“…The correlation coefficient value (r 2 N 0.99) on AC (Table 7b) indicated that the Langmuir isotherm was the best fit and the constant (b L ) increased in the order: dimetroimidazole N metronidazole N ronidazole N tinidazole, which might be related to the decreased solubility of these nitroimidazoles in water with increasing absorption energy (Rivera-Utrilla et al, 2009). Sulfamethoxazole adsorption on waste based AC was found to be best matched with the Freundlich isotherm (r 2 = 0.987) with K F value of 0.308 ± 0.008 L n mmol 1 − n /kg (Calisto et al, 2015). For the adsorption of tetracycline on NH 4 -Cl induced AC (Table 7a), isotherm models of the Langmuir, Freundlich and Temkin also provided a good fit to the experimental data (Martins et al, 2015).…”

“…The equilibrium contact time was found to be 8 d to reach for the adsorptive removal of imidazoles when using 0.1 mg/L of AC (Rivera-Utrilla et al, 2009). On the other hand, the equilibrium contact time of sulfamethoxazole adsorption on waste based carbon was found to be significantly faster at 15 to 30 min (Table 7a) (Calisto et al, 2015). It was also mentioned that the experimental data was best described by pseudo second order with a r 2 value of 0.991, and maximum adsorption capacity (q max ) was found to be 118 mg/g.…”

Antibiotics as emerging contaminants are of global concern due to the development of antibiotic resistant genes potentially causing superbugs. Current wastewater treatment technology cannot sufficiently remove antibiotics from sewage, hence new and low-cost technology is needed. Adsorptive materials have been extensively used for the conditioning, remediation and removal of inorganic and organic hazardous materials, although their application for removing antibiotics has been reported for ~30 out of 250 antibiotics so far. The literature on the adsorptive removal of antibiotics using different adsorptive materials is summarized and critically reviewed, by comparing different adsorbents with varying physicochemical characteristics. The efficiency for removing antibiotics from water and wastewater by different adsorbents has been evaluated by examining their adsorption coefficient (Kd) values. For sulfamethoxazole the different adsorbents followed the trend: biochar (BC)> multi-walled carbon nanotubes (MWCNTs)>graphite = clay minerals, and for tetracycline the adsorptive materials followed the trend: SWCNT > graphite > MWCNT = activated carbon (AC) > bentonite = humic substance = clay minerals. The underlying controlling parameters for the adsorption technology have been examined. In addition, the cost of preparing adsorbents has been estimated, which followed the order of BCs < ACs < ion exchange resins < MWCNTs < SWCNTs. The future research challenges on process integration, production and modification of low-cost adsorbents are elaborated.

“…In this context, amongst the several advanced treatments proposed in the literature, adsorption is considered to be an interesting option due its versatility, efficiency, non-generation of transformation by-products and easiness of implementation when compared with other advanced treatments (Gupta and Saleh, 2013;Margot et al, 2013;Nam et al, 2014;Yu et al ., 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 4 expensive and have with high regeneration costs. These drawbacks have motivated the search for alternative adsorbents, including materials produced from agricultural and industrial wastes (Bhatnagar and Sillanpää, 2010;Calisto et al, 2015;Fernandez et al, 2015;Ferreira et al, 2015;Ioannidou and Zabaniotou, 2007;Mohan et al, 2014). Such an option also constitutes a new route for the management and economic valorization of these residues, simultaneously offering starting materials at low or no cost, which is the main concept behind circular economy (European Comission, 2014).…”

This work describes the adsorptive removal of three widely consumed psychiatric pharmaceuticals (carbamazepine, paroxetine and oxazepam) from ultrapure water. Two different adsorbents were used: a commercial activated carbon and a non-activated waste-based carbon (PS800-150-HCl), produced by pyrolysis of primary paper mill sludge. These adsorbents were used in single, binary and ternary batch experiments in order to determine the adsorption kinetics and equilibrium isotherms of the considered pharmaceuticals. For the three drugs and both carbons, the equilibrium was quickly attained (with maximum equilibrium times of 15 and 120 min for the waste-based and the commercial carbons, respectively) even in binary and ternary systems. Single component equilibrium data were adequately described by the Langmuir model, with the commercial carbon registering higher maximum adsorption capacities (between 272 ± 10 and 493 ± 12 μmol g) than PS800-150-HCl (between 64 ± 2 and 74 ± 1 μmol g). Multi-component equilibrium data were also best fitted by the single component Langmuir isotherm, followed by the Langmuir competitive model. Overall, competitive effects did not largely affect the performance of both adsorbents. Binary and ternary systems maintained fast kinetics, the individual maximum adsorption capacities were not lower than half of the single component systems and both carbons presented improved total adsorption capacities for multi-component solutions.

This work describes the removal of three pharmaceuticals, namely ceftriaxone sodium (CFX), diclofenac sodium (DCF) and atenolol (ATN) from water using magnetic poly (styrene-2-acrylamido-2-methyl propanesulfonic acid) (St-AMPS) adsorbent. This adsorbent was characterized by several techniques such as FTIR, TEM, TGA, VSM and DLS. Three kinetic models, pseudo-first-order, pseudo-secondorder and intra-particle diffusion models were used to study the adsorption kinetics.The results showed that the adsorption kinetics of pharmaceuticals onto magnetic poly (St-AMPS) adsorbent followed the pseudo-second-order model and were relatively rapid. In addition, it was found that the intra-particle diffusion was not the sole rate-controlling step and the adsorption of pharmaceuticals onto adsorbent occurred via two steps adsorption process. The experimental data were fitted with three isotherm models including Freundlich, Langmuir and Dubinin-Radushkevich (D-R). It was found that the adsorption of pharmaceuticals onto magnetic poly (St-AMPS) nanoparticles was the best described by the Langmuir model. Maximum adsorption capacities of 150.602, 47.824 and 119.904 mg/g were obtained for DCF, ATN and CFX, respectively. Also the obtained free energy from D-R isotherm (6.19, 4.93 and 6.45 kJ/mol for DCF, ATN and CFX respectively) indicated that the adsorption process was a physiosorption. Magnetic poly (St-AMPS) adsorbent could be recycled for removal of CFX, DCF and ATN by alkaline aqueous solution (pH 8). Therefore, this adsorbent can act as a promising adsorbent for water treatment processes.
