Adsorption Removal of Imidacloprid Insecticide in Agriculture Industry Using MoO3 Nanorod

Insecticides are chemicals used to control insects by killing them or preventing them from engaging in undesirable or destructive behaviors. Imidacloprid is an insecticide made to mimic nicotine. Nicotine is naturally found in many plants, including tobacco, and is toxic to insects. Imidacloprid is used to control sucking insects, termites, some soil insects, and fleas on pets. In this study, imidacloprid removal was investigated by synthesized MoO3 from an aqueous solution. For this purpose, FT-IR, XRD, UV–Vis, SEM, and EDS were used to characterize the synthesized nano adsorbents and to determine the removal process. Batch adsorption studies were conducted to investigate the effect of temperature, initial Imidacloprid concentration, and adsorbent count and contact time as important adsorption parameters. The maximum equilibrium time was 25 min with 5 mg adsorbent at 45ºC and pH=7 for MoO3. All the adsorption equilibrium data were well fitted to the Freundlich and Langmuir isotherm model with heterogeneous, multilayer, temperature-dependent, irreversible, and nonspontaneous behavior. The ∆H is 0.2 J, and the ∆S is 2.3 J mol-1K-1.
