- Title
Polymer Nanoparticles: Adsorption and Desorption of the Weedkiller Tebuthiuron Turned to Green Chemistry.

- Abstract
The herbicide Tebuthiuron is one of the main responsible for controlling and combating weeds in sugarcane plantations. Its degree of toxicity and its half-life are the main factors for the degradation of the environment. In order to reduce the amount of product used, an anchoring study of the herbicide in polymeric nanospheres was carried out to study the degree of controlled release, observing factors such as conductivity and pH variation. The results of conductimetric titrations and UV analysis in the visible region showed the efficiency of the chitosan nanospheres in the controlled release process of the herbicide, demonstrating that the best pH range for release is from 6.3 to 7.2. This study is a precursor of new activities that will guide further research to work on reducing the half-life of Tebuthiuron, reducing production costs and preserving the environment.
