摘要：
In this study, hydrochar was synthesized using bocaiuva fruit peel for application in diuron removal from contaminated water through adsorption. The influence of the initial pH of the solution, hydrochar concentration, contact time, and temperature on the adsorption process were evaluated. The pseudo-second order kinetic model and the Langmuir isotherm model provided the best fits to the adsorption data. The maximum adsorption capacity was estimated at 10.06 mg g-1, at pH 4.0 and 30 degrees C. The activation energy calculated by the Dubinin-Radushkevich isotherm model was 7.805 kJ mol-1, indicating that a physical process is responsible for the adsorption of diuron on hydrochar. The thermodynamic parameters (AH < 0 and AG > 0) suggested that the adsorption process is exothermic and not spontaneous. The results indicated that hydrochar could be an alternative adsorbent for removing diuron from water.
