    Abstract Due to the negative effects of emerging contaminants on the environment, that can potentially induce deleterious effects in aquatic and human life, this paper focuses on the removal from the water of Furosemide, through the adsorption process. Indeed, only a few papers are available in the literature about the Furosemide adsorption and, chitosan films are thus proposed for this purpose as safe, sustainable, and recyclable adsorbent materials. In the present work, the effects on the adsorption process of several experimental parameters such as the pH values, ionic strength, amount of adsorbent/pollutant, and temperature values were investigated. The kinetics models, isotherms of adsorption, and the thermodynamic parameters were studied showing that the Furosemide physisorption occurred on the heterogeneous Chitosan surface, endothermically (ΔH° = +31.27 ± 3.40 kJ mol⁻¹) and spontaneously (ΔS° = +150.00 ± 10.00 J mol⁻¹ K⁻¹), following a pseudo-second-order kinetic model. The 90% of the pollutant was adsorbed in 2 h, with a maximum adsorption capacity of 3.5 mg × g⁻¹. Despite these relatively low adsorption capacities, experiments of desorption were performed and 100% of adsorbed Furosemide was recovered by using concentrated NaCl solutions, proposing a low-cost and green approach, with respect to the previous literature relative to the Furosemide adsorption, fundamental for the pollutant recovery and adsorbent reuse.

    Abstract This paper focuses on the removal of tetracycline from polluted water by chitosan-olive pomace adsorbing films. More specifically, both raw olive solid wastes (olive pomace) and the olive solid wastes/chitosan composite were compared and used for this purpose. Adsorption capacities values of 16 mg × g−1 and 1.6 mg × g−1 were obtained for the two adsorbents respectively. However, chitosan/olive pomace is proposed as suitable for environmental applications avoiding the dispersion of the pomace blocked inside the chitosan film. To detail the adsorption process, the effect of several experimental parameters such as the pH values, ionic strength, amount of adsorbent and pollutant and temperature values was investigated. The results showed that the adsorption process improved increasing the pH values, with a maximum at pH 8, and it was negatively affected by the presence of salts that retarded the adsorption. Indeed, the desorption of tetracycline was obtained in a MgCl2 2 M solution. So, a low-cost and cleaner approach, fundamental for the pollutant recovery and for an adsorbent safe reuse, for several cycles of adsorption/desorption, transforming a waste in resource is presented. The kinetics, isotherms models of adsorption and the thermodynamic parameters (ΔG°, ΔH° and ΔS°) were also evaluated observing that the physisorption of the pollutant occurred with and an endothermic character (ΔH° > 0) with ΔG° < 0 and ΔS° > 0. The use of Advanced Oxidation Processes was proposed as possible alternative to the tetracycline recovery, obtaining its degradation after the desorption. With the present paper, the alternative reuse of olive pomace is reported avoiding its disposal in the environment claiming its potential in the removal/recover of emerging contaminants from water.

    Abstract In this work, the adsorption of atrazine, as emerging pollutant, from water, by using α-, β- and γ-cyclodextrin-epichlorohydrin water-insoluble copolymers, is presented and carefully investigated by using several complementary techniques. Various in batch experiments were performed, changing different parameters. The aqueous atrazine concentration were evaluated by HPLC analyses, and very interesting results were obtained when α-cyclodextrin-based polymer was employed. The presence of weak interactions, not affected by pH changes, involving H-bonds, van der Waals forces, with the possible formation of inclusions complexes host-guest-like between atrazine and the polymers were suggested and confirmed by FTIR-ATR spectroscopy and DSC analysis. Accordingly, the Freundlich isotherm well fitted the experimental data indicating the heterogeneous character of the adsorption process, better described by the pseudo-second order kinetic model. Overall, the thermodynamic analysis showed that the atrazine adsorption on α-, β- and γ-cyclodextrin-epichlorohydrin polymers was exothermic, exergonic occurring with an increase of entropy. Atrazine desorption experiments were carried out on α-EPI polymer through extraction with water, ethanol and methanol, indicating this latter as the most effective solvent for the purpose. Furthermore it was found that CD-EPI polymers can be effectively regenerated and reused at least for five times, thus promoting a circular economy.
