Room temperature synthesis of biocompatible nano Zn-MOF for the rapid and selective adsorption of curcumin

Abstract

Nanoscale metal-organic frameworks (MOFs) have appeared as potential materials in biomedical and sensing applications. In this work, a nano Zn-BDC-NH2 encoded MOF was effectively synthesized using the co-surfactants strategy and characterized for the curcumin adsorption. The analysis of the synthesized MOF by using characterization techniques, including XRD, SEM, N2 isotherm sorption, TGA, and FT-IR revealed that the nanomaterial exhibited similar structure structural and other physical properties to the original framework, but its particle size was very small of about 50 nm. As a result of the curcumin (CUR) adsorption investigation, the nanomaterial showed a high adsorption capacity on Zn-BDC-NH2 up to 179.36 mg·g−1 and faster adsorption in comparison with reported adsorbents. The results suggest that the nano Zn-BDC-NH2 MOF can be considered as a promising material for bio-applications.
