Abstract :

Imidacloprid as an insecticide is one of these pesticides, which has high toxicity, relatively high solubility and long-term stability in water, and has created a significant environmental concern. In this research, the removal of imidacloprid pesticide was investigated by using MIL-100(Fe) adsorbent and UV-Vis device. The effects of different parameters such as time, pH, and adsorbent on the adsorption process were investigated. Optimization of effective parameters was shown that at pH=3, 60 minutes, and 5 mg adsorbent, 66% of the pollutants were removed from the aqueous solution. Also, the adsorption isotherms and kinetics of this pollutant were studied on the MIL-100 (Fe) adsorbent, which indicated that Langmuir adsorption isotherm model was more consistent with the Freundlich adsorption isotherm model, and the kinetics of this reaction follow the quadratic equation.
