“…Due to the CDC structural and tunable properties, it can provide more binding sites that might improve the adsorption capacity of different pollutants [37]. In this regard, CDCs were utilized for the adsorptive removal of cytokines [38], acetaldehyde [39], carbon dioxide [40], different electrolytes [41] and phosphate [42]. Moreover, Alvarez et al [43], in their turn explored the kinetics and isotherms of the removal of diclofenac and metronidazole from water solutions using CDC produced from TiC powder at various synthesis temperatures (800-1400°C).…”

Purpose Pharmaceuticals are becoming one of the largest environmental concerns when it comes to the water treatment industry. Increased usage of these chemicals poses a serious risk to ecology and human health due to their leakage into surface waters. In the present study, carbide derived carbon (CDC) was used for the first time as a new adsorbent to remove ibuprofen from synthetic water and wastewater effluent. Methods The morphology, chemical composition, surface area and surface charge of the CDC particles were investigated using the transmission electron microscopy, scanning electron microscopy, energy dispersive spectroscopy, Fourier transform infrared spectroscopy, BET analysis and zeta potential measurements. The effects of CDC dosage, temperature, initial pH and agitation speed on the adsorption process were examined by using batch adsorption experiments. Moreover, the adsorption kinetics, thermodynamics, and isotherms were investigated. Results Adsorption and kinetic equilibrium data demonstrate that the adsorption of ibuprofen onto the CDC obeys the Langmuir isotherm model and the kinetics follow the pseudo-2nd order mechanism. The thermodynamic results reveal that ibuprofen adsorption is endothermic and spontaneous. The ibuprofen removal by CDC was mainly controlled by the electrostatic forces at high pH of the feed solution and by the dispersive interactions in acidic media. The ibuprofen removal is promoted at high temperature, high agitation speed and low pH. The highest adsorption capacity of ibuprofen onto the CDC was 367 mg/g at pH 3. Furthermore, the CDC efficiently removed ibuprofen from spiked treated sewage effluent. Conclusions The obtained data indicate that the CDC provides a fast and efficient adsorptive removal of ibuprofen both from a model aqueous solution and treated sewage effluent.

“…The adsorption of PO 4 3À ions is influenced significantly by pH, as it determines the dissociation of PO 4 3À ions, the species of phosphate ion is different at different pH (Almanassra et al 2020;Chen et al 2020). Strong acidic conditions (pH 2) were not tested in this experiment due to high concentration of H þ will destroy the crystal structure and hydrogen bonds of chitosan and made it dissolved.…”

A lanthanum modified sludge biochar chitosan (La-SBC-CS) microsphere was successfully synthesized by dropping sludge biochar (BC) and chitosan into an Lanthanum chloride solution. Batch adsorption experiments were conducted to investigate the adsorption kinetics and isotherm. Application of continuous phosphate removal was achieved via lab-scale column reactors. The phosphate adsorption equilibrium data of the La-SBC-CS fitted well with the Freundlich isotherm, with a maximum adsorption amount of 81.54 mg p/g at 25 °C. Characterization of the adsorbent using scanning electron microscopy analysis (SEM), X ray energy spectrum analysis (EDS), X-ray diffraction analysis (XRD) and Fourier infrared analysis (FTIR) techniques suggested that the possible adsorption mechanisms were electrostatic interaction, ligand exchange and complexation. The La-SBC-CS kept 76.37% phosphate removal efficiency after eight recycles. The results of continuous column reactor experiment demonstrated that the breakthrough time increased with an increase in adsorbents filling height, while it decreased with an increase in initial phosphate concentration or flow velocity. YOON model was applied to the continuous experimental data to predict breakthrough curves and determined the characteristic adsorption parameters for process design. This study indicated that the potential for the practical application of La-SBC-CS in phosphate removal from wastewater.

“…[57] The broad peak gained at 3430 cm À1 refers to the stretching vibration of the O-H bond. [41] Point of zero charge (PZC) The point of zero charge (PZC) is defined as the pH value at which the adsorbent has a net surface charge of zero. The CDC charge was evaluated by measuring the zeta potential values in the pH range between 3 and 10 and the results are illustrated in Figure A3.…”

“…Due to the exceptional surface properties of CDC, it can offer more adsorption sites and provide a higher adsorption capacity of pollutants compared to other adsorbents. As such, CDC has been investigated for the removal of pharmaceuticals, [39,40] phosphate, [41] tetraethylammonium tetrafluoroborate electrolytes, [42] carbon dioxide, [43] acetaldehyde [44] and cytokines. [45] The reported data indicate that CDC could be a promising adsorbent for water treatment applications.…”

The objective of the study is to investigate the potential of carbide-derived carbon (CDC) for the adsorptive removal of nonionic t-octylphenoxy poly ethoxy ethanol (TX-100), anionic sodium dodecylbenzene sulfonate (SDBS) and cationic 1-hexadecylpyridinium bromide (HDPB) surfactants from water. The CDC was characterized using TEM, SEM, FTIR, BET, EDS, XPS methods and zeta potential measurements. The effects of adsorption parameters included initial surfactant concentration, contact time, temperature, and pH of the feed solution were evaluated. The adsorption capacity and mechanism were determined by modeling the isotherm, kinetic and thermodynamic data. The kinetics results demonstrated that the adsorption of the surfactant by CDC obeys the pseudo 2 nd order model. The thermodynamic results have shown that surfactants adsorption by CDC is an endothermic and spontaneous process. The Sips model agreed with the adsorption isotherm data of SDBS with R 2 of 0.987, while both Freundlich and Redlich-Peterson models comply well with adsorption data for TX-100 and HDPB. The hydrophobic and electrostatic interactions were found the dominant mechanisms of the adsorption of the surfactant by CDC. The adsorption capacities of CDC were found to be 442.4, 462.0 and 578.4 mg/g for SDBS, HDPB and TX-100, respectively.
