Abstract

One of the various types of pollutants is toxins, which have caused serious damage to the environment and humans due to excessive use in farms. Among these toxins is abamectin, which is used as a miticide. In this study, needle-like molybdenum trioxide nanorods were synthesized using a hydrothermal method, and a molybdenum trioxide@graphene oxide nanocomposite was synthesized heterogeneously. The characterization of the synthesized nanoparticles was performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), and infrared spectroscopy (IR), with an average size of 110 nanometers for the molybdenum trioxide nanorods. The results of this study compared these two compounds for the adsorption of abamectin toxin. The findings showed that both adsorbents have high adsorption capacity, and the molybdenum trioxide and graphene oxide nanocomplex has a greater adsorption capacity. The variables of toxin concentration, adsorbent amount, contact time, and pH in the adsorption process were examined. The results indicated that the adsorption capacity of the molybdenum trioxide nanorods is 95%, and the capacity of the synthesized nanocomposite is 98%. During condition optimization, it was shown that an adsorbent amount of 3 mg, a toxin concentration of 5 ppm, and a contact time of 15 minutes at acidic pH achieved the highest adsorption.
