Abstract

Abstract

The chemical forms of arsenic (As) in soil environment were sophisticated, and there was a defect in the treatment of different forms of As with conventional solidification and stabilization materials. We integrated the surface adsorption of biochar (BC), pore filling, electrostatic attraction, complexation and co-precipitation oxidation-reduction of ferric manganese binary oxides (FMBO), then a new functional material BC_FM was prepared and stabilized with Portland cement. The effect of key parameters on treatment effect was discussed by response surface method. The results showed that when the ratio of BC_FM to Portland cement was 9.88% and 8.80%, and the curing time was 20.53 days, the minimum leaching concentration of As was 0.055 mg/L, the exchangeable state proportion was reduced from 4% to 0.5%, the residual state proportion was increased from 77% to 87%, and the unconfined compressive strength exceeded 50 kPa. It was speculated that the curing and stabilization mechanism of BC_FM was the combination of Fe-O(H)-As coprecipitation, Mn-O(H)-As oxidation and BC function. The results of this study provide a new technical scheme for long-term curing and stabilization of As.
