To overcome the limits of low adsorption capacity and the separation difficulty of solid from liquid phase for graphene oxide (GO), a novel nanocomposite graphene oxide-manganese oxide (GOMO) was facilely fabricated under ultrasonic radiation. The structures and micro-morphology of the products were characterized by fourier transform infrared (FT-IR) spectroscopy, raman shift spectroscopy, X-ray diffraction (XRD) pattern and scanning electron microscopy (SEM). The effect of solution pH, adsorbent dose, contact time, initial uranium concentration, ionic strength and temperature on uranium removal efficiency was studied by batch adsorption experiments. The product GOMO was used to examine the feasibility of the removal of high salt content in uranium-containing wastewater. The adsorption results were fitted using the Langmuir and Freundlich isotherm models. The kinetic parameters in the adsorption process were measured and fitted. Five adsorption/desorption cycles were performed using 3 M HNO3 as the regenerant in order to evaluate the reuse of GOMO.

“…Nevertheless, the hydrophilic effect was resulted from some functional hydroxyl groups such as SiOH, and -MgOH on the edge surfaces [31]. The faces and the edges of the clay particles can adsorb polar pollutants, some anions and cations, from water.…”

a b s t r a c tFe 3 O 4 /montmorillonite nanocomposite (Fe 3 O 4 /MMT NC) was synthesized for removal of Pb 2+ , Cu 2+ and Ni 2+ ions from aqueous systems. The nanoadsorbent was characterized by X-ray diffraction and transmission electron microscopy and mean diameter of magnetic nanoparticles was about 8.24 nm. The experiments were designed by response surface methodology and quadratic model was used to prediction of the variables. The adsorption parameters of adsorbent dosage, removal time, and initial heavy metal ions concentration were used as the independent variables and their effects were investigated on the heavy metal ions removal. Variance analysis was utilized to judge the adequacy of the chosen models. Optimum conditions with initial heavy metal ions concentration of 510.16, 182.94, and 111.90 mg/L, 120 s of removal time and 0.06 g/0.025 L, 0.08 g/0.025 L, and 0.08 g/0.025 L of adsorbent amount were given 89.72%, 94.89%, and 76.15% of removal efficiency Pb 2+ , Cu 2+ and Ni 2+ ions, respectively. Prediction of models was in good agreement with experimental results and Fe 3 O 4 /MMT NC was found successful in removing heavy metals from their aqueous solutions.

“…The objective of this study is to investigate the potential of using a new filter aiding material, namely talc, to enhance the removal of dispersed solids in a multi-media filtration process. Talc was previously investigated in adsorption applications and was found to have good potential for adsorbing toxic compounds from aqueous solutions [13,14]. However, no previous studies looked into the potential of using talc as a filter aiding material to enhance the removal of suspended particles from aqueous solutions.…”
