摘要：

The adsorption of aqueous monuron and metals by coffee waste as a low-cost material is reported using batch experiments. Coffee waste with minimal processing and coffee waste pyrolyzed at 500 degrees C were used for the adsorption of monuron. For metals, only the unpyrolyzed coffee waste was used. Monuron was determined by high-performance liquid chromatography with diode array detection, and metals were determined by inductively coupled plasma-mass spectrometry. The specific surface areas of the adsorbent materials were calculated using the Brunauer-Emmett-Teller equation. The removal rates of monuron and metals were determined quantitatively.
