Summary: In this study, APEI beads were quaternized to enhance the sorption of Cr(VI), with optimal pH of 2 for both sorption and reduction. The reduction-assisted sorption mechanism boosts the global removal of chromate, while the sorbent's stability for Cr(VI) removal was confirmed through three successive sorption and desorption cycles. The interactions between the sorbent and Cr(VI) were further elucidated using Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS).

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
