dc.description.abstract© 2022 Wiley-VCH GmbH.In this work, we have proposed an electrochemical sensor for the detection of pesticides by using a ceramic composite with a SiO2 surface modified with Sm2O3 nanoparticles and C-graphite (SSMG), obtained by the sol-gel process and immobilized by adsorption in Meldola Blue cationic dye (MB). The composite was called (SSMG/MB), which was characterized by spectroscopic, electrochemical techniques, Fourier-transform infrared spectroscopy, and Cyclic Voltammetry. The proposed sensor was applied for the glyphosate electrochemical detection, using Differential Pulse Voltammetry, and, under optimized parameters has presented the linear response for the pesticide in the concentration range from 0.99 to 7.94 (μmol L−1; R2=0.9963; n=8). The calculated values for the detection limit and the quantification limit were 0.15 and 0.49 μmol L−1, respectively. Therefore, the new electrochemical sensor based on SiO2, NPsSm2O3, C-graphite, and MB hybrid material was developed for the first time for glyphosate determination, which has demonstrated high potential for the development of new hybrid devices for environmental control.
