The primary judgment is that the process is multilayer adsorption, so the surface areas of MWCNTs are not the only determination factor in the adsorption.…”

“…Most of the processes already in practice are commercially not feasible to achieve the required stringent disposal standards in surface water bodies [5]. Adsorption is another method in which activated carbon is one of the most well-known adsorbents; however, the high cost of this adsorbent has inspired search for the development of alternatives from cheaper and abundant materials [8][9][10][11][12][13][14][15][16].…”

Clay‐based masonry materials such as brick and tile constitute a significant part among construction and demolition debris. These bulky materials, if not reused or recycled, are mostly landfilled for disposal. In this study, three types of these waste materials including hand‐made bricks (H‐bricks), machine‐made bricks (M‐bricks), and ceramic tiles were employed and their capability for adsorption of Zn2+ was investigated through batch experiments. The characterization of the adsorbents was performed by using X‐ray diffraction, X‐ray fluorescence, optical microscopy, scanning electron microscopy imaging, and Brunauer–Emmett–Teller analysis. The effect of initial zinc concentration, contact time, solution pH, and adsorbent particle size on Zn2+ adsorption onto the adsorbents was studied. The results indicated that the removal efficiency is reduced by increasing initial zinc concentration. Furthermore, M‐brick and tile showed better adsorption capacity for finer sizes, whereas uptake capacity of H‐brick decreased by size reduction. Both linear and nonlinear regression were then applied to the data and revealed that adsorption onto M‐brick followed Redlich–Peterson isotherm, whereas the data of H‐brick and tile were best modeled by Koble–Corrigan isotherm. The maximum Zn2+adsorption capacities for M‐brick, H‐brick, and tile were obtained as 3.9, 2.45, and 1.76 mg g−1, respectively. Moreover, the kinetic data were modeled by using four well‐known models. The adsorption kinetics of Zn2+ onto M‐brick and tile was best represented by Elovich, and kinetic behavior of H‐brick was found to obey the pseudo‐second‐order model. © 2013 American Institute of Chemical Engineers Environ Prog, 33: 777–789, 2014

Graphene oxide (GO) was synthesized by chemical oxidation method and used to remove nickel (Ni(II)) from aqueous solutions in the presence of Paecilomyces cateniannulatus (P. cateniannulatus). Based on characteristic results, it was demonstrated that P. cateniannulatus was easily combined with carboxyl groups of GO by covalent bond. The adsorption results showed that P. cateniannulatus facilitated the adsorption of Ni(II) on GO over a wide range of pH. The maximum adsorption capacities of GO+P. cateniannulatus and GO calculated from Langmuir model at pH 4.0 and T=303 K were 104.2 and 81.3 mg·g −1 , respectively. According to the analysis of thermodynamic parameters, the adsorption of Ni(II) on GO+P. cateniannulatus was endothermic and spontaneous. The highlight of this study quantitatively assessed the effect of bacteria on the fate and transports of heavy metals in near-surface geologic systems.
