Abstract

Abstract

Ultrasound-assisted wet impregnation method was used to prepare the Fe₂O₃/γ-Al₂O₃ sorbent. The effects of the precursor solution content, carrier size, adsorption temperature and atmosphere on the arsenic capture efficiency in a fixed-bed reactor were investigated. The results show that the precursor solution concentration and the size of carrier can affect the arsenic adsorption efficiency. The increasing of adsorption temperature enhances the chemical adsorption ability. However, the efficiency will be decreased if the temperature is over 600 ℃. The addition of SO₂ in the atmosphere will enhance the arsenic adsorption ability of Fe₂O₃/γ-Al₂O₃. The influence of NO on the capture efficiency is not significant during this study.
