“…Thus, this model showed good agreement between the predicted and experimental data up to / 0 = 0.5 for all experiments. This trend can be explained by the prevalence of external mass transfer during the initial adsorption in the column [44].…”

The cationic dye malachite green (MG) and the anionic dye Remazol yellow (RY) were removed from aqueous solutions using electrocoagulation-adsorption processes. Batch and continuous electrocoagulation procedures were performed and compared. Carbonaceous materials obtained from industrial sewage sludge and commercial activated carbons were used to adsorb dyes from aqueous solutions in column systems with a 96-98% removal efficiency. The continuous electrocoagulation-adsorption system was more efficient for removing dyes than electrocoagulation alone. The thermodynamic parameters suggested the feasibility of the process and indicated that the adsorption was spontaneous and endothermic (Δ = 0.037 and −0.009 for MG and RY, resp.). The Δ value further indicated that the adsorption process was spontaneous (−6.31 and −10.48; = 303 K). The kinetic electrocoagulation results and fixed-bed adsorption results were adequately described using a first-order model and a Bohart-Adams model, respectively. The adsorption capacities of the batch and column studies differed for each dye, and both adsorbent materials showed a high affinity for the cationic dye. Thus, the results presented in this work indicate that a continuous electrocoagulation-adsorption system can effectively remove this type of pollutant from water. The morphology and elements present in the sludge and adsorbents before and after dye adsorption were characterized using SEM-EDS and FT-IR.

“…Among several physicochemical processes, adsorption is one of the unique and widely used environmental friendly treatment method for wastewater. Various natural and synthetic adsorbent such as chitosan, zeolite, barley waste, coconut shell carbon, activated carbon, citrus peel, bentonite/organo-clay and fly ash have been used to remove the heavy metals as well as oil and grease from wastewater [141].…”

“…These pollutants have serious damage to the biotic ecosystem of all organisms [1][2][3][4] . So these environmental pollutants can be treated in industrial waste water by using chemical, biologic and physical methods [5][6][7][8][9][10] . Adsorption is one of the most effective methods of physical and economic treatments.…”

A resin of 2-aminophenol-formaldehyde (2-A-Ph-F) was prepared and characterized by FT-IR technique. This resin was loaded on polystyrene (PS) as a matrices using DMF solvent, after that the polymer solution was used in electrospinning process in order to result electrospun nanofiber mat (2-A-Ph-F)/PS which has been used as adsorbent surface for studying the adsorption kinetic of malachite green dye (MG) at different temperatures to observe the behavior of this adsorption system. Generally, there is an increase in the values of rate constants with increasing temperature and the experimental results obeyed very well Lagergren's equation. So, the activation energy value (Ea) was estimated by Arrhenius equation, while the diffusion mechanism and the rate controlling steps explained according to Weber's intraparticle diffusion model.
