The present work brings a compilation of selected data on aspects involving the adsorption of glyphosate in aqueous medium by in different materials. According to the information reported, the pH of the medium plays a fundamental role in the formation of glyphosate anions, thus affecting its behavior in adsorption by different materials. It was found that the Langmuir and Freundlich isothermal models respond more satisfactorily to the glyphosate adsorption process as a function of the type of adsorbent, and that the adsorption mechanisms respond to a greater degree to a pseudo-second-order kinetic model . Finally, it was found that clays, hybrid materials containing clays and biochar, were the matrices with the best adsorptive potential for glyphosate.

This work describes a novel synthetic route for obtaining 2-amino-naphthoxazoles derived from β-lapachone, which consists of a condensation reaction between β-lapachone and thiourea in a basic medium. This synthetic approach can be seen as a potential route for obtaining 2-amino-oxazoles from quinones. The obtained amino-naphthoxazoles were characterized by spectroscopic techniques and the crystal structure of one of them was resolved by X-ray diffraction. The experimental results were compared to that obtained through density functional theory (DFT) calculations, revealing high correlation coefficients.
