Adsorption of diclofenac sodium from aqueous solutions on expanded graphite

Degradation of diclofenac aqueous solutions in a 3D electrolytic reactor using carbon-based materials as pseudo third electrodes in fluidized bed, anodic and cathodic configurations

“…For example, Vedenyapina et al studied DCF adsorption (400 mg L − 1 ) using a GEG prepared from foundry graphite by a perchloric acid and thermal process. They obtained a Q 0 of 330 mg DCF g GEG − 1 [37]. While our results on the GEG (SIGRATHERM® GFG 1200) are lower than this value, these differences highlight the challenges of comparing different carbon materials in adsorption and catalytic studies because of their surface physicochemical properties can be significantly different due to varying sourced materials, chemical modifications, and pretreatments.…”

“…To fill this knowledge gap, the present work proposes the use of two different types of commercial porous and non-porous carbonaceous materials: a GAC (Calgon Filtrasorb® 200) and a granular expanded graphite (GEG) (SIGRATHERM® GFG 1200). The latter GEG material has received particular attention in recent decades for its adsorption properties of various organic substances including DCF [37]. In addition, GEG is also an excellent electrical conductor, which is favorable for electrochemical applications requiring improved electrical current transfer [38][39][40].…”

Porous organic nanofiber polymers as superfast adsorbents for capturing pharmaceutical contaminants from water

“…Remarkably, compared to the benchmark adsorbents in the literature (Table S2 †), PONF exhibited the highest adsorption capacities for the three PPCP compounds. [40][41][42][52][53][54][55][56][57][58][59][60][61][62][63][64][65] Furthermore, PONF exhibited steep adsorption isotherms at low concentrations of the three PPCP compounds, which suggests that PONF may be able to remove trace amounts of PPCP contaminants from aqueous media.…”

Magnetic and Hydrophobic Composite Polyurethane Sponge for Oil–Water Separation

“…Therefore, it is necessary to prepare a PU sponge with low cost, simple preparation process, and magnetic properties, which can be applied to oil-water separation. Expanded graphite (EG) is a porous worm-shaped material formed by the expansion of natural graphite flakes at high temperatures, and it is extremely inexpensive and has a strong adsorption capacity [28][29][30][31][32]. Stearic acid is a water-insoluble fatty acid, which has good hydrophobic properties and is inexpensive [33][34][35][36].…”
