“…[100][101][102] Conversely, the isotherm study revealed that the Elovich model could best describe the equilibrium data, and the ndings also demonstrated that the adsorption operation followed the LI and FI models. 108 The maximum adsorption efficiency (∼98%) observed by 108 is comparable to the one (99%) reported for EE2 by 109 using mesoporous carbons and another one (99%) reported by Tagliavini et al 110 for the adsorption of E2 in cellulose ultraltration membrane setup coupled with polymer-based spherical AC produced by carbonization and steam activation of cross-linked polystyrene. However, the efficiency is higher than the one (50%) reported by 111 using walnut shell BC and the one (<95%) reported by 112,113 using cellulose nanoltration and ultraltration membranes setup coupled with polymer-based spherical AC.…”

“…Electrostatic attraction or repulsion of a certain ionic or ionizable substance, e.g., by carboxylic acid groups of the AC, depends on the pK a value(s) of the substance as well as the pH value of the solution and dissolved ions (e.g., Ca 2+ ) (Kah et al 2017). Hydrogen bonding occurs between all kind of SOGs and respective functional groups of the adsorbate molecule (Tagliavini et al 2020). Electron donor-acceptor mechanisms can be established by carbonyl groups, but in light of the aromatic carbon structure of AC, this may not be a key mechanism for aromatic moieties of the adsorbate (Franz et al 2000).…”

“…However, SOGs also influence dispersive interaction by altering the electron density in graphene -electron orbitals (Moreno-Castilla 2004), e.g., carboxylic acids decrease the electron density by a negative inductive effect, while phenol and lactone groups increase the electron density by positive mesomeric effects. It has been reported that, for example, phenol groups of AC can chemically react with amide moieties of OMP molecules (Nielsen et al 2014) and that carbonyl groups influence the adsorption of estradiol (Tagliavini et al 2020). However, the quantification of SOGs as a relevant material property is rarely applied to commercially available ACs.…”

Characterization of activated carbons for water treatment using TGA-FTIR for analysis of oxygen-containing functional groups

Water treatment with activated carbon (AC) is an established method for the removal of organic micropollutants and natural organic matter. However, it is not yet possible to predict the removal of individual pollutants. An appropriate material characterization, matching adsorption processes in water, might be the missing piece in the puzzle. To this end, this study examined 25 different commercially available ACs to evaluate their material properties. Frequently reported analyses, including N$$_2$$ 2 adsorption/desorption, CHNS(O), point of zero charge (PZC) analysis, and X-ray photoelectron spectroscopy, were conducted on a selected subset of powdered ACs. Inorganic elements examined using X-ray fluorescence and X-ray diffraction spectroscopy revealed that relative elemental contents were distinctive to the individual AC’s raw material and activation procedure. This study also is the first to use thermogravimetric analysis (TGA) coupled to Fourier-transform infrared spectroscopy (FTIR) to conduct quantitative analyses of functional surface oxygen groups (SOGs: carboxylic acid, anhydride, lactone, phenol, carbonyl, and pyrone groups) on such a large number of ACs. The comparably economical TGA method was found to provide good surrogates for the PZC by pyrolytic mass loss up to 600 $$^{\circ }$$ ∘ C (ML$$_{600}$$ 600 ), for the oxygen content by ML$$_{1000}$$ 1000 and for the carbon content by oxidation. Mass loss profiles depict the AC’s chemistry like fingerprints. Furthermore, we found that SOG contents determined by TGA-FTIR covered a wide individual range and depended on the raw material and production process of the AC. TGA and TGA-FTIR might therefore be used to identify the suitability of a particular AC for a variety of target substances in different target waters. This can help practitioners to control AC use in waterworks or wastewater treatment plants.

“…Indeed, existing wastewater treatment plants (WWTPs) are not designed to efficiently and completely eliminate these organic pollutants [4,16]. Thus, several technologies have been developed to remove micropollutants from water and wastewater, e.g., adsorption by activated carbon [17][18][19], ozonation [20,21], and advanced oxidation processes (AOPs) have been developed to remove micropollutants from water and wastewater. AOPs are treatment technologies that involve the generation of highly reactive species, such as hydroxyl radicals, to degrade micropollutants.…”

Many approaches have been investigated to eliminate pharmaceuticals in wastewater treatment plants during the last decades. However, a lack of sustainable and efficient solutions exists for the removal of hormones by advanced oxidation processes. The aim of this study was to synthesize and test new photoactive bio composites for the elimination of these molecules in wastewater effluents. The new materials were obtained from the activated carbon (AC) of Arganian spinosa tree nutshells and titanium tetrachloride by the sol gel method. SEM analysis allowed one to confirm the formation of TiO2 particles homogeneously dispersed at the surface of AC with a controlled titanium dioxide mass ratio, a specific TiO2 anatase structure, and a highly specific surface area, evidenced by ATG, XRD, and BET analysis, respectively. The obtained composites were revealed to quantitatively absorb carbamazepine (CBZ), which is used as a referred pharmaceutical, and leading to its total elimination after 40 min under irradiation with the most effective material. TiO2 high content disfavors CBZ adsorption but improves its degradation. In the presence of the composite, three hormones (17α-ethinylestradiol, estrone, and β-estradiol) are partially adsorbed onto the composite and totally degraded after 60 min under UV light exposure. This study constitutes a promising solution for the efficient treatment of wastewater contaminated by hormones.
