Adsorption of Indium(III) Ions from an Acidic Solution by Using UiO-66

Considering environmental friendliness and economic factors, the separation extraction of indium under acidic conditions are great significance. In this research, metal-organic frameworks (MOFs) UiO-66 were successfully prepared used for adsorption indium. The properties structurally characterized using powder X-ray diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), Brunauer-Emmett-Teller surface area analyzer (BET), thermogravimetric analysers (TGA) Scanning Electron Microscope (SEM). results show that can resist acid keep its structure unchanged, even at a strong acidity pH 1. performance to (III) was also evaluated. process ions by Langmuir isotherm, with maximum capacity 11.75 mg·g−1 being recorded. kinetics experiment preferably fits second-order kinetic model. A possible mechanism In(III) explored through photoelectron spectroscopy (XPS) Fourier transform infrared analysis(FT-IR). It concluded C=O free –COOH involved in cation exchange. This study indicates, first time, be applied as an acid-resistant adsorbent recover (III).
