“…The adsorption of almost 50% of total phenols is in agreement with several studies in the literature that confirm the efficiency of the adsorption of phenolic compounds in activated charcoal (RENGARAJ et al, 2002;DUAN et al, 2015;XIONG et al, 2018). It has been (AHMARUZZAMAN; SHARMA, 2005) that the adsorption of phenols on an amphoteric surface (such as the activated charcoal of this study) from an aqueous solution depends on two factors: the dissociation of the electrolytes in the solution and the dominant charge on the activated charcoal surface.…”

This work aimed to integrate two wastewater treatment technologies, Fenton process as the primary treatment and adsorption aiming achieve maximum removal efficiency and adequation to the environmental and water legislations. Wastewater from a cosmetics industry plant in the metropolitan area of Goiânia (Brazil) was the object of this research. It was analysed environmental parameters as absorbance, total iron, chemical oxygen demand, pH, total phenols, conductivity, H2O2, dissolved oxygen, turbidity, and total solids. They were analyzed in between processes at all stages. The effects of Fe2+ (18.42-257.89 mg L-1) and H2O2 (500-2300 mg L-1) concentrations and pH values (3.00-5.50) were studied for the Fenton process treatment. In adsorption, the activated carbon was characterized by infrared spectroscopy, elemental analysis, adsorption and desorption of N2 and thermogravimetry (TG/DTA). The effect of the contact time (4min-24h) and of the temperature variation in the system 20-60 °C were studied. By integrating the two technologies, a satisfactory removal rate was achieved for the analyzed parameters in the total time of treatment of 82 minutes

“…Significantly, human poisoning of phenol is mainly caused by contacting with respiratory tract and skin . The low concentration can induce protein denaturation, and the high concentration causes protein precipitation, thereby leading to a direct damage to cells and paralysis of central nervous system . Effective removal of phenol has been a significant issue in energy application and environmental protection.…”

Activated carbons are synthesized from rice husk by one‐ and two‐step pyrolysis. In general, two‐step pyrolysis produces a higher yield of activated carbons. The yield of activated carbon decreases with the increase of mass ratio of KOH and biomass, which has a significant impact on the development of surface area and porosity. The maximum S BET (2138 m 2 g −1 ) is achieved with micro‐ and mesoporous structures, which is favored for the adsorption process. The activated carbons can efficiently remove phenol from water by a few minutes. In particular, the maximum adsorption capacity (201 mg g −1 ) is achieved due to the excellent surface textural properties. The Langmuir model can better define the adsorption isotherm. The high correlation coefficient value ( R 2 = 0.9991) indicates a monolayer adsorption behavior. The adsorption process can be well‐fitted by the pseudo‐second‐order model. Herein, the phenol molecules pass into the internal surface via liquid‐film‐controlled diffusion, so the behavior of phenol adsorption onto activated carbons is mainly controlled via chemisorption. In addition, the functional groups on the outer surfaces of activated carbons can attract the phenol molecules onto their internal surface via the “π–π dispersion interaction” and “donor–acceptor effect.”

Nanoporous carbon materials have been widely utilized for myriad applications owing to their intriguing physicochemical properties. Development of green and clean synthetic techniques/procedures to generate nanoporous carbon materials especially derived from inexpensive waste precursors/resources has rejuvenated the chemistry of carbon materials owing to the abundant nature and low cost of these sources and their ability to generate unique surface/porous structures. These nanoporous carbon materials have been heavily explored in multiple sectors such as soil/water remediation, adsorption and separation, catalysis, energy storage/conversion, capture and conversion of carbon dioxide. In this topical review, the recent state‐of‐the‐art research progress achieved in the design and development of waste‐derived advanced functionalized porous carbon materials are summarized. The various lab‐specific approaches and methodologies involved in synthesizing these materials are discussed in detail. In addition, the potential applications of waste‐derived functionalized porous carbons in the fields of environment, energy storage, and conversion applications are highlighted. Finally, a discussion on a few suggestions for future research is concluded. It is believed that this review provide inspiration for many new research activities over a wide range of disciplines.
