Popis: The widespread use of carbendazim insecticides has caused substantial concerns to human health due to their coexistence, high toxicity, and persistence. Therefore, it is crucial to develop a carbendazim detection more important for the protection of both humans and the environment safety. A graphitic carbon nitride/europium molybdate (g-C3N4/EuMoO4) composite was fabricated using a simple coprecipitation method and utilized for the selective detection of carbendazim. The glassy carbon electrode (GCE) was fabricated with g-C3N4/EuMoO4 composite electrode (GCE/g-C3N4/EuMoO4) was simple, affordable, and offers an excellent platform for the detection of carbendazim. The structure formation was validated by suitable microscopic and spectroscopic techniques. Under optimal conditions, the GCE/g-C3N4/EuMoO4 electrode showed excellent electrochemical properties for the detection of carbendazim with a low detection limit (0.04 μM) (S/N = 3), a large linear response range of 50–400 μM, and high sensitivity (1.41 μAμM−1cm−2). The findings demonstrated that the developed method can be used to analyze food samples. The g-C3N4/EuMoO4 demonstrates greater sensitivity toward the electrochemical detection of carbendazim compared with the previous sensors. The GCE/g-C3N4/EuMoO4 electrode was utilized to detect carbendazim in real samples, and the results were satisfactory. Furthermore, the GCE/g-C3N4/EuMoO4 modified electrode offers several interesting properties, stability, reproducibility, repeatability, low cost, and practical applications.
