“…It is well known that the SMX form depends greatly on the pH of the medium 447 (Hou et al, 2013;Qi et al, 2014). Given the two pKa values of SMX, for pH around 4, 448 the non-protonated form is the predominant one, increasing pH to 7, most of the SMX 449 molecules will be present in the deprotonated state and for a pH > 7, the predominant 450 form of SMX will be the deprotonated one by the complete dissociation of the hydrogen 451 present in the -NHgroup (Qi et al, 2014).…”

43A waste-based alternative activated carbon (AAC) was produced from paper mill sludge 44 under optimized conditions. Aiming its application in tertiary wastewater treatment, 45 AAC was used for the removal of carbamazepine, sulfamethoxazole and paroxetine 46 from biologically treated municipal wastewater. Kinetic and equilibrium adsorption 47 experiments were run under batch operation conditions. For comparison purposes, they 48 were also performed in ultrapure water and using a high-performance commercial AC 49 (CAC). Adsorption kinetics was fast for the three pharmaceuticals and similar onto 50 AAC and CAC in either wastewater or ultrapure water. However, matrix effects were 51 observed in the equilibrium results, being more remarkable for AAC. These effects were 52 evidenced by Langmuir maximum adsorption capacities (qm, mg g -1 ): for AAC, the 53 lowest and highest qm were 194 ± 10 (SMX) and 287 ± 9 (PAR), in ultrapure water, and 54 47 ± 1 (SMX) and 407 ± 14 (PAR), in wastewater; while for CAC, the lowest and 55 highest qm were 118 ± 7 (SMX) and 190 ± 16 (PAR) in ultrapure water, and 123 ± 5 56 (SMX) and 160 ± 7 (CBZ) in wastewater. It was found that the matrix pH played a key 57 role in these differences by controlling the surface electrostatic interactions between 58 pharmaceutical and AC. Overall, it was evidenced the need of adsorption results in real 59 matrices and demonstrated that AAC is a promising option to be implemented in tertiary 60 wastewater treatments for pharmaceuticals' removal. 61 62 63 64 65 66 67 68 69

Background: The limitless presence of pharmaceutical contaminants in discharged wastewater has emerged as a threat to aquatic species and humans. Their presence in drinking water has although raised substantial concerns, very little is known about the fate and ecological impacts of these pollutants. As a result, these pollutants are inevitably introduced to our food chain at trace concentrations. Unfortunately, the conventional wastewater treatment techniques are unable to treat pharmaceuticals completely with practical limitations. The focus has now been shifted towards nanotechnology for the successful remediation of these persistent pollutants. Thus, the current review specifically focuses on providing readers brief yet sharp insights into applications of various nanomaterials for the removal of pharmaceutical contaminants. Methods: An exhaustive collection of bibliographic database was done with articles having high impact and citations in relevant research domains. An in-depth analysis of screened papers was done through standard tools. Studies were categorized according to the use of nanoscale materials as nano-adsorbents (graphene, carbon nanotubes), nanophotocatalysts (metal, metal oxide), nano-filtration, and ozonation for promising alternative technologies for the efficient removal of recalcitrant contaminants. Results: A total of 365 research articles were selected. The contemporary advancements in the field of nanomaterials for drinking and wastewater treatment have been thoroughly analyzed along with their future perspectives. Conclusion: The recommendations provided in this article will be useful to adopt novel strategies for on-site removal of the emerging contaminants in pharmaceutical effluents and related industries.
