“…The GCE/MWCNT sensor was applied in the analysis of three types of sample: artificial urine, since HCT and TRT are regulated and monitored by the World Anti-Doping Agency (WADA) [39], and in tap water and water treatment plant water, due to concerns about the release of these drugs and their presence in wastewater [40]. In all cases, the concentrations obtained were close to the fortified concentrations ( Table 3).…”

Hemodialysis is the most commonly used method for the treatment of chronic kidney disease. In this procedure, some patients use diuretics to control weight gain and blood pressure. In this work, a voltammetric sensor based on a glassy carbon electrode modified with carbon nanotubes (GCE/MWCNT) is described for the simultaneous determination of the diuretics hydrochlorothiazide (HCT) and triamterene (TRT). The oxidation of the diuretics on the GCE/MWCNT surface was observed at 1.01 and 1.17V for HCT and TRT, respectively, allowing simultaneous determination, which was not possible with the unmodified glassy carbon electrode. The GCE/MWCNT electrode provided 6-fold and 10-fold gains in anode peak intensity for HCT and TRT, respectively, compared to the unmodified electrode. After optimization of the conditions (pH, accumulation time, and accumulation potential), analytical curves were constructed for the analytes in the range from 1.0 × 10 to 2.0 × 10molL. The detection limits for HCT and TRT were 2.8 × 10 and 2.9 × 10molL, respectively. A high performance liquid chromatography method with diode array detection was also developed for the determination of HCT and TRT in hemodialysis samples, for comparison with the electroanalytical method.

“…In order to quickly determine ECs in WW, Campos‐Mañas et al used direct injection coupled with ultra‐high‐performance liquid chromatography quadrupole‐linear ion trap analyzer‐tandem mass spectrometry (LC‐QqLIT‐MS/MS). They reported that sample handling time and solvent consumption were significantly reduced by using direct injection and the developed optimized method to produce low LODs (1–357 ng/L), leading to the quantification of 67 ECs (10–26.7 mg/L) in real WW samples.…”

The scarcity of industrial and domestic use water has become an important issue as industrial operations and localized pollution have burgeoned over the last decade. Wastewater (WW) treatment for recycling and reuse is gaining importance as an alternate source of water supply to circumvent water shortages. Wastewater treatment requires thorough planning, design, construction, and management of treatment facilities in order to discharge the treated water to the aquatic environment or for recycling and reuse. One detrimental effect of growing populations and urbanization has been the release of many persistent emerging contaminants (ECs) to the environment, mainly detected in WW. The entry of these ECs to the aquatic environment through wastewater treatment plants (WWTPs) may cause different ecological risks such as reproductive toxicity, endocrine disruption, and microbial resistance. The quantification of ECs (in ng or pg level) in complex matrices, such as WW samples recognized through non-target screening approaches, has played a key role in the planning and design of water treatment facilities. The purpose of this review is to provide information about advancements in wastewater treatment technologies such as constructed wetland (CW) and advanced oxidation processes (AOPs) and the fate of emerging contaminants during these treatments. Further, this review also reports the ecological effects of these contaminants and their by-products formed during various advanced WW treatment processes. The review also discusses advancements in different analytical techniques for the analysis of ECs in WW.

“…The inefficient destruction of drugs and their metabolites in municipal wastewater treatments plants (WWTPs) using physicochemical and biological processes is a major cause of accumulation and persistence of such organic pollutants in the aquatic environment. [1][2][3] Great social alarm has been created by the presence of these compounds, even trace amounts, in water streams due to their potentially harmful effects on the entire ecosystem, particularly on humans and animals. [4,5] Hence, powerful oxidation processes must be developed to ensure their complete removal from wastewater.…”

“…Its most common primary metabolite is 4-aminoantipyrine (4-AA), which has been detected up to 27 μg L À 1 in sewage treatment systems. [2,3] 4-AA (C 11 H 13 N 3 O, M = 203.24 g mol À 1 ) is a N-heteroaromatic molecule with a 4-aminopyrazolone group bonded to a benzene ring. The beneficial biological activity of 4-AA has been demonstrated.…”

Assessment of 4‐Aminoantipyrine Degradation and Mineralization by Photoelectro‐Fenton with a Boron‐Doped Diamond Anode: Optimization, Treatment in Municipal Secondary Effluent, and Toxicity

a] 4-Aminoantipyrine (4-AA), a persistent metabolite of dipyrone found in natural water, has been treated in 100 mL of aqueous 0.050 M Na 2 SO 4 solutions at pH 3.0 by photoelectro-Fenton (PEF) with a 4 W UVA lamp. The assays were performed in a cell equipped with a boron-doped diamond (BDD) anode and an air-diffusion cathode for H 2 O 2 generation. The formation of an unstable Fe(III)-4-AA complex with 1 : 2 molar ratio was evidenced. A 2 4 central composite design was used to assess the effect of four independent variables on PEF performance.The optimized conditions for 62.5 mg L À 1 4-AA were: current density of 77.5 mA cm À 2 and 47.75 mg L À 1 Fe 2 + , yielding 99 % 4-AA degradation at 7 min, and 45 % 4-AA mineralization with 3.2 % mineralization current efficiency at 130 min. Slightly slower degradation and similar mineralization were obtained under these conditions when 4-AA was spiked into a municipal secondary effluent, showing a low influence of natural organic matter on PEF. The initially high acute toxicity determined using Artemia salina was largely diminished upon PEF treatment.
