Modular Chitosan-Based Adsorbents for Tunable Uptake of Sulfate from Water.

ABSTRACT: The context of this study responds to the need for sorbent technology development to address the controlled removal of inorganic sulfate (SO42-) from saline water and the promising potential of chitosan as a carrier system for organosulfates in pharmaceutical and nutraceutical applications. This study aims to address the controlled removal of sulfate using chitosan as a sustainable biopolymer platform, where a modular synthetic approach was used for chitosan bead preparation that displays tunable sulfate uptake. The beads were prepared via phase-inversion synthesis, followed by cross-linking with glutaraldehyde, and impregnation of Ca2+ ions. The sulfate adsorption properties of the beads were studied at pH 5 and variable sulfate levels (50-1000 ppm), where beads with low cross-linking sho
