Evaluation of electrolytic reactor configuration for the regeneration of granular activated carbon saturated with methylene blue

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

“…These are undesirable properties as they lead to long adsorption and regeneration periods [32]. While carbon materials cost is relatively affordable, they suffer from saturation and surface damage, leading to material losses after subsequent cycles [29,33,34]. Alternatively, other studies have reported the use of non-porous materials with low surface area such as Nyex™.…”

Enhanced adsorption capacity of activated carbon over thermal oxidation treatment for methylene blue removal: kinetics, equilibrium, thermodynamic, and reusability studies

“… 13 In addition, the toxicity of the adsorbed dyes on the AC is a problem as these cannot decompose and reduce the toxicity. 14 The regeneration processes applied for the spent AC from MB adsorption includes electrochemical, 15 microwave, 16 high-temperature treatment under a special atmosphere (N 2 , 17 steam, 18 or CO 2 (ref. 19 )), and thermal oxidation treatment.…”
