One-step fabrication of chitosan-Fe(OH) beads for efficient adsorption of anionic dyes.

In this study, we reported the one-step synthesis of chitosan-Fe(OH) beads without the use of acid solvent, which could be used as effective adsorbents for anionic dyes removal. The preparation process was easy and green. The as-prepared beads were characterized for structural and morphological analysis in detail using several techniques, such as Scanning Electron Microscope, Fourier Transform Infrared Spectroscopy, X-Ray Diffraction, X-ray photoelectron spectroscopy and Thermogravimetric analysis.
