摘　　要：评述了近年来与高放废物深部地质处置有关的地质环境中Am化学的研究进展,讨论了Am在地下水中的存在价态、溶解度、配合反应(包括水解反应)、胶体的形成等对迁移的影响。提出了近期和长期应开展的若干研究课题。This paper presents characteristics and disposal technique of high level radioactive wastes （HLW）, and reviews a progress in the study on the chemical behavior of Am, a transuranie element possing long-term potential risk to the environment, under the geological repository. The effect of the basic chemical reactions of Am possibly happening in groundwater, including solubility, complexation, and colloidal generation, on the migration are discussed. Some proposals for further work in China are also suggested.
