“…The solution 1 M HCl in 50% methanol used for resin regeneration provided lower desorption efficiency (from 9.1% to 60.3%). The same observation was made by Xing et al [ 28 ] investigating desorption of AR18 from the anion exchange membrane; 90% of AR18 was desorbed using 1 M NaCl in 60% v/v ethanol.…”

Intensive development of many industries, including textile, paper, plastic or food, generate huge amounts of wastewaters containing not only toxic dyes but also harmful auxiliaries such as salts, acid, bases, surfactants, oxidants, heavy metal ions. The search for effective pollutant adsorbents is a huge challenge for scientists. Synthesis of divinylbenzene copolymer with glycidyl methacrylate functionalized with triethylenetetramine (DVB-co-GMA-TETA) resin was performed and the obtained microspheres were evaluated as a potential adsorbent for acid dye removal from dyeing effluents. The sorption capacities were equal to 142.4 mg/g for C.I. Acid Green 16 (AG16), 172 mg/g for C.I. Acid Violet 1 (AV1) and 216.3 mg/g for C.I. Acid Red 18 (AR18). Non-linear fitting of the Freundlich isotherm to experimental data was confirmed rather than the Langmuir, Temkin and Dubinin-Radushkevich. The kinetic studies revealed that intraparticle diffusion is the rate-limiting step during dye adsorption. Auxiliaries such as Na2SO4 (5–25 g/L), CH3COOH (0.25–1.5 g/L) and anionic surfactant (0.1–0.5 g/L) present in the dyeing baths enhance the dye adsorption by the resin in most cases. Regeneration of DVB-co-GMA-TETA is possible using 1 M NaCl-50% v/v CH3OH.

“…Table 2 lists and compares the maximum adsorption capacity of AR88 on various adsorbents. The value of the maximum adsorption capacity determined from the Langmuir isotherm was 309 mg g −1 , which was comparable to the published results in previous papers [28][29][30][31][32][33][34][35] . This result suggests that the PAN-mesoporous as adsorbent was suitable for the removal of AR88 from aqueous solution.…”

A novel nitrogen-containing graphitic mesoporous carbon was prepared through Mno-templated method using polyacrylonitrile (PAN) as both carbon and nitrogen sources, and MnCO 3 as both template and catalyst precursors. The effects of preparation conditions on the physicochemical properties of obtained samples were systematically investigated. the results showed that as the decrease of the weight ratios of PAN and MnO (2:1-1:4), the increase of carbonization temperature (700-900 °C) and pre-oxidation temperature (180-200 °C), the samples had higher specific surface area, mesopores volume and ratios, up to 507 m 2 /g, 0.824 cm 3 /g and 96.83%, respectively. Moreover, the prepared samples presented relatively high graphitic degree and nitrogen contents (~2.21%). The adsorption capacity for acid red 88 (AR88) was as high as 309 mg/g, which were dramatically affected by the mesoporous properties and c-and n-containing groups on the surface of prepared carbon. the rich graphic carbon and pyridine-n in mesoporous carbon generated π-π dispersion and electrostatic interaction with AR88, respectively, which jointly were responsible for the adsorption process. The results of the isotherm and kinetic studies indicated that the AR88 adsorption on mesoporous carbon could be well depicted using Langmuir model and pseudo-2 nd -order model.Recently, the demand for dyes is increasing, with the fast development of industries, including textile, printing, paper making, cosmetic, etc. The dye wastewater has gradually become one of the vital pollutants, which seriously affects both human beings' health and environment. Thus, it is significantly important for the removal of dye pollutants from wastewater before discharging into environment. However, it is a great challenge to treat dye wastewater, because of its high resistance to photo-degradation, oxidation and bio-degradation 1 . It was reported that the adsorption by mesoporous carbon (i.e. pores size from 2 to 50 nm) is a desirable method for the removal of dye pollutants with large molecules diameters, with many advantages such as easy operation, high efficiency, and the recycle of dye 2-4 . In comparison with the microporous adsorbent, the mesoporous carbon possessed higher adsorption capacity for the large dye molecules 5-7 . The adsorption rate could also be significantly enhanced by introducing the mesoporous structure into the carbon materials 8 .Normally, various hard templates including zeolites, mesoporous silica are used to prepare the mesoporous carbon by removing these ordered structural frameworks. This strategy has been given extensive attention in the literature due to the high stability of templates and precise control for porous structure 9 . However, when removing these hard templates, some strong corrosive agents like hydrofluoric acid and sodium hydroxide are used, which will always cause unavoidable corrosion, and the templates are obliged to be wasted 10 . In this way, the high preparation cost of the template method seriously hinders its application in practi...

Magnetic multi‐walled carbon nanotubes‐Fe3C nanocomposite was synthesized by chemical vapor deposition process and was used as an adsorbent for the removal of acid dye Acid Red 88 (AR88) from aqueous solution. The effects of various parameters such as initial AR88 concentration (10–58 mg L−1), pH (3.1–11.3) and temperature (20–60°C) were investigated. The properties of this adsorbent were characterized by X‐ray diffraction, high‐resolution transmission electron microscopy, energy dispersive X‐ray analysis, fourier transform IR, N2 adsorption/desorption isotherms, and particle size distribution by laser diffraction. The experimental data were analyzed by the Langmuir and Freundlich models of adsorption. Equilibrium data fitted well with the Freundlich model. Kinetic adsorption data were analyzed using the Lagergren pseudo‐first‐order kinetic model, the pseudo‐second‐order model and the intraparticle diffusion model. The regression results showed that the adsorption kinetics was more accurately represented by pseudo‐second‐order model. Thermodynamics parameters, Gibbs free energy (ΔG0), enthalpy (ΔH0), and entropy (ΔS0), were calculated. All ΔG0 values were negative. The values of ΔH0 and ΔS0 were −4.70 and −7.98 J mol−1 K−1, respectively, indicating that adsorption of AR88 onto magnetic multi‐walled carbon nanotubes nanocomposites was spontaneous and exothermic in nature.
