“…By comparing the performance characteristics of the Clay−CPE with other electrodes (Table ), it is clear that our modified electrode is far better regarding the ibuprofen determination with precision. The limit of detection and sensitivity are comparable to those of others electrodes . The reproducibility of clay‐CPE was also investigated in 1.0 × 10 −5 mol L −1 of ibuprofen and the relative standard deviation (RSD) was 2.31% for eight successive measurements.…”

“…Compared to previous reported results attained for the individual or the simultaneous determination of two of them using other electrodes (Table 4), e.g., multiwalled carbon nanotube modified basal plane pyrolytic graphite electrode by adsorptive stripping voltammetry [9], poly (4-vinylpyridine)/multiwalled carbon nanotubes modified glassy carbon electrode by DPV and CV [10], or carbon nanotube modified pyrolytic graphite electrode by CV or SWV [11] for the PA determination, the LODs obtained in this work are slightly higher. However, in comparison to other electrodes, such as carbon paste-multiwalled carbon nanotube composite electrode [17], poly(L-aspartic acid) modified glassy carbon electrode [18], or boron-doped diamond electrode [19] for IB determination by CV, DPV, SWV; gold nanoparticle-glassy carbon paste composite electrode [21], anthraquinone modified carbon paste electrode [22], or most of the electrodes considered in the review for CF determination by SWV, DPV, or stripping voltammetry [23]; nanogold modified indium tin oxide electrode [12], Nafion/TiO 2 –graphene modified glassy carbon electrode [13], C 60 -modified glassy carbon electrode [14], carbon ionic liquid electrode [15], or chitosan modified carbon paste electrode [16] for PA determination by CV, DPV, and SWV; HKUST-1 metal-organic framework-carbon nanofiber composite electrode for IB and diclofenac determination by CV [24]; boron-doped diamond electrode for the concurrent determination of PA and IB [25] or PA and CF [26] by DPV; and glassy carbon electrode for PA and phenobarbital determination by stripping voltammetry [27], the LODs achieved for the simultaneous determination of PA, IB, and CF by DPV using a SPCNFE are similar or even significantly better depending on the electrode considered. Moreover, it is worth noting that most of the sensors used for the determination of such analytes involved modifications of different complexity, whereas the proposed SPCNFE can be used, as it is commercially purchased without any previous modification or treatment, which greatly decreases the time dedicated to the electrode preparation, and with the additional advantages of screen-printed electrodes such as the low cost, disposable character, and the easy attachment to portable instrumentation facilitating the in-situ analysis.…”

“…Several papers devoted to the voltammetric individual determination of PA [9,10,11,12,13,14,15,16], IB [17,18,19,20], or CF [21,22,23], or at most the simultaneous determination of two of them [24,25,26,27] were reported in the literature. From these publications, it is worth noting that the determination is mostly carried out in pharmaceutical products or in the case of CF in beverages [23], whereas the voltammetric determination of such analytes in environmental samples has been barely investigated.…”

“…However, most of these techniques are expensive, require skilled personnel and involve tedious and time‐consuming sample preparation procedures. In consequence, electrochemical alternative techniques for ibuprofen determination were developed, which are as sensitive as the chromatographic, but simpler, faster, and cost‐effective [17–25] . The potential of the electrochemical methods in drug analysis is widely discussed in the literature, [26–38] along with the recent advances in ibuprofen electrochemical quantification [39–41] …”
