“…Besides membranes chemically modified GO and GO based composites are effective adsorbents for removal various pollutions from wastewater [110] including heavy metal ions [111][112][113]. Moreover the GO based sorbents can be successfully regenerated for subsequent use [114,115].…”

Graphene oxide (GO) is useful and promising material for graphene based applications in electronic, optics, chemistry, energy storage, and biology. At the beginning of graphene history GO was only a simple and cheap step for preparation of single and multilayer graphene films and bulk structures by reduction. The further studies revealed the substantial structure imperfection of graphene oxide derived materials due to the defects in initial graphite and incompletion of reducing process. However, the results of recent research demonstrated a great amount of unique chemical, optical and electronic properties of graphene oxide that allow regarding it as independent nanomaterial possessing a large area of applications. In general, it represents the ultra-large organic molecule containing 2D carbon mesh. Unlike conventional graphene it provides wide range of chemical methods for attachment of various functional groups to its surface for control optical transparency, electrical and thermal conductance. Recently developed methods for preparation of graphene oxide derivatives saturated by carboxyl groups open the new attractive application areas in green technologies including energy storage and utilizing nuclear wastes. The goal of the review is to summarize the results of recent studies of graphene oxide, derivatives and reveal the most promising directions to focus the efforts of researchers.

“…An ion exchange reaction between heavy metal ions and protons on -COOH or -OH groups is one adsorption mechanism. Metals are predominately adsorbed by a combination of ion exchange with carboxyl functional groups, and the possible relevant reactions between the oxygenous functional groups on the GO-NH 2 surface and the heavy metal ions may be represented as follows [14,35] Surface complexation between heavy metal ions and various functional groups plays a significant role in the adsorption of metal ions. After APTES supplied -NH 2 to GO, the adsorption capacity increases owing to complexation between the amino groups and heavy metals [4].…”

“…The electrostatic attraction between positively charged heavy metal ions and the negatively charged surface of GO-NH 2 provides a driving force for the adsorption process. The carboxyl and hydroxyl groups on the GO-NH 2 surface can remove metal ions via electrostatic attraction, and the relevant reaction can be expressed as [14]:…”

“…Graphene is difficult to be modified directly owing to the inactive surface. Graphene oxide (GO) can be easily functionalized and used to explore for sorbents [1,14]. GO contains plenty of oxygen-containing functional groups (such as hydroxyl, epoxy, carbonyl and carboxyl groups), and it also exhibits hydrophilic properties.…”

“…GO contains plenty of oxygen-containing functional groups (such as hydroxyl, epoxy, carbonyl and carboxyl groups), and it also exhibits hydrophilic properties. However, the direct application of GO to remove heavy metal ions has several disadvantages [14]. GO tends to aggregate with layered structures owing to its strong inter-planar interactions, which leads to reduced adsorption capacity and adsorption efficiency.…”

AbstractAmino-functionalized graphene oxide (GO-NH2) was synthesized by grafting (3-aminopropyl) triethoxysilane on the graphene oxide (GO) surface. The GO-NH2 with high surface area and numerous active sites can efficiently adsorb Cr(VI), Cu(II), Pb(II) and Cd(II) ions. The maximum adsorption capacities of GO-NH2 for Cr(VI), Cu(II), Pb(II) and Cd(II) were 280.11, 26.25, 71.89 and 10.04 mg g−1, respectively. The pseudo-first-order and pseudo-second-order kinetic models were employed to describe the kinetic processes. The experimental data agreed well with the pseudo-second-order kinetic equation, and the adsorption of heavy metals onto GO-NH2 occurs via chemical adsorption. The characteristics of Cr(VI), Cu(II), Pb(II) and Cd(II) in the GO-NH2 adsorption processes were analyzed using the Langmuir and Freundlich isotherm models. The adsorption processes of Pb(II) and Cd(II) on GO-NH2 were fit by the Langmuir model. The Freundlich isotherm model was well correlated to Cr(VI) and Cu(II). The GO-NH2 is a promising material for the removal of heavy metal ions from industrial wastewater. This study provides an effective pathway to process industrial wastewater, and the GO-NH2 has a good adsorption effect for the treatment of heavy metals in industrial wastewater.
