“…Because of complex molecular structure, typical dyes are stable, resistant to light, heat, and oxidizing agents [ 12 ] making conventional treatment techniques like: ion exchange [ 13 ], membrane filtration [ 14 ], irradiation [ 15 , 16 ], electrokinetic coagulation [ 17 ], oxidation [ 18 ], chemical coagulation-flocculation [ 19 ], ozonation [ 20 ], biodegradation [ 21 , 22 , 23 , 24 ] unsuitable for water purification. Although some of them seem to be effective for dye removal, closer insight into the specific character of the mentioned methods reveals lots of disadvantages.…”

Mesoporous carbons with differentiated properties were synthesized by using the method of impregnation of mesoporous well-organized silicas. The obtained carbonaceous materials and microporous activated carbon were investigated by applying different methods in order to determine their structural, surface and adsorption properties towards selected dyes from aqueous solutions. In order to verify applicability of adsorbents for removing dyes the equilibrium and kinetic experimental data were measured and analyzed by applying various equations and models. The structural and acid-base properties of the investigated carbons were evaluated by Small-Angle X-ray Scattering (SAXS) technique, adsorption/desorption of nitrogen, potentiometric titration, and Transmission Electron Microscopy (TEM). The results of these techniques are complementary, indicating the type of porosity and structural ordering, e.g., the pore sizes determined from the SAXS data are in good agreement with those obtained from nitrogen sorption data. The SAXS and TEM data confirm the regularity of mesoporous carbon structure. The adsorption experiment, especially kinetic measurements, reveals the utility of mesoporous carbons in dye removing, taking into account not only the adsorption uptake but also the adsorption rate.

Water‐in‐oil emulsions separation plays a critical role in industrial wastewater treatment. Membrane technology has attracted much interest in water‐in‐oil emulsions separation field for its excellent separation performance and facile processing method. However, versatile membrane with better solvent‐resistance is still absent in chemical industry. In this work, oxidized polyarylene sulfide sulfone (O‐PASS) membrane was severed as substrate, on which a hydrophobicity surface was built via coating of octadecyltrichlorosilane (OTS). And polydopamine (PDA) layer was employed and acted as connector between OTS and O‐PASS membrane due to its abundant active hydroxyl group. The maximum water contact angle was 132.6° indicating good hydrophobicity of the membrane. Finally, the OTS/PDA/O‐PASS composite membranes showed good separation performance for corrosive emulsions: the rejection and flux were 93.0% and 10.0 L/m2h for water‐in‐dichloromethane emulsions, and the rejection and flux were 92.3% and 34.6 L/m2h for water‐in‐n‐hexane emulsions. The OTS/PDA/O‐PASS composite membrane is a new candidate membrane for water‐in‐oil emulsions separation. In addition, the superior performance of the composite membrane under harsh environment conditions ensures its usefulness in resistance aggressive solvent.
