainly occurring toxic heavy metal ions with very high efficiency. Also, large-scale production of graphene oxide can be achieved. The removal of heavy metal ions in water by graphene technology can be a practical method in the water treatment field.
