“…Activated carbons have become of special interest because properties like their large surface area, internal porosity, chemical and thermal stability, and presence of functional groups on their surface have made them useful in a variety of fields, including electronics, electrochemistry, metallurgy, catalysis, and adsorption. Adsorption is one of the main applications of activated carbons because they make it possible to concentrate pollutants for later disposal [6–12] …”

Aiming to add value to the ever-increasing amount of residues from the palm oil industry around the world, lignocellulosic waste from palm oil (Lp) was used in this study to prepare activated carbons (ACLp) by chemical activation using KOH at 700 °C developing an area up to 1683 m 2 g À 1 , this value was higher than that obtained for a sample of activated carbon prepared from commercial lignin (ACLc) of 588 m 2 g À 1 . The activated carbons were deeply characterized by different techniques as SEM, FTIR, TGA, and nitrogen adsorption isotherms. The adsorption capacity of the obtained activated carbons for methylene blue (MB) was assessed. According to the results of the mathematical fits performed to the adsorption process, the adsorption isotherm showed a better fit to the Langmuir-Freundlich model, with a maximum adsorption capacity of 188 and 51 mg g À 1 for ACLp and ACLc respectively. In addition, its adsorption kinetics was found to fit better to the pseudo-second-order kinetic model. Additionally, the ΔG 0 value was lower for ACLp (À 31 KJ mol À 1 ) than for ACLc (À 26 KJ mol À 1 ) showing that the interaction between the MB and ACLp is more favorable.

“…Molecules of organic water contaminants such as MB and MO can accumulate in solutions before the adsorption process (i.e., aggregation phenomenon) [21]. The increment of the n parameter with increasing temperature indicated that the solution's aggregation of MO and MB molecules was endothermic [1]. Additionally, the free movement of MO dye (molecular dimension of 1.2 nm) favored the MO-MO interface, and thus, its molecular aggregation was higher than that of MB dye [36].…”

“…Different industrial activities, such as textiles, printing, food, and cosmetics, use organic dyes as coloring materials to supply products with distinctive colors [1][2][3][4]. In particular, anionic methyl orange (MO) and cationic methylene blue (MB) are documented as stable dyes under a wide range of light, heat, and chemical reagents, and thus, MO and…”

Pure rutile TiO2 nanoparticles (Rt) were combined with exfoliated black clay (BC) to prepare a new composite for water decontamination, in particular, for the uptake of methylene blue (MB) and methyl orange (MO) dyes. The as-prepared Rt/BC was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Field emission scanning electron microscopy (FESEM) techniques, and the dyes’ adsorption isotherms at three temperatures (i.e., 25, 40, and 50 °C) were studied. The results indicated that Rt/BC displayed a high removal performance for MO (96.7%) and MB (91.4%) at pH 3.0 and 8.0, respectively. Adsorption data of MB and MO were adjusted by a double layer model at all temperatures. The theoretical parameters of this statistical physics model were interpreted to understand the MO and MB adsorption mechanisms at the molecular level. The removed molecules per active site (n) of Rt/BC ranged from 1.12 to 1.29 for MB and 1.47 to 1.85 for MO, thus representing parallel orientation and multi-interactions mechanisms (i.e., van der Waals forces, hydrogen bonding, and electrostatic interactions were involved). The Rt/BC composite had a density of surface adsorption sites of 100 mg/g. The aggregation of MO molecules was high and increased their adsorption capacities (Qsat = 294–370 mg/g) compared to that of MB (Qsat = 214–249 mg/g). Adsorption energies were 9.70–20.15 kJ/mol, and these values indicated that MO and MB adsorption processes were endothermic and occurred via physical interactions. Overall, the low cost, high regeneration performance, and stability of Rt/BC support its application as a promising adsorbent for organic pollutants from wastewaters.

The present work was aimed to evaluate the adsorption properties of activated carbons based on prickly pear seeds (PPS) and conductive polymer matrix based on polyaniline (PANI) for the removal of anionic Congo red (CR) dye from aqueous solutions. The adsorbent was prepared by polymerization of aniline in the presence of activated PPS by phosphoric acid and sodium hydroxide. The samples were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and the Brunauer–Emmett–Teller (BET) methods. The adsorption kinetics were studied using UV-visible (UV/Vis) spectroscopy. The characterization data suggest that the adsorption of the Congo red dye is enhanced because PANI chain molecules, which are especially accountable for removal through π—π interaction and H-bonding with the CR, are adsorbed/tethered onto the acid-activated PPS (PPSH), and thus surmount the mass transfer limitation by being best exposed to the CR-adsorbed molecule. The adsorption kinetics follows the pseudo-second order process. The correlation coefficients (R2) for Langmuir, Freundlich and Tempkin showed that the adsorption values obey Freundlich and Tempkin isotherm models. Moreover, the isotherm was most accurately described by the Freundlich model, and the maximum removal percentage was calculated to be 91.14% under optimized conditions of pH 6.6, 1 g/L of adsorbent dosage, and an initial CR dye concentration of 20 mg·L−1. Importantly, the hybrid adsorbent exhibited the highest adsorption capacity (80.15%) after five cycles of the adsorption–desorption process. Thermodynamic parameters, such as entropy changes, enthalpy changes and Gibbs free energy, were also evaluated. These results indicated that the PANI matrix can generally be better utilized for the removal of Congo red dye when appropriately dispersed on the surface of suitable support materials. These results provide a new direction to promote the separable adsorbents with increasing performance for adsorption of dye impurities from wastewater.
