GOALI: Engineered Sequestration and Bioavailability Reduction of Metals in Soils by Addition of Iron Oxides Recovered from Coal Mine Drainage Sites

0402966 Dzombak拟议的工作将评估一种潜在的重金属污染土壤修复技术的效力和经济可行性。这项技术使用了从废弃的煤矿场地中回收的氧化铁。这项工作将与两个工业合作伙伴合作进行，每个合作伙伴都拥有氧化铁回收和现场补救方面的专业知识。拟议的补救战略是创新的，特别吸引人，因为它利用了在补救/复垦其他污染场地(即酸性矿山排水场地)时产生的一种物质。这项研究将解决与氧化铁纯度、金属固定化能力以及固定化金属可使用既定方法提取的程度有关的问题。工程应用问题也将在该项目的后期阶段进行探讨。

0402966 Dzombak The proposed work would evaluate the efficacy and economic viability of a potential remediation technology for soils contaminated with heavy metals. This technology employs iron oxides recovered from abandoned coal - mining sites. The work would be carried out collaboratively with two industrial partners, each having expertise in iron oxide recovery and site remediation. The proposed remediation strategy is innovative and particularly appealing because it makes use of a substance produced during remediation/reclamation of other polluted sites (ie acid mine drainage sites). The study will address issues relating to iron oxide purity, metal immobilization capacity, and the extent to which immobilized metals are extractable using established methods. Engineering application issues will also be explored in the later stages of the project.
