In this study, an electrochemical sensor based on AB nanoparticles was developed for sensitive detection of ISO, and the excellent performance and stability of the sensor were demonstrated.
The unreasonable use of isoproturon (ISO) had caused severe damage to human health and the ecological environment. Herein, an ultrasound-assisted strategy was proposed to construct a novel electrochemical sensor based on acetylene black (AB) nanoparticles for the sensitive determination of ISO. The morphological characterization of AB was investigated by scanning electron microscope (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). AB with pearl-chain-like carbon network exhibited outstanding electrical conductivity and prominent dispersion ability, which could significantly improve the electrochemical detection performance of ISO. The linear range of detecting ISO was 0.5-20 ??M with the detection limit of 0.096 ??M at the fabricated AB/GCE sensor. Moreover, the fabricated sensor demonstrated good stability, repeatability, and selectivity. The AB/GCE sensor presented acceptable recoveries of 98.21%-102.70% in measuring ISO in tomato and water samples. This work lays an essential foundation for using AB nanoparticles to develop high-performance ISO sensor.
