    Extraction of pharmaceuticals from hospital wastewater with eutectic solvents and terpenoids: computational, experimental, and simulation studies
    (Chemical Engineering Journal, 2022) Rodríguez Llorente, Diego; Hernández, Elisa; Gutiérrez Sánchez, Pablo; Navarro, Pablo; Águeda Maté, V. Ismael; Álvarez Torrellas, Silvia; García Rodríguez, Juan; Larriba Martínez, Marcos
    The presence of pharmaceuticals in wastewater, mainly in hospital wastewater, is a serious environmental concern, as they are not removed by conventional processes in wastewater treatment plants and are discharged into the natural environment. This work proposes extracting drugs from hospital wastewater using natural, renewable, and non-toxic solvents such as terpenes and eutectic solvents. First, molecular simulation has been used with the COSMO-RS method performing a massive screening of 43 terpenes, 11 eutectic solvents, and 5 conventional solvents with 31 common pharmaceuticals. The most promising solvents in the screening have been chosen to extract 11 pharmaceuticals simultaneously. Experimental tests with ultrapure water and real hospital wastewater matrices showed a strong influence of pH and matrix on extraction. Under the optimal conditions, global pharmaceutical extraction yields with carvacrol of 94.16 % and the eutectic solvent thymol+dodecanoic acid of 96.86 % were obtained. The regeneration and reuse of both solvents were studied in 5 consecutive stages, showing the carvacrol's high stability and regenerability. Using carvacrol, countercurrent extraction tests showed a fast mass transfer of pharmaceuticals and high extraction yields using low solvent-to-feed (S/F) ratios. The predictions obtained with COSMO-RS were similar to the experimental results, confirming the reliability of this method for selecting alternative solvents for the extraction of pharmaceuticals. Finally, the drug removal process was simulated in a countercurrent extraction. The complete removal of pharmaceuticals from hospital wastewater could be achieved using carvacrol with an S/F of 2.00 at pH 4.00 in an extractor with six equilibrium stages.

    Novel approach for azole fungicides extraction from aqueous environments using terpenes and eutectic solvents
    (Journal of Environmental Chemical Engineering, 2023) Rodríguez Llorente, Diego; García Fernández de la Puente, Enrique; García Rodríguez, Juan; Larriba Martínez, Marcos
    The presence of azole fungicides in aquatic environments is a significant issue due to their toxicity and persistence related to a low removal of these compounds by conventional processes in wastewater treatment plants. A growing environmental public concern is reflected in the inclusion of these compounds in the 2020 and 2022 European Surface Water Watch Lists. Therefore, it is necessary to develop efficient processes that allow their removal sustainably. This work applies liquid-liquid extraction using terpenes as green solvents and terpene-based eutectic solvents to remove azole fungicides from aqueous streams imazalil, metconozale, penconazole, prochloraz, and tebuconazole. First, an initial screening was performed by molecular simulation using the COSMO-RS method. The selected solvents were applied in the individual extraction of azole fungicides, and selecting the solvents thymol+octanoic acid and carvacrol. These solvents have been tested in studies with surface water matrix on the effect of temperature, initial concentration, and pH on extraction performance. From these results, it has been shown that carvacrol is the solvent that is least affected by these variables and obtains extraction yields higher than 97.88%, with a Solvent/Feed ratio up to 0.050, outperforming the conventional solvent methyl isobutyl ketone. This solvent has been used in solvent reuse cycles obtaining a reduction of less than 1% in three extraction cycles. Therefore, carvacrol is presented as a sustainable solvent for the extraction of azole fungicides from aqueous environments.

