Produced water, which contains a high amount of hydrocarbons, heavy metals, and other pollutants, is one of the major waste streams in the Niger Delta's oilfields and refineries. The treatment of produced water can be done in a variety of ways, including physical (desalination, membrane separation and, adsorption), chemical (precipitation, absorption and, oxidation), and biological. The heavy metals and contaminants in the wastewater pose a threat to living creatures and the environment. This research evaluates the effectiveness of Activated carbon modified with Graphene oxide, a new thriving material for researchers derived from graphite, to improve the adsorption capacity of coconut husk using the “wet impregnation technique” for the removal of heavy metals from produced water. Batch adsorption of the pollutant was studied for the Activated Carbon, and the modified activated carbon (AC-GO) at a time intervals, for each of the adsorbents. The removal efficiency of the adsorbent was found to increase proportionately from 6.71% to 92.96%, 3.01% to 52.23% and 51.28% to 67.77% for Cd, Ni and Pb respectively with increasing contact time. Atomic absorption spectroscopy (AAS) analysed the treated produced water samples. The adsorption isotherms and kinetics studies of the adsorbed metals were evaluated and correlated with empirical models.

“…Graphene oxide consists, on its surface, numerous and different types of large amounts of oxygen atoms in the form of hydroxyl, epoxy, phenol, and carboxyl groups. Due to these functional groups on graphene oxide, it is extremely hydrophilic and can be utilized in both biological and aquatic situations [15,16].…”

“…In particular, there is a need for finding effective, inexpensive, and efficient materials for the adsorption processes. The removal of BPA from aqueous solutions by adsorption was demonstrated in several investigations, including hydrophobic zeolite [20,21], cetylpyridinium bromide (CPB) and N-cetyl-N, N, N, trimethylammonium bromide (CTAB) modified natural zeolites [21][22][23], various surfactants-modified clays [24][25][26], combined use of biopolymer chitosan and oxidoreductase polyphenol oxidase [27], chitosan [28], waste biomass [29][30][31] composites and polymeric materials [32,33], nano-adsorbents materials such as 2-vinylpyridine functionalized magnetic nanoparticles [34], and graphene oxide [35]. Among the nano-adsorbents used for organic and inorganic pollutants removal, gamma-alumina nanoparticles have gained extensive attention as reliable, sustainable, and eco-friendly materials [36][37][38][39][40][41][42][43].…”

Gamma-alumina nanoparticles (γANPs) were obtained from a low-cost process by using natural bauxites. The γANPs materials were characterized by X-ray powder diffraction (XRPD), Fourier-transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) theory, scanning electron microscopy (SEM), atomic force microscopy (AFM), and were functionalized with N-cetyl-N, N, N, trimethylammonium bromide (CTAB), leading to CTAB modified γ-alumina nanoparticles (γANPs-CTAB). These novel functionalized γANPs-CTAB were characterized by XRPD, FTIR, and were used as an adsorbent for bisphenol-A (BPA) removal from water. Batch investigations were conducted under different experimental conditions (e.g., adsorbent dose, agitation time, initial concentration, and pH and surfactant loading) in order to optimize BPA adsorption and to identify the adsorption mechanisms in the system γANPs-CTAB-BPA. The effect of pH on the adsorption showed that the quantity of BPA removed increased remarkably until the pH value was 4, then remained almost constant until the pH value was up to 10, and then decreased for pH values greater than 10. For an initial BPA concentration of 20 mg/L and an adsorbent dose of 12.5 g/L at a pH value of 10, the removal efficiency achieved was 91.80 ± 0.21%. The adsorption mechanism was perfectly described by pseudo-second-order kinetics and the Langmuir isotherm. γANPs-CTAB materials were found to be effective adsorbents for BPA removal from water.
