Soybean residues were transformed through static pyrolysis carried out at temperatures between 250°C and 350°C. Through the analysis of the gaseous fraction, it was found that the gases emanated in the pyrolysis are mainly CO2 and CO. Furthermore, it was proved that this methodology constitutes a simple way to obtain useful carbons for the capture of pesticides present in an aqueous matrix. For example, the concentration of Chlorothalonil in a 7:3 water:acetonitrile solution decreases by 76-77% through adsorption on the carbons obtained.
