  • 摘要: 本研究利用二氧化锰改性的蛭石-蒙脱土（VER-Mt）为钝化剂，在室内盆栽试验的条件下进行煤矸石充填区镉污染土壤的钝化修复研究，分析了VER-Mt的添加对土壤pH值、土壤镉各形态分布、青菜生长状况及青菜各部位镉含量的影响.结果显示，VER-Mt的添加能够提高土壤pH值；当VER-Mt添加量为35 g·kg-1时，土壤可交换态及碳酸盐结合态镉含量分别降低46.06%和30.80%，而残渣态镉含量则增加了65.40%；VER-Mt对青菜具有增产增收的效果，其株高、茎叶鲜重、根系鲜重最多增加了73.24%、83.93%、78.07%；VER-Mt能够有效降低青菜不同部位镉含量，其中茎叶部分镉含量可从0.053 mg·kg-1降低至0.029 mg·kg-1，根系部分镉含量可从0.133 mg·kg-1降低至0.079 mg·kg-1.研究结果表明，VER-Mt作为新型钝化剂能够达到修复煤矸石充填区镉污染土壤、提升农产品质量安全的目的.
    Abstract: In this study, indoor pot incubation experiments were conducted to study the inhibition ability of passivating agent manganese dioxide-modified vermiculite-montmorillonite (VER-Mt) on cadmium (Cd) in contaminated soils from coal gangue filling and reclamation areas. The effects of VER-Mt addition on pH values and Cd distribution of soil, growth of green vegetables as well as Cd contents in different parts of green vegetables were investigated. The results were summarized as follows. the addition of VER-Mt could effectively increase the soil pH values. When the addition amount of VER-Mt was set as 35 g·kg-1, the soil exchangeable and carbonate-bound Cd decreased by 46.06% and 30.80%, respectively. Meanwhile, the soil residual Cd increased by 65.40%. The addition of VER-Mt could increase the yields of green vegetables: the plant height, stem and leaf fresh weight, and root fresh weight increased by 73.24%, 83.93%, 78.07%, respectively. The addition of VER-Mt could effectively reduce Cd concentrations in different parts of green vegetables: the Cd concentrations in stems and leaves were reduced from 0.053 mg·kg-1 to 0.029 mg·kg-1, and from 0.133 mg·kg-1 to 0.079 mg·kg-1, respectively. Therefore, VER-Mt, as a new type of passivation agent, could remediate the Cd-contaminated soils from coal gangue filling and reclamation areas and improved the quality and safety of agricultural products.
