Özet

In this study, Zr-based metal organic frameworks (UiO-66) and graphene nanoplatelets UiO-66 nanocomposites (GNP/UiO-66) were prepared using acid promoted method, and used for adsorption of two different polyphenols; oleuropein and hydroxytyrosol. Different characterization techniques used for exploring the morphological and structure properties of the UiO-66 and GNP/UiO-66 nano composites. The adsorption of oleuropein and hydroxytyrosol was studied by UiO-66 and different GNP/UiO-66 nanocomposites and results showed that most of the oleuropein and hydroxytyrosol were removed from the solution in 60 min and 180 min, respectively. The kinetic modelling of adsorption was studied. The adsorption isotherms were constructed at different pH values. (C) 2019 The Korean Society of Industrial and Engineering Chemistry.
