Boosted Cr(VI) sorption coupled reduction from aqueous solution using quaternized algal/alginate@PEI beads

Yue Zhang et al.

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).

Transformation details of poly(acrylonitrile) to poly(amidoxime) during the amidoximation process

Dadong Shao et al.

Summary: The amidoximation process is crucial for optimizing the physicochemical properties and adsorption capabilities of PAO-based materials. Increased temperature, time, and NH2OH concentration lead to higher extent of amidoximation reaction, but excessively high temperature and long time can degrade PAO's surface properties and decrease its adsorption capability. The optimal condition for the highest U(vi) adsorption capability was found to be 3 h, 60 degrees C, and 50 g L-1 NH2OH.
