摘要

A 3D-printed adsorbent is developed for dye adsorption. A composite of graphitic carbon nitride (g-C3N4) and cyclodextrin polymer (CDP), CDP-g-C3N4, was prepared through polymerization of cyclodextrin and epichlorohydrin in the presence of g-C3N4. The composite, 3D-CDP-g-C3N4, was transformed to a monolith via a DLP 3D-printer. The efficiency of 3D-CDP-g-C3N4 for Methylene Blue removal was examined and the effects of variables were investigated. The results underlined that in basic condition (pH = 10) at 80 °C dye removal reached to 91% in 90 min. The comparison of the dye adsorption of the adsorbent with CDP-free sample approved the role of CDP in adsorption, which originated from the formation of inclusion complex with dye. Furthermore, it was confirmed that 3D-printing had a dual role in adsorption and not only provided a monolithic form, but also improved adsorption through interactions with dye. 3D-CDP-g-C3N4 was utilized for adsorption of other non-steric cationic and anionic dyes. Kinetic study exhibited that the activation energy was 15.26 kJ mol− 1. Thermodynamic parameters, i.e. enthalpy and entropy were calculated as 11.59 kJ mol− 1, and 40.38 J mol− 1 respectively. This research presents a novel integration of bio-based functional materials and 3D printing technology, offering a versatile platform for wastewater treatment.
