“…From the results obtained in our previous work, the composite sensor exhibited an excellent response for detecting HCQ in H 2 SO 4 /ultrapure water solution. However, the use of ultrapure water with a single target pollutant could mask the applicability of the experimental data to actual uses [20] with real water matrices (which are composed by several inorganic and organic compounds that can affect the electrochemical sensor response to quantify HCQ). Then, this composite sensor was used to construct an analytical curve with a non-polluted river water matrix (see Table 1).…”

“…Considering that several research groups are evaluating the treatment effectiveness of certain technologies by polluting in laboratory different water matrices (e.g., river, sea, groundwater, tap water, drinking water and so on) with a well-known amount of a single target pollutant for understanding the experimental data in order to translate to real applications [20]. Then, this work aims to electrochemically treat a real water matrix polluted with HCQ.…”

Hydroxychloroquine (HCQ) has been extensively consumed due to the Coronavirus (COVID-19) pandemic. Therefore, it is increasingly found in different water matrices. For this reason, the concentration of HCQ in water should be monitored and the treatment of contaminated water matrices with HCQ is a key issue to overcome immediately. Thus, in this study, the development of technologies and smart water solutions to reach the Sustainable Development Goal 6 (SDG6) is the main objective. To do that, the integration of electrochemical technologies for their environmental application on HCQ detection, quantification and degradation was performed. Firstly, an electrochemical cork-graphite sensor was prepared to identify/quantify HCQ in river water matrices by differential pulse voltammetric (DPV) method. Subsequently, an HCQ-polluted river water sample was electrochemically treated with BDD electrode by applying 15, 30 and 45 mA cm−2. The HCQ decay and organic matter removal was monitored by DPV with composite sensor and chemical oxygen demand (COD) measurements, respectively. Results clearly confirmed that, on the one hand, the cork-graphite sensor exhibited good current response to quantify of HCQ in the river water matrix, with limit of detection and quantification of 1.46 mg L−1 (≈3.36 µM) and 4.42 mg L−1 (≈10.19 µM), respectively. On the other hand, the electrochemical oxidation (EO) efficiently removed HCQ from real river water sample using BDD electrodes. Complete HCQ removal was achieved at all applied current densities; whereas in terms of COD, significant removals (68%, 71% and 84% at 15, 30 and 45 mA cm−2, respectively) were achieved. Based on the achieved results, the offline integration of electrochemical SDG6 technologies in order to monitor and remove HCQ is an efficient and effective strategy.

“…Another effective parameter on the electrochemical oxidation process of DCF is supported electrolyte so in the present study three doses of NaCl (0.1, 0.3 and 0.5 g NaCl) have been evaluated. Sodium chloride has good ionic strength and it exhibited very useful role in electrochemical degradation process of organic compounds compared to other electrolytes such as NaNO 3 , Na 2 SO 4 and Na 2 CO 3 (Brito et al 2021). Two different behaviors were observed for DCF elimination e ciency during the electrolysis process as depicted in Fig.…”

In electrochemical degradation process, the elimination of organic pollutants could be enhanced using supporting electrolyte and increasing applied voltage. After degradation of organic compound some by-products are formed. Chlorinated products are the main products generated in the presence of sodium chloride. In the present study, diclofenac (DCF) has been electrochemically treated using graphite as anode and sodium chloride (NaCl) as a supporting electrolyte. Monitoring the removal and elucidation the by-products were provided using HPLC and LC-TOF/MS, respectively. High removal% of 94% DCF was observed under conditions: 0.5 g NaCl, 5 volt and 80 min of electrolysis while chemical oxygen demand (COD) removal% was 88% under same conditions but 360 min of electrolysis. Pseudo-first order rate constant values were quite varied based on the selected experimental conditions; the ranges of rate constants were 0.0062–0.054 mni− 1, 0.0024–0.0326 min− 1 under influence of applied voltage and sodium chloride, respectively. The maximum values of consumption energy were 0.93 and 0.55 Wh/mg using 0.1 g NaCl and 7 volt, respectively. Some chlorinated transformed products were selected and elucidated which were C13H18Cl2NO5, C11H10Cl3NO4 and C13H13Cl5NO5 using LC-TOF/MS.

This review summarizes the literature data reported from 2000 up to the present on the development of various electrochemical (voltammetric, amperometric, potentiometric and photoelectrochemical), optical (UV-Vis and IR) and luminescence (chemiluminescence and fluorescence) methods and the corresponding sensors for rifamycin antibiotics analysis. The discussion is focused mainly on the foremost compound of this class of macrocyclic drugs, namely rifampicin (RIF), which is a first-line antituberculosis agent derived from rifampicin SV (RSV). RIF and RSV also have excellent therapeutic action in the treatment of other bacterial infectious diseases. Due to the side-effects (e.g., prevalence of drug-resistant bacteria, hepatotoxicity) of long-term RIF intake, drug monitoring in patients is of real importance in establishing the optimum RIF dose, and therefore, reliable, rapid and simple methods of analysis are required. Based on the studies published on this topic in the last two decades, the sensing principles, some examples of sensors preparation procedures, as well as the performance characteristics (linear range, limits of detection and quantification) of analytical methods for RIF determination, are compared and correlated, critically emphasizing their benefits and limitations. Examples of spectrometric and electrochemical investigations of RIF interaction with biologically important molecules are also presented.
