Abstract

Abstract

In this study, the simplex-centroid design method (SCMD) was used to model and optimize the mixing ratio of FeSO₄·H₂O zero-valent iron (ZVI) and manganese dioxide (MnO₂) as the raw materials, and a new composite Fe-based stabilizer was designed and developed, and then applied to the stabilization of arsenic-containing residue. The results showed that the optimum combination for high As stabilization performance and low cost of stabilizer was the mixture of 65.05, 10.00 and 24.95 % FeSO₄·H₂O, ZVI and MnO₂. The leaching concentration of As decreased from 162 mg/L to 0.645 mg/L, lower than the limit value(1.2 mg/L) prescribed in China. The stability mechanism of As in ACR was studied by SEM-EDS, FTIR and XPS, while the available As was stabilized by adsorption, complexation and precipitation of Fe/Mn (hydride) oxide and Fe(Ⅲ), forming stable amorphous Fe/Mn-As. The composite Fe-based stabilizer combined with H₂SO₄ obtained excellent stability of As through a process of release-oxidation-stabilization. This study provides an sound theoretical basis for design of multi-component composite stabilizers and effective stabilization of arsenic-containing residue.
