“…The GO adsorption rate is related to the degree of oxidation so that highly oxidized GO displayed a superior adsorption rate than the GO with a lower oxidation degree (Thangavel and Venugopal, 2014). In recent years, many research investigations have been conducted for the removal of drugs using GO, for example, adsorption of trimethoprim and isoniazid antibiotics (Çalış kan Salihi et al, 2020), norfloxacin (Moreira et al, 2020), naproxen (Ci gero glu et al, 2020), cephalexin (Wernke et al, 2020), sodium diclofenac (Guerra et al, 2019), and fluoroquinolones (ciprofloxacin, norfloxacin, and ofloxacin) (Yadav et al, 2018) from aqueous solutions.…”

“…2d), and other critical characterization techniques were employed to clarify the role of GQD edges in the adsorption of organic pollutants. 31 Although electrostatic interactions are typically considered the driving force to bind the pollutants to the GO surface, Hbonding, 32 π-π stacking, 33 cations-π, 34 and hydrophobic interactions 35 should also not be ignored by considering the complex structure of GO, which includes numerous oxygen groups, sp 2 -conjugated carbon domains, and hydrophobic regions. 36 Furthermore, the challenges in recycling and reusing GO colloids can be resolved by implementing their unstable feature in the presence of certain contaminants.…”

In order to remove toxic graphene oxide (GO) from aqueous solution, attapulgite (ATP) was used as adsorbent to recycle it by adsorption. In this paper, the effects of different pH, adsorbent mass, GO concentration, time and temperature on the adsorption of GO by attapulgite were studied, and the adsorption performance and mechanism were further explored by XRD, AFM, XPS, FTIR, TEM and SEM tests. The results show that when T = 303 K, pH = 3, and the GO concentration is 100 mg/L in 50 mL of aqueous solution, the removal rate of GO by 40 mg of attapulgite reaches 92.83%, and the partition coefficient Kd reaches 16.31. The adsorption kinetics results showed that the adsorption equilibrium was reached at 2160 min, and the adsorption process could be described by the pseudo-second-order adsorption equation, indicating that the adsorption process was accompanied by chemical adsorption and physical adsorption. The isotherm and thermodynamic parameters show that the adsorption of GO by attapulgite is more consistent with the Langmuir isotherm model, and the reaction is a spontaneous endothermic process. The analysis shows that attapulgite is a good material for removing GO, which can provide a reference for the removal of GO in an aqueous environment.
