“…Whereas, electrolytic combustion efficiencies of the PbO 2 electrode and Cu-PbO 2 electrode for the degradation reaction of amoxicillin were 65.6% and 98.4% [55]. Adsorption and biodegradation in the A/O-MBR system represented the 68% removal of amoxicillin antibiotic [56]. e natural montmorillonite clay pillared with titanium oxide depicted adsorptive removal of 4.26 mg/g for amoxicillin [57].…”

The industry is looking for new materials which can respond to specific applications that exclusively advance materials can provide. In this context, nanoparticles and nanocomposites opened an interesting method for designing specific properties which can be modulated according to the requirements. The preparation of biomolecules supported trimetallic nanoparticles and some other derives is a good example of the complex systems that can be designed for getting exclusive properties. This study is based on the preparation of new cyclodextrin supported Fe/La/Zn trimetallic nanocomposite by the microemulsion technique. Photocatalytic degradation of amoxicillin was performed using cyclodextrin-Fe/La/Zn. 78% of amoxicillin photodegradation along 4 hours of photoirradiation was achieved. Finally, the catalytic nature of new material was explored for oxidation and esterification reactions. The present study revealed that this advanced multifunctional nanomaterial can be successfully employed for environmental remediation and catalytic activities.

“…Although the focuses of this study were not to investigate the treatment of the pollutant, but its effect on the nitrification process, the results show that it is possible to remove the compound from the liquid phase at high concentrations, i.e., higher than that found in wastewater. In wastewater treatment systems, the main mechanisms of AMX removal are adsorption and these compounds are hardly biodegradable, the key to the efficiency of the process being the solid retention time (SRT) and the hydraulic retention time (HRT) [22,34,35].…”

“…Recent studies [18][19][20][21][22] show the toxic effects related to the presence of antibiotics both in the environment and in effluents, however, they are still limited, having studied the effects of few antibiotics, and also few studies address the nitrification process, an essential step in the treatment of effluents for nitrogen removal [23]. The chronic impact of tetracycline on biomass with enriched nitrifying community sustained in a lab-scale activated sludge system was evaluated.…”

Amoxicillin (AMX) is one of the most widely used antibiotics in the world and its presence in wastewater is of great concern for its potential to bacteria selection. However, there is still a gap about the toxicity effect of AMX in nitrifier biomass from activated sludge (AS). This study is based on the implementation of respirometric tests in batches in order to evaluate the toxic effluent toxicity in the nitrification process of AS. The tests were conducted by comparing respiration rates with effluent containing ammonia nitrogen (NH 4 + -N) and nitrite nitrogen (NO 2 − -N) called "reference" and batches containing toxic effluent doped with different concentrations of AMX here called "process." Results with effluent containing concentrations greater than 100 mg L −1 showed that AMX negatively affected the specific growth rate (μ m ) of ammonia-oxidizing bacteria (AOB) (from 0.50 d −1 to 0.13 d −1 ) and nitrite-oxidizing bacteria (NOB) (from 0.64 d −1 to 0.15 d −1 ). Although there is no total inhibition of populations, these μ m values are limiting for a feasible development of the nitrification process in AS systems. The removal of AMX decreased from 99 to 37% (liquid phase) when the concentration of AMX increased (20 mg L −1 to 200 mg L −1 ). A decrease in the microbial community AOB and NOB was observed through fluorescent in situ hybridization (FISH), corroborating the results of respirometry. In summary, the study showed that the inhibition of the AS nitrification process occurs in the presence of high concentrations of AMX and the most susceptible group are the NOB.

“…In the last dictate, the removal of chemical, biochemical, and biological pollutants (heavy metals, dyes, and pharmaceutical products…) from natural aquatic mediums became a necessary operation to save the environment. The great dispersal of these hazards related directly to the fast growth of the manufacturing activities in our cities [1,2] . Pharmaceutical pollution becomes an inevitable environmental problem of emerging concern; these kinds of compounds are persistent and they have incompletely degraded in sewage treatment stations [3][4][5] due to their resistance to biodegradation [6] and persistence in aquatic ecosystems.…”

This study is focused on the removal of Dextropropoxyphene (DPP) and Paracetamol (PAR) from aqueous solutions by sorption on Luffa Cylindrica fibres, as a low-cost biosorbent, that was initially characterized using BET, FTIR spectroscopy, and SEM analysis. The sorption study has been realized by the batch method with the effect of the biosorbent amount, initial concentration, solution pH and batch temperature. The modelling of the sorption phenomenon was based on the mathematical approach of the modified Redlich-Peterson isotherm equation (RP), where the dimensionless form of this isotherm, corresponding to the optimal curve, allows the α parameter evaluation. The same value of α was obtained for both pharmaceutical compounds, while the values where 2 and 10 for DPP and PAR, respectively. The linear regression of the Redlich-Peterson isotherm equation was also confirmed by analysis of variance (ANOVA). The obtained results show that p-value is less than 0.05, with correlation coefficients (Radj2) equal to 0.9515 and 0.9283 for DPP and PAR, respectively. The kinetics modelling shows that the sorption mechanism obeys the pseudo-second-order and intraparticular diffusion. The adsorption process is exothermic, spontaneous and the molecules of the two pharmaceutical products have a random behaviour on the Luffa Cylindrica active sites.
