![]() ![]() ![]() The filters were able to maintain their structural integrity and filtration performance even after multiple cycles of use and regeneration. ![]() In addition to their potential for removal of contaminants from water, the filters also exhibit excellent mechanical properties with a Young’s modulus value off about 1200 MPa, demonstrating their potential for use in practical water treatment applications. The obtained 3D printed and functionalized and (aka filters exhibit high efficiency in removing heavy metal ions from mine effluent and methylene blue from contaminated water, as demonstrated through batch adsorption experiments. Stable deposition of SU-101 distributed homogenously over the filter surface was achieved and confirmed by FT-IR, XPS and SEM measurements. The two tested anchoring methods were hydrolysis via either concentrated hydrochloric acid treatment or via a photooxidation reaction using UV – ozone treatment. This work summarizes a scalable and sustainable method of anchoring a green metal-organic framework (MOF) SU-101 onto the surface of 3D printed, biobased matrices built of polylactic acid (PLA) – based composites reinforced with TEMPO − oxidized cellulose nanofibers (TCNF). Multifunctional, biobased materials processed by the means of additive manufacturing technology can be highly applicable within the water treatment industry. ![]()
