Fabrication of ZIF-8 based on lignin with high yield for dye removal from water
Abstract The hybrid nanocomposites ZIFL composed of Zn-based MOFs (ZIF-8) and lignin were successfully synthesized via a simple one-step method at room temperature. The yield of the hybrid nanocomposites ZIF@L were up to 52% and the synthesis time was greatly shortened. Characterization using FT-IR, XRD, SEM and $ N_{2} $-sorption analysis indicated that ZIF@L composites exhibited rhombic dodecahedral structure such as the parent ZIF-8 synthesized in the absence of lignin and the incorporation of lignin did not destroy the framework integrity of ZIF-8. The ZIF@L composites were used to remove methyl violet (MV). The ZIF@L nanocomposites had a remarkable improvement in adsorption capacity of MV compared with the parent ZIF-8. The modified Langmuir model fitted better the equilibrium data of MV adsorption on the ZIF@L-4 composite and the maximum adsorption capacity of MV is 1001.2 mg $ g^{−1} $. The pseudo-second-order model could describe well the kinetics process of MV dye onto the prepared adsorbents..
