Abstract

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.

Methods

Three different loading of Imazethapyr have been incorporated in chitosan bentonite clay composites, ratios starting from 3.14:1, 1.26:1, and 1:1 of Chitosan clay and Imazethapyr were prepared and confirmed the formation of nanocomposites. An acidic medium has been identified for the preparation of chitosan clay nanocomposites.

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.
