“…Yin, Chen, and Chen (2019) constructed a quenched electrochemiluminescence (ECL) sensor by shaping ZnO and g‐C 3 N 4 composites on GCE for fipronil analysis. The ZnO@g‐C 3 N 4 composites had strong ECL signal which was remarkably decreased with the presence of fipronil because of its quenching effects on ECL emission.…”

This paper reviews studies published in 2019, in the area of analytical techniques for determination of pesticides and herbicides. It should be noted that some of the reports summarized in this review are not directly related to but could potentially be used for water environment studies. Based on different methods, the literatures are organized into six sections, namely extraction methods, electrochemical techniques, spectrophotometric techniques, chemiluminescence and fluorescence methods, chromatographic and mass spectrometric techniques, and biochemical assays.

“…Modified working electrode carbon-nanotube (MWCNT)-glassy carbon electrodes (GCEs) (Montes et al, 2016), Graphite-polyurethane (GPU) composite electrode (Okumura et al, 2016), and ZnO@g-C3N4 modified glassy carbon electrode (Yin et al, 2019), and FeO.TiO2-CPE (Nurdin et al, 2019a) have been reported to be able to detect fipronil compounds in different samples. Although the modification of the electrode shows high sensitivity with a low detection limit, electrode modification is still an interesting study in the past year.…”

The new composite material Al(III)-TiO2 has been synthesized and applied as a modifier of graphene paste electrode for the determination of fipronil pesticide by cyclic voltammetry. The methods were to synthesis of Aluminum-Titanium dioxide (AT), preparation of graphene paste electrode with mass varied Al(III)-TiO2 (GAT) (0.05 g, 0.1 g, 0.2 g), and fipronil electroanalytic respons. Addition of Al(III)-TiO2 to the graphene paste electrode shows redox properties which are well characterized by a fast electron transfer process. Based on the results of measurements in a solution containing fipronil, it is known that fipronil is oxidized at a potential value of 0.26 V. Furthermore, the fipronil oxidation process on the GAT surface is influenced by diffusion control, this is powered by R2 value 0.91 when plotted between peak oxidation currents (Ipa) vs. root scan rate. Other results show that measurement linearity is in the range 0.01 to 0.09 µg/L with a limit of detection (LOD) value of 0.0164 μg/L. Moreover, GAT shows good stability in the determination of fipronil with% RSD equal to 5%.

“…In recent years, electrochemiluminescence (ECL) as a newly developed analytical method has obtained considerable attention from researchers because of its simple equipment, easy operation, fast response, and high sensitivity, 9,10 whose applied light is produced by the substance at excited state returning to the ground state. 11 Among the ECL systems, the luminescence system based Ru(bpy) 3 2+ has been mostly applied in various elds for its high luminescence efficiency, good solubility, high chemical stability, and regenerability.…”
