Abstract
Dialysate regeneration via uremic toxin removal remains to be studied. In this study, the removal of creatinine, one of the most water-soluble uremic toxins, using ZSM-5 zeolite as an adsorbent was investigated. The zeolite ZSM-5 was successfully synthesized (57 %) with a mole ratio of 0.1 Na2O:1 SiO:0.0125 Al2O3:20 H2O. Modification was performed using an imprinting technique with creatinine as the template to produce creatinine-imprinted ZSM-5 (IZ). Based on X-ray diffraction (XRD) characterization, the crystallinity of IZ was 67 %. The successful imprinting of creatinine onto ZSM-5 was confirmed by comparing the FT-IR and surface area analysis characterization results with those of the synthesized ZSM-5. The FT-IR spectra of IZ and synthesized ZSM-5 exhibited similar patterns, indicating that the zeolite framework was preserved during the imprinting process. IZ exhibited shorter contact time and higher adsorption capacity than synthetic ZSM-5.

Description of the data and file structure
The experimental work focused on the synthesis, modification, characterization, and application of ZSM-5 zeolite for selective creatinine removal from dialysate. ZSM-5 was synthesized via a hydrothermal method and subsequently modified using a molecular imprinting technique with creatinine as the template to produce imprinted zeolite (IZ). The materials were characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), surface area analysis, and SEM-EDX to confirm structural and physicochemical properties. Adsorption experiments were conducted to evaluate creatinine removal performance by optimizing parameters such as contact time, adsorbent dosage, and initial concentration. Additionally, the synthesized IZ was incorporated into a cellulose acetate-based mixed matrix membrane (MMM/IZ), and its performance was compared with powdered IZ for dialysate purification applications.
