Abstract

In this study, adsorption behaviors and mechanism of Sb(III) ions onto Fe(III)-treated humus sludge adsorbent (FTHSA) from aqueous solutions was investigated using batch adsorption techniques, Fourier transform infrared (FT-IR) spectra and scanning electron microscopy coupled to an energy
dispersive spectrometer (EDS). FTHSA was prepared via immersing with 1 mol/L FeCl3. The effects of dosage, contact time, Sb(III) initial concentration and pH on the adsorption of Sb(III) onto FTHSA were investigated. Sb(III) adsorption was favored at pH with 2.0 and decreased dramatically with increasing pH. The description of equilibrium data of Sb(III) adsorption by Langmuir, Freundlich and
Dubbin-Radushkevich isotherm models showed that Langmuir model provided the best fit for Sb(III) adsorption with maximum adsorption amount of 9.433 mg/g. Pseudo-first-order, Pseudo-secondorder, Elovich and Intraparticle diffusion model were applied to describe the adsorption process of
Sb(III) ions onto FTHSA. The results showed that pseudo-second-order model described well for Sb(III) adsorption and chemical adsorption played a dominant role in the adsorption process. The FTIR spectra also indicated that the chemical interactions as ion exchange among the metal ions and NH, O-H, C=O, COO, C-O were mainly involved in the adsorption process. Therefore, FTHSA has a
suitable potential removal for Sb(III) ions in practical process.
