摘要：
The main valence states and existing forms of Tl in wastewater were analyzed by Factsage 8.0. MnO2 and Fe3O4@PB adsorbents were prepared and the effects of pH, initial concentration, adsorption time, adsorbent quality and coexisting ions on thallium adsorption in simulated water were investigated. The expanding experiments on the treatment of industrial thallium wastewater with adsorbents were carried out. The results show that Tl is mainly present in the wastewater as Tl+, and there is a small amount of [TlCl-4] in the homogenizing pool water. The thallium contents of the simulated water are reduced from 100 μg/L to 3.09 μg/L and to 2.97 μg/L using the Fe3O4@PB and MnO2 of 0.8 g/L, respectively, at the optimal pH after 10 min. The effect of coexistence ions Na+ and Cl− is negligible on the removal of thallium. The effluent concentration of thallium in homogenized pool water is less than 2 μg/L after 30 min at the optimal pH=5 using Fe3O4@PB as adsorbent. The effluent concentrations of thallium in recycle water No.1 and No.2 are both less than 2 μg/L after 30 min at the optimal pH using the Fe3O4@PB and MnO2 as adsorbent. © 2023 Central South University of Technology.
