摘要: The work is concerned with a bentonite hydrochar composite made from bentonite and cassava peel. Bentonite was obtained from a Ponorogo deposite, Indonesia, and cassava peel was agricultural waste. The preparation of the composite was carried out at 500° C under a flow of carbon dioxide. The sample was characterized by argon adsorption at 87 K, X-ray diffraction, scanning electron microscope, and Fourier transform infrared spectroscopy methods. The adsorption of ammonium from the solution was conducted in a batch condition …
