“…Increase in the adsorption capacity of the aminated resin was attributed to the H-bonding between p-nitrophenol and dimethylamino group. More studies on the removal of phenols by various polymeric adsorbents can be found in the literature [15][16][17][18][19][20][21][22][23][24][25][26][27].…”

“…So the Freundlich isotherm model can be better fitted to the adsorption data. Besides, the values of n in the Freundlich isotherm model are over 1.0, which suggest a favorable adsorption [2]. The fact that low temperature is favorable for the adsorption is supported by the values of K F and n decreasing with the temperature increasing [39].…”

“…As a representative in water environment, phenol is a toxic and carcinogenic substance when absorbed through the respiratory organ, skin, and the alimentary canal [1,2]. Ingesting such contaminated water in the human body causes cell damage, protein degeneration, tissue erosion and paralysis of the central nervous system and also damages the kidney, liver and pancreas [3].…”

The organic-inorganic self-doped poly (vinyltrimethoxy silane-ethylene glycol dimethacrylate) (VE resin) was synthesized by solution polymerization, hydrolysis and dehydration condensation. In this method, ethylene glycol dimethacrylate (EGDMA) was used as cross-linked reagent to form a three-dimensional network structure. Then, the system was prepared by radical polymerization in the presence of the hydrolysis of -OCH 3 and the dehydration condensation of Si-OH. The maximum adsorption capacity 75.68 mg g -1 was achieved when pH was 6, the contact time 60 min, the adsorbent dose 0.1 g, the initial concentration 3000 mg L -1 and the temperature 293 K. The adsorption kinetics followed the pseudo-second-order kinetic model, and the intra-particle diffusion was but not the only rate-limiting step. Adsorption isotherms of phenol were linearly correlated and found to be well represented by the Freundlich model. Thermodynamic parameters such as changes in the enthalpy (DH), free energy (DG) and entropy (DS) indicated that the adsorption process of phenol on VE resin were physical and exothermic. After four regeneration recycles, the adsorption capacity of VE resin remained at 95.04 % of the initial value, which illustrated that it possessed good regeneration capacity.

“…[10] One of the methods is the static sessile drop method, which is recommended in the literature from a comparison of five different contact angle measurement methods. [11] For the static sessile drop method, a camera, a light source, and a stage are required. The camera captures a photograph of a drop of liquid on a flat, solid material lit by a parallel light beam.…”

The contact angle of a gas-liquid-solid system plays a significant role in predicting flow patterns in microchannels for multiphase flows. The contact angle, which is a result of surface forces, is strongly influenced by the channel material. In the present study, we describe contact angle measurements and simulations of flow in a microchannel for the multiphase system hydrogen and nitrobenzene. Contact angles for nitrobenzene-hydrogen-stainless steel and nitrobenzene-hydrogen-carbon systems were measured using the sessile drop method at various pressures. Simulation of the two-phase system was performed using ANSYS FLUENT. The static contact angle is used as a boundary condition. The results from simulation of flow for a wide range of contact angles and the measured contact angles are presented. Experimental observations and simulation results agree in that the contact angle must be smaller 90• to obtain small bubbles and to increase the gas-liquid interfacial surface area.