    Sustainable recovery of phenolic antioxidants from real olive vegetation water with natural hydrophobic eutectic solvents and terpenoids
    (Environmental Research, 2023) Rodríguez Llorente, Diego; Martín Gutiérrez, Diego; Suárez Rodríguez, Pablo; Navarro Tejedor, Pablo; Álvarez Torrellas, Silvia; García Rodríguez, Juan; Larriba Martínez, Marcos
    Olive oil production leads to the generation of olive mill wastewater (OMWW). Due to the presence of phenolic compounds, they are difficult to process, but they represent a source of high-added value chemicals since they have antioxidant and therapeutic properties. This work has studied the extraction of phenolic compounds from a type of OMWW, olive vegetation water, which presents these compounds in a more diluted dosage than in other studied to date, to revalue this waste stream. A real olive vegetation water from a Spanish olive oil producer was used, and liquid-liquid extraction was applied. Terpenoids and terpene-based hydrophobic eutectic solvents were systematically used to extract phenolic compounds following the concentrations of tyrosol, catechol, caffeic acid, and total phenolic content. By molecular simulation with the COSMO-RS method, 4 terpenoids, and 2 eutectic solvents were selected and compared with 2 conventional solvents. The Solvent/Feed ratio in the extraction of phenolic compounds was studied, showing that the solvents with the highest extraction results were geraniol, eucalyptol, and eutectic solvent menthol + camphor, which outperformed conventional solvents methyl isobutyl ketone and diisopropyl ether. Menthol + camphor gave total phenol extraction yields of 88.73% at a Solvent/Feed ratio in volume of 0.50, surpassing all solvents tested. A solvent reuse and regeneration process was applied by back-extraction of the 4 solvents: FTIR results showed the stability of the solvents while maintaining yields in the solvent reuse process. The phenolic compounds could be concentrated in the alkaline phase to factors up to 49.3 to the initial concentration in olive vegetation water. The alkaline phases were neutralized to obtain a precipitate with a caffeic acid content of up to 26 % wt%, and a tyrosol-rich supernatant with a concentration of up to 6.54 g/L. This work proposes a process using natural solvents to extract phenolic compounds from olive vegetation water.

    La pandemia provocada por el virus SARS-CoV-2 ha puesto de manifiesto la imperiosa necesidad de construir una sociedad basada en el conocimiento. Otros grandes retos sociales como son revertir el cambio climático y la conservación y/o recuperación del entorno natural hacen énfasis en la necesidad de un desarrollo sostenible e igualitario. En este sentido es necesario concienciar a las nuevas generaciones del papel primordial que deben jugar las ingenieras e ingenieros en el desarrollo futuro como motores de ese cambio necesario. Sin embargo, el número de estudiantes de ingenierías disminuye paulatinamente, siendo además profesiones copadas mayoritariamente por hombres. En el presente proyecto se plantea ir a colegios e institutos de la Comunidad de Madrid a realizar actividades que pongan de manifiesto lo que la ingeniería puede hacer por la sociedad, presentado por los y las estudiantes de ingeniería química de la UCM que servirán de referentes tanto femeninos como masculinos para las generaciones venideras.

    Extraction of antibiotics identified in the EU Watch List 2020 from hospital wastewater using hydrophobic eutectic solvents and terpenoids
    (Separation and Purification Technology, 2022) Gutiérrez Sánchez, Pablo; Rodríguez Llorente, Diego; Navarro, Pablo; Águeda Maté, Vicente Ismael; Álvarez Torrellas, Silvia; García, Juan; Larriba Martínez, Marcos
    The increasing consumption of pharmaceuticals, along with the ineffectiveness of conventional wastewater treatment, has resulted in an increased presence of these pollutants in both drinking water supplies and aquatic environments. The potential adverse health effects and environmental impact of these chemicals are drawing the attention of several bodies around the world. For instance, some antibiotics such as ciprofloxacin, trimethoprim, and sulfamethoxazole have been included in the most recent European Surface Water Watch List under the EU Water Framework Directive (Decision 2020/1161). The present work proposes the use of terpenoids and eutectic solvents, as effective and green solvents with low toxicity, for multicomponent liquid-liquid extraction of ciprofloxacin, trimethoprim, and sulfamethoxazole from ultrapure water and hospital wastewater. The COSMO-RS method was used for a predictive initial solvent screening. Thymol, carvacrol, eutectic solvents (thymol + fatty acids), and conventional solvents (methyl isobutyl ketone and ethyl acetate) were selected to be used in the experiments. The influence of the volume S/F ratio, aqueous matrix, and pH was analysed. Conventional solvents show significantly lower overall extraction yields than those observed for eutectic solvents and terpenoids at any pH and matrix. Carvacrol presented the most favourable conditions, reaching overall extraction yields above 98.0% (98.9% for trimethoprim, 99.5% for ciprofloxacin, and 97.0% for sulfamethoxazole) with hospital wastewater at pH 5.0 and S/F ratio of 1.00. Carvacrol showed a feasible operating in a continuous extraction column at room temperature, providing effective reuse and regeneration processes in this study.The increasing consumption of pharmaceuticals, along with the ineffectiveness of conventional wastewater treatment, has resulted in an increased presence of these pollutants in both drinking water supplies and aquatic environments.
