Separate As(V) from solution by mesoporous Y-Al binary oxide: batch experiments

Batch Adsorption From Solution

A batch adsorption equation was derived by integrating an irreversible rate equation obtained by neglecting the desorption term of the Langmuir adsorption-rate equation. The integrated equation was in reasonably good agreement with experiment and provided a means for determining from the data the parameters gQ and ku These constants, namely, the adsorptive capacity and the adsorption rate const...

Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System

Mesoporous Carbon Modified with Iron Oxide Based Magnetic Nanomaterials for Removal of Malachite Green Dye From Aqueous Solution

Mesoporous carbon (CMK-3) modified with Fe3O4 nanoparticles has been successfully synthesized and characterized by powder X-ray diffraction (XRD), N2 adsorption-desorption, scanning electron microscope (SEM) and transmission electron microscopy (TEM).The results depict that the synthesized Fe-CMK-3 preserved the ordered mesoporous structure of CMK-3, and magnetic species were dispersed insi...

Topology, Crystallized (Experiments): P. Dziawa et al., arXiv:1206.1705; S.-Y. Xu et al., arXiv:1206.2088

A key difference between quantum Hall phases induced by a magnetic field and topological insulator phases induced by spin-orbit coupling is that the latter depend crucially on a symmetry, time reversal. The action of time-reversal symmetry on electrons leads to a new kind of topological invariant in twodimensional systems [1] that takes only two possible values: if this “Z2 invariant” is even, ...

Complex Roles of Solution Chemistry on Graphene Oxide Coagulation onto Titanium Dioxide: Batch Experiments, Spectroscopy Analysis and Theoretical Calculation

Although graphene oxide (GO) has been used in multidisciplinary areas due to its excellent physicochemical properties, its environmental behavior and fate are still largely unclear. In this study, batch experiments, spectroscopy analysis and theoretical calculations were addressed to promote a more comprehensive understanding toward the coagulation behavior of GO onto TiO2 under various environ...
