模拟酸雨淋溶下海泡石复合材料对污染土壤镉释放的影响
|
摘要
为了探究改性海泡石材料对土壤中重金属的钝化效果,采用土柱模拟酸雨淋溶方法研究了天然海泡石(SEP)、二乙基二硫代氨基甲酸钠改性海泡石(SEP-DDTC)、3-巯丙基三乙氧基硅烷改性海泡石(SEP-MPTES)对污染土壤中Cd的淋溶效应。结果表明:p H=4. 0的酸雨淋溶后土壤p H值上升了0. 80～0. 99个单位,淋出液的p H值也明显上升。SEP和SEP-MPTES处理Cd的累积淋溶量分别增加66. 45%和11. 49%,SEP-DDTC处理显著减少45. 98%。SEP-DDTC和SEP-MPTES处理酸雨淋溶后3层土壤有效态Cd含量均低于对照,SEP-DDTC处理比SEP-MPTES处理平均低0. 054 mg·kg-1,表明SEP-DDTC是一种潜在的土壤重金属Cd修复材料。
In order to investigate the immobilization efficiency of heavy metals in soil by functionalized sepiolite materials,the leaching effect of different materials,sepiolite( SEP),sepiolite-diethyldithiocarbamate( SEP-DDTC),sepiolite-3-mercaptopropyltriethoxysilane( SEP-MPTES) on soil polluted by Cd were measured by soil column simulated acid rain leaching. The results show that the p H values of soil increased by 0. 80 ～ 0. 99 after the leaching of simulated acid rain with p H 4. 0,and the p H values of leaching also increased obviously. When the acid rain p H value was 4. 0,compared with the CK treatment,the SEP treatment and SEP-MPTES treatment had significant increases in accumulation leaching amount of Cd by 66. 45% and 11. 49%,respectively. However,the SEP-DDTC treatment had a significant decrease in accumulation leaching amount of Cd by 45. 98%. Compared with three layers of soil available cadmium content after simulated acid rain,SEP-DDTC treatment and SEP-MPTES treatment were lower than CK,SEP-DDTC treatment was 0. 054 mg·kg-1 lower than SEP-MPTES treatment in average. It indicates that SEP-DDTC is a potential material for soil heavy metal Cd remediation.
