“…Though highly sensitive and allowing multi drugs analysis, these conventional analytical techniques are routinely used to quantify DCF residues in surface and ground waters, but are time-consuming, expensive, require a lot of expertise to be operated and are not easy to be deployed in the field.

Diclofenac (DCL) is a nonsteroidal anti-inflammatory commonly prescribed to treat inflammatory joint diseases and mild to moderate pain. DCL residues have often been detected in freshwater environments and it belongs to the list of emerging pollutants (EPs) because of the risk it presents for health and environment. Many studies have described the potential effects of DCL on organisms when exposed to environmental levels ranging from a few ng L À 1 to tens of μg L À 1 in surface water. Until now, its detection essentially depends on conventional techniques, such HPLC and GC/MS. Although these analytic techniques are very robust, they are expensive, require experts, and are not portable. Electrochemical sensors are an attractive alternative. They provide many benefits over thermal, optical, and piezoelectric detection including ease of use, rapidity, costeffectiveness, high sensitivity and selectivity, ease of miniaturization and robustness. The aim of this review is to report electrochemical methods used for the detection of DCL and to describe strategies for improving performances of each sensors.

Sodium diclofenac (DCF) presence reported in water use cycle at various concentrations including trace levels necessitates continuous development of advanced analytical method for its determination. In this work, ease electrochemical methods for DCF determination based on voltammetric and amperometric techniques were proposed using a simple combination of graphene with multi-walled carbon nanotubes as paste electrode. Integration of the graphene with multi-walled carbon nanotubes enlarged the electroactive surface area of the electrode and implicitly enhanced the electrochemical response for DCF determination. On the basis of the sorption autocatalytic effect manifested at low concentration of DCF, we found that the preconcentration step applied prior to differential-pulsed voltammetry (DPV) and multiple-pulsed amperometry (MPA) allowed for the enhancement of the electroanalytical performance of the DCF electrochemical detections, which were validated by testing in tap water. The lowest limit of detection (LOD) of 1.40 ng·L−1 was found using preconcentration prior to DPV under optimized operating conditions, which is better than that reached by other carbon-based electrodes reported in the literature.

Cefpirome, which is a fourth-generation cephalosporin, was analyzed for the first time at a glassy carbon electrode using differential pulse voltammetry in this novel method. Different experimental conditions were optimized, such as pH and electrolyte type, to achieve a high peak current. Under the optimum conditions, the oxidation of cefpirome exhibited diffusioncontrolled process depending on pH. Cefpirome was electrochemically determined at the linear range between 2-200 µM, and the detection limit was found as 0.167 µM in pH 4.7 acetate buffer solution. Analysis results showed that the proposed electrochemical method could be used for the determination of cefpirome in human urine samples. A linear relationship has been obtained in the concentration range of 2-10 µM. At the same time, the detection limit was found as 0.101 µM for cefpirome in human urine. Moreover, to check the selectivity of the proposed method, the effect of some interference species, including ascorbic acid, uric acid, dopamine, glucose, Na + , K + , Ca +2 , NO 3 -, have also been investigated. As a result, a simple, sensitive, reproducible, no time-consuming, and more environmentally friendly method was developed when compared to the literature studies.
