  • 摘要: 锰氧化物对砷的去除有着环境和地球化学现实意义，本文通过批实验和柱实验研究湖南桃江锰矿对溶液中As（Ⅴ/Ⅲ）的去除行为差异和迁移行为.Langmuir吸附等温线结果表明，锰矿对As（V）和As（Ⅲ）的理论最大吸附量分别为1.32 mg·g-1和0.30 mg·g-1.As（Ⅴ/Ⅲ）在锰矿表面的动力学符合拟二阶动力学模型，表明锰矿吸附As（Ⅴ/Ⅲ）均属于化学吸附，受化学反应速率控制；反应吸附速率常数K2[As（Ⅴ）]>K2[As（Ⅲ）]，表明锰矿对As（Ⅴ）的吸附速率更快.锰矿在氧化As（Ⅲ）时，溶液中As（Ⅲ）减少速率与溶液中Mn浓度变化非常一致，表明砷的氧化行为与锰矿相关.CDE和Thomas吸附模型拟合As（Ⅴ）和As（Ⅲ）的迁移行为表明，Mn2+、Al3+、PO43-和SiO32-均会降低锰矿的最大吸附量和滞留因子，其中Al3+对As（Ⅲ）的吸附具有较强的拮抗作用，最大吸附量下降至0.002 mg·g-1，对As（Ⅴ）的拮抗作用相对较弱，而PO43-和SiO32-对As（Ⅴ/Ⅲ）在柱实验中的拮抗作用相近.研究为就地处理湖南地表和地下水砷污染提供了新的处理矿物.
    Abstract: Removal of arsenic by manganese oxide has environmental and geochemical significance. In this study, batch and column experiments were carried out to compare and analyze the differences in the removal and migration behavior of As(Ⅴ) and As(Ⅲ) in Taojiang manganese mine, Hunan Province. The langmuir adsorption isotherm showed that the maximum adsorption capacity of manganese ore for As(Ⅴ) and As(Ⅲ) was 1.32 mg·g-1 and 0.30 mg·g-1 respectively. The kinetics of As(Ⅴ/Ⅲ) on the surface of manganese ore conformed to the pseudo-second-order reaction, which indicated that the adsorption of As(Ⅴ/Ⅲ) was chemical adsorption, and was controlled by chemical reaction rate. The adsorption reaction rate constant was K2[As(Ⅴ)]>K2[As(Ⅲ)], indicating that the adsorption rate of As(Ⅴ) was relatively faster than that of As(Ⅲ). The reduction rate of As(Ⅲ) in solution was highly consistent with the change of Mn concentration in solution, showing that the oxidation behavior of As(Ⅲ) was related to manganese ore. CDE and Thomas adsorption model showed that Mn2+, Al3+, PO43- and SiO32- was reduced the maximum adsorption capacity and retention factor of manganese ore. Among them, Al3+ showed strong inhibitory effect to the adsorption of As(Ⅲ), and the maximum adsorption amount dropped to 0.002 mg·g-1. The inhibitory effect to As(Ⅴ) was relatively weak, while PO43- and SiO32- had similar inhibition to As(Ⅴ/Ⅲ) in the column experiments. The study provided new minerals for the in-situ treatment of arsenic contamination of surface and groundwater in Hunan Province.
