Pharmaceutical active compounds (PhACs) are some of the most recalcitrant water pollutants causing undesired environmental and human effects. In absence of adapted decontamination technologies, there is an urgent need to develop efficient and sustainable alternatives for water remediation. Metal–organic frameworks (MOFs) have recently emerged as promising candidates for adsorbing contaminants as well as providing photoactive sites, as they possess exceptional porosity and chemical versatility. To date, the reported studies using MOFs in water remediation have been mainly focused on the removal of a single type of PhACs and rarely on the combined elimination of PhACs mixtures. Herein, the eco-friendly bismuth-based MOF, SU-101, has been originally proposed as an efficient adsorbent-photocatalyst for the elimination of a mixture of three challenging persistent PhACs, frequently detected in wastewater and surface water in ng L−1 to mg·L−1 concentrations: the antibiotic sulfamethazine (SMT), the anti-inflammatory diclofenac (DCF), and the antihypertensive atenolol (At). Adsorption experiments of the mixture revealed that SU-101 exhibited a great adsorption capacity towards At, resulting in an almost complete removal (94.1 ± 0.8% for combined adsorption) in only 5 h. Also, SU-101 demonstrated a remarkable photocatalytic activity under visible light to simultaneously degrade DCF and SMT (99.6 ± 0.4% and 89.2 ± 1.4%, respectively). In addition, MOF-contaminant interactions, the photocatalytic mechanism and degradation pathways were investigated, also assessing the toxicity of the resulting degradation products. Even further, recycling and regeneration studies were performed, demonstrating its efficient reuse for 4 consecutive cycles without further treatment, and its subsequent successful regeneration by simply washing the material with a NaCl solution.

Emerging contaminants, such as atenolol, in water environments are a reality that cannot be avoided. One of the alternatives to alleviating this situation is using materials capable of removing these compounds from water by adsorption. Many materials have proven efficient, and carbon nanomaterials can be emphasized. A gap in these studies is the comparison of different dimensions of the materials because carbon nanomaterials can be obtained in 0, 1, 2, or 3 dimensions. In this context, the present work aims to unravel the differences in the ability to absorb atenolol in carbon nanomaterials with different dimensions and degrees of oxidation: multiwalled carbon nanotubes, oxidized or not, reduced graphene oxide, and three-dimensional reduced graphene oxide with different degrees of oxidation. Experiments were performed to evaluate the kinetic and isothermal performance of the materials as well as their reuse. In addressing the abstract graphic: yes, both the dimensionality and the degree of oxidation influence the adsorption of the drug. The results showed that the sorptive capacity tends to increase with the increase in the dimensionality and with the degree of oxidation of the structures. Thus, the more oxidized three-dimensional reduced graphene oxide showed excellent interaction with atenolol, with a high sorptive capacity that can be quickly obtained. This better sorption capacity results from its oxidized structure and morphology with noncompacted cavities. Finally, the reuse study also showed excellent results for the same nanomaterial, underlining its performance in the present study. Thus, this tridimensional material is an efficient alternative for removing atenolol from aqueous environments and can be efficiently applied in water treatment.
