| Outline of Final Research Achievements |
Washing remediation with chelators has been a widely evaluated option to treat contaminated soils containing As, Pb, Cd etc. We developed a rapid and high efficient remediation method for soil washing using biodegradable chelating agents. The washing system consists of new techniques based on fine-bubbling, mechanochemical reaction and biodegradable surfactant. We also establish a new technique for speciation analysis of metal-chelator complexes in aqueous matrices, and show the degradation behavior of biodegradable chemicals in the environment.

| Academic Significance and Societal Importance of the Research Achievements |
自然由来汚染土壌の浄化において技術革新が望まれる課題は、土地開発の現場で発生する莫大な汚染土壌を貯留することなく低コストで処理可能な迅速かつ高効率な環境技術の開発である。本研究では、環境技術を「使える」から「広げる」ことに目標を定め、キレート洗浄の迅速化・高効率化を達成した。本法は、現行の土壌洗浄システムに組み込むことが可能であり、汚染土壌やその他の廃棄物に対して連続洗浄法への発展が期待できる。
