“…The hierarchical porous activated carbon (SCB-AC) with a high specific surface area (1145 m 2 g À1 ) was produced from sugar cane bagasse via a single-step ZnCl 2 activation and then applied for the adsorption of diclofenac sodium (DFC) from contaminated aqueous solutions in a batch system (Abo El Naga et al, 2019). The adsorption experiments exhibited that the fast adsorption of DFC onto SCB-AC occurred with an adsorption capacity of 315.0 mg g À1 .…”

“…Based on the International Union of Pure and Applied Chemistry (IUPAC) classification, the adsorption/desorption isotherm of LPGC belongs to Type-IV isotherm. It can be seen that the isotherm curve showed a hysteresis loop in the relative vapor pressure range of 0.4-1.0 bar, which demonstrated the presence of a hierarchical micro/mesoporous system on the surface of LPGC (Abo El Naga et al, 2019). This was further confirmed by the Barrett-Joyner-Halenda (BJH) pore-size distribution result.…”

Porous biochar containing graphitic carbon materials have received great attention from various disciplines, especially for environmental pollutant treatment, due to their cost-effective and specific textural properties. This study exhibited a two-step strategy to compose lignin-porous biochar containing graphitic carbon (LPGC) from pitch pine sawdust and investigated its adsorptive removal for diclofenac sodium (DCF) from an aqueous solution. Sulfuric acid (H 2 SO 4 ) was utilized to obtain lignin content from biomass and potassium ferrate (K 2 FeO 4 ) and was adopted to fulfill the synchronous carbonization and graphitization of LPGC. Through slow pyrolysis in atmospheric N 2 (900 • C -2 h), the structure of the as-prepared sample was successfully modified. Using SEM images, a stripped layer structure was observed on the H 2 SO 4 -treated sample for both one-step and two-step activated samples, indicating the pronounced effect of H 2 SO 4 in the layering of materials. K 2 FeO 4 acted as an activator and catalyst to convert biomass into the porous graphitic structure. The BET surface area, XRD and Raman spectra analyses demonstrated that LPGC possessed a micro/mesoporous structure with a relatively large surface area (457.4 m 2 g −1 ) as well as the presence of a graphitic structure. Further adsorption experiments revealed that LPGC exhibited a high DCF adsorption capacity (q max = 159.7 mg g −1 at 298 K, pH = 6.5). The effects of ambient conditions such as contact time, solution pH, temperature, ionic strength, electrolyte background on the uptake of DCF were investigated by a batch adsorption experiment. Results indicated that the experimental data were best fitted with the pseudo second-order model and Langmuir isotherm model. Furthermore, the adsorption of DCF onto the LPGC process was spontaneous and endothermic. Electrostatic interaction, H-bonding interaction, and π-π interaction are the possible adsorption mechanisms. The porous biochar containing graphitic carbon obtained from the lignin content of pitch pine sawdust may be a potential material for eliminating organic pollutants from water bodies.

Diclofenac is an acidic pharmaceutically active compound and one of the most frequently detected ones in wastewater. This review discusses the research progress and innovations made in recent years on the mitigation of diclofenac from aqueous media by adsorption. It was observed that activated carbon by intense physical activation, metal organic frameworks, and chitosan‐cellulose polymeric adsorbents were the best adsorbents for diclofenac removal. Diclofenac sorption follows mainly pseudo‐second order kinetics and was best fit to either Freundlich or Langmuir isotherms. Recent research trends involved the investigation of column and continuous experiments, competitive adsorption, and adsorption with photo‐catalytic degradation. Whilst numerous types of adsorbents have been explored, there is still need for mechanistic studies.
