“…These electrodes are highly compact because a single SPCE contains three electrode parts representing a three-electrode system. SPCEs have been reported to exhibit good selectivity and sensitivity as sensors for dopamine, ascorbic acid, and paracetamol [16]- [19].…”

In this study, we investigated the effect of modified material on screen-printed carbon electrode (SPCE) for detection of oxalic acid. The SPCE was modified with (1) carbon conductive ink and (2) combination of carbon conductive ink and nickel nanoparticles (Ni-NPs). Modification process of (1) was conducted using drop-cast method by adding a mix of carbon conductive ink and nickel nanoparticles (1:1) on the surface of SPCE. Modified SPCE was then dried and stored in desiccator. Performance test of SPCE with and without modification was carried out using cyclic voltammetry (CV) method. The CV scan was done at the range of-0.5 to 1.5 V with scan rate of 100 mV/s in 20 mM oxalic acid solution. The result showed that carbon conductive ink and nickel nanoparticles mix (1:1) modified SPCE could be used to detect oxalic acid on potential 1.2 V.

In this study, iron doped ZnO nanomaterial was synthesized by co-precipitation method and its surface properties were studied using Fourier transform infrared (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and UV-Vis spectroscopy. The characterization results con rmed that the synthesized Fe-ZnO nanoparticle exhibits good crystalline nature possessing wurtzite hexagonal phase and good optical properties. The synthesized Fe-ZnO nanomaterial modi ed glassy carbon electrode (Fe-ZnO/GCE) was used for the electrochemical determination of endrin pesticide in fruit juice samples. Compared to the bare glassy carbon electrode, the modi ed electrode, Fe-ZnO/GCE, showed remarkable electrocatalytic properties and an enhanced sensitivity for the determination of target analyte. It also exhibited a good linear response to endrin in the concentration ranging from 0.1 to 70 µM. The limit of detection (LOD) and limit of quanti cation (LOQ) of the method were 0.019 µM and 0.065 µM, respectively. Moreover, Fe-ZnO/GCE was selective for endrin analysis. It has also showed long-term stability, good repeatability and within-lab reproducibility. The practical utility of Fe-ZnO/GCE was applied for the determination of endrin in mango and orange juice samples. The relative recoveries of the real samples were ranged from 91.4-106.5%. The developed method could be used as good candidate for monitoring of endrin pesticides in food samples and other similar matrixes.
