Selective Laser Sintering of a Chitosan/MOF Composite: 3D-Printed Adsorbent for Arsenic.

ABSTRACT: Metal-organic framework/biopolymer composites have shown significant potential for removing pollutants such as arsenic from aquatic environments. However, due to the poor mechanical properties and challenges in incorporating these materials into existing water treatment systems, their use in real-world applications is limited. In this study, we developed mechanically strong porous filters for adsorbing arsenic (As-(III) and As-(V)) by utilizing the selective laser sintering (SLS) 3D printing technique. In the printed filter disks, polystyrene is used as the polymeric supporting matrix, and a bimetallic Mn-doped MIL-100-(Fe)-based MOF/chitosan composite CS-MIL-100-(Fe, Mn) (hereafter: CS/MOF) as the adsorptive filler, with 5, 10, and 15 wt % filler concentrations.
