| 中文摘要 | Immobilization of soil contaminated with arsenic is a remediation practice that does not reduce the total content of contaminants, but reduces the mobile and bio-available fractions in soil. This study investigated the effectiveness of red mud and modified red mud amendments for reducing the mobility of arsenic in contaminated soil. Red mud and modified red mud were mixed thoroughly with the contaminated soil at various dosages. The effectiveness of immobilization was mainly evaluated by the China Solid Waste-Extraction procedure for leaching toxicity-Horizontal vibration method (GB5086.2-1997) and US EPA Method 1311 TCLP test. The sequential extraction procedure experiment is discussed in order to investigate the mechanisms of arsenic immobilization by different soil amendments. The leaching experiment showed that the arsenic extracted by water was reduced by 64.1% in the soil sample treated with 10% FeCl(2) modified red mud compared with the untreated control. Sequential chemical extraction experiment have shown that after soil was treated with red mud and modified red mud, the exchangeable arsenic fraction was strongly reduced and converted into more stable forms. |
