Removal of arsenites onto akaganeite-type adsorbents
In this study, arsenites removal from aqueous solutions was investigated using synthetic prepared nanocrystalline akaganeite. The effects of various parameters, such as the solution pH, the ionic strength, the contact time of sorbent material with the treated solution, and the pollutant initial concentration have been investigated during this study. Typical adsorption isotherms were determined, which were found to sufficiently fit the typical Langmuir equation. The mechanism of sorption was examined by Fourier transmission infrared and X-ray photoelectron spectroscopy measurements.
