Preparation of Chitosan Clay Imazethapyr Nanocomposite and itsCharacterization

Background: Imazethapyr belong to Imidazolinone herbicides used as a selective, pre and post-emergent herbicide and widely used in the soybean crop, and considered one of the most leaching potential herbicides. Objective: In the process of making nano composites of chitosan bentonite clay, Imazethapyr has been developed in this research programme. The material used to make the nanocomposites of Imazethapyr was based on the exoskeleton of crustaceans such as shrimps, lobsters, and crabs, and organic clay like bentonite. Results: The formation of composites has been further confirmed by Fourier-Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), and Field Emission Scanning Electron Microscopy (FE-SEM). Differential Scanning Calorimetry (DSC) and Thermal Gravimetric Analysis (TGA) have been used to understand the thermal properties of chitosan bentonite clay Imazethapyr nanocomposites. Conclusion: Analytical data clearly revealed the formation of nanocomposites of chitosan bentonite Imazethapyr in the acidic media.
