Synthesis of novel ZnAl2O4/Al2O3 nanocomposite by sol–gel method and its application as adsorbent
In this research, ZnAl 2 O 4 /Al 2 O 3 nanocomposites with different ZnAl 2 O 4 (30, 50, and 70 wt.%) were successfully prepared in one step by sol–gel method and utilized for the removal of methylene blue (MB). The structural properties of nanocomposites were investigated by X-ray diffraction (XRD)...

(30, 50, and 70 wt.%) were successfully prepared in one step by sol–gel method and utilized for the removal of methylene blue (MB). The structural properties of nanocomposites were investigated by X-ray diffraction (XRD), differential thermal analysis (DTA), FTIR analysis, Zeta potential, and BET. The obtained results showed the synthesized nanocomposites by sol–gel method were amorphous and heat treatment at 700 °C led to the crystallization of zinc aluminate spinel. The maximum MB removal (70%) was obtained under o9 ptimal conditions such as initial concentration of MB (10 mg/L), pH of solution (8.5), the amount of adsorbent (0.05 g), type of adsorbent (70 wt.% ZnAl
