“…The peaks at wavenumbers of 1,114 and 1,400 cm −1 are attributed to alcoholic C-O and C-N stretching, respectively (Pan et al, 2018). The strong peak at 1,630 cm −1 is assigned to ether the aromatic stretching of C-C groups or the stretching of C=O, while the peaks at wavenumbers 2,923 and 2,854 cm −1 are due to the stretching vibrations of C-H groups (Liu et al, 2012;Ahsan et al, 2018;Pan et al, 2018). The broad band at 3,438 cm −1 could be assigned to the overlapping of -OH and -NH stretching (Pan et al, 2018;de Jesus et al, 2019).…”

“…Figure 2C presents that increasing biochar dosage from 1.5 to 2.5 g/L greatly improves removal efficiency from 44.2 to 62.3%, while further increasing biochar dosage to 3.5 g/L only slightly improves removal efficiency to 67.6%. This improvement can be attributed to the more adsorption sites from the enlarged surface area of adsorbent at a larger dosage level (Ahsan et al, 2018;Alidadi et al, 2018). The slow increase of removal efficiency after 2.5 g/L may be due to the agglomeration of biochar particles that reduces the total effective surface area and thereby reduces total sorption sites (Ahsan et al, 2018;Alidadi et al, 2018).…”

“…The removal efficiency slowly reduced from 44.2 to 27.6% with TC initial concentration growing from 30 to 60 ppm. This could be attributed to the restriction of the adsorption process at a high antibiotic loading level caused by the limited number of effective adsorption sites (Marzbali et al, 2016;Ahsan et al, 2018;Alidadi et al, 2018). The alleviated negative effect of initial TC concentration on the removal efficiency at high concentrations (20-60 ppm) may come from the increased TC concentration gradients between liquid phase and solid surfaces (Ahsan et al, 2018;Alidadi et al, 2018).…”

“…Solution pH is also an important parameter to consider for the effective adsorption process, which affects the properties of both adsorbents and pollutants (Liu et al, 2012;Marzbali et al, 2016;Ahsan et al, 2018;Alidadi et al, 2018;Jang et al, 2018;Selmi et al, 2018;Jang and Kan, 2019;Nguyen et al, 2019;Premarathna et al, 2019). The pH PZC of BC800 was 8.27 (see Figure 3A), which is relatively high.…”

In this study, biochars derived from waste fiberboard biomass were applied in tetracycline (TC) removal in aqueous solution. Biochar samples were prepared by slow pyrolysis at 300, 500, and 800 • C, and were characterized by ultimate analysis, Fourier transform infrared (FTIR), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET), etc. The effects of ionic strength (0-1.0 mol/L of NaCl), initial TC concentration (2.5-60 ppm), biochar dosage (1.5-2.5 g/L), and initial pH (2-10) were systemically determined. The results present that biochar prepared at 800 • C (BC800) generally possesses the highest aromatization degree and surface area with abundant pyridinic N (N-6) and accordingly shows a better removal efficiency (68.6%) than the other two biochar samples. Adsorption isotherm data were better fitted by the Freundlich model (R 2 is 0.94) than the Langmuir model (R 2 is 0.85). Thermodynamic study showed that the adsorption process is endothermic and mainly physical in nature with the values of H 0 being 48.0 kJ/mol, S 0 being 157.1 J/mol/K, and G 0 varying from 1.02 to −2.14 kJ/mol. The graphite-like structure in biochar enables the π-π interactions with a ring structure in the TC molecule, which, together with the N-6 acting as electron donor, is the main driving force of the adsorption process.

“…However, these techniques give rise to organic decomposition products that can sometimes be toxic and tedious to characterize. Therefore, alternative techniques to remove BPA are being investigated nowadays, remarkably the use of adsorbents [9,[11][12][13][14][15][16][17][18][19][20].…”

In this work we present a rapid and easy method to remove the totality of bisphenol A from aqueous solutions using ionic liquid (IL). Dispersive liquid–liquid microextraction is employed. The IL 1-octyl-3-methylimidazolium bis((trifluoromethane)sulfonyl)imide ([C8C1im] [NTf2]) is formed in situ because of the mixture of 1-octyl-3-methylimidazolium chloride ([C8C1im]Cl) and lithium bis(trifluoromethanesulfonyl)imide (Li[NTf2]) aqueous solutions. A cloud of microdroplets of IL formed by the dispersion generated through the precursors metathesis reaction allows the rapid and total extraction of bisphenol A (BPA). After centrifugation, the formed IL phase is deposited at the bottom of the flask and the total amount of BPA is extracted in the sedimented phase. The volume of IL is very low, in the order of microliters, which enables us to remove all the BPA from the solution. The technique studied is highly efficient, cost-effective, and presents less environmental impact than other extraction techniques, thus becoming an outstanding alternative to the most commonly used methods. BPA concentration is determined by high performance liquid chromatography by injecting the IL phase directly. An extraction kinetic model for the kinetic profile has been tested for this method, which allows to infer the ideal experimental conditions to execute the extraction method.
