Adsorption process is widely used for the removal of wastewater contaminants. Classic adsorption units are fixed beds and membrane filtration systems. In this work a novel configuration bench scale spinning adsorber submerged filter proposed. Different prototypes cylindric, truncated cone or prismatic adsorbers were studied using activated carbon different particle sizes GAC (1.5 mm, Granulated...

This work investigates the liquid-phase adsorption of n-butanol on Amberlyst™15 in temperature range 295–323 K at different initial adsorbate concentrations. The adsorbent was characterized by N2 physisorption, Fourier transform infrared pyridine, scanning electron microscopy, and powder X-ray diffraction. data obtained confirmed an structure with two porosity levels amorphous polymer structure...

The aim of this study was to examine the use of polyamide 6 nanofibers as an adsorbent material for removal of dye on textile wastewater. Simulated wastewater of acid dye (namely Color Index Acid blue 41) was used for experiment test with concentration of 0.01, 0.02 and 0.03g/L. Two kinds of electrospun polyamide 6 nanofibrous membranes with weight per unit area respectively 1.0 and 2.9g/m2 wer...

We demonstrate the application of artificial neural network (ANN) models to reverse Monte Carlo based thermodynamic calculations. Adsorption isotherms are generated for 2D square and triangular lattices. These lattices considered because their importance catalytic applications. In general, configurational free energy terms that arise from adsorbate arrangements challenging handle typically eval...

The vibrational properties of carbon monoxide adsorbed to the copper (100) surface are explored within density-functional theory. Atoms of the substrate and adsorbate are treated on an equal footing in order to examine the effect of substrate–adsorbate coupling. This coupling is found to have a significant effect on the vibrational modes, particularly the in-plane frustrated translation, which ...

The specific surface area of a powder is determined by physical adsorption of a gas on the surface of the solid and by calculating the amount of adsorbate gas corresponding to a monomolecular layer on the surface. Physical adsorption results from relatively weak forces (van der Waals forces) between the adsorbate gas molecules and the adsorbent surface of the test powder. The determination is u...
