Migration Behavior of Humic Acids in Compacted Clay and its Influence on the Uranium Transport

摘要

Clay minerals and organic substances are common components of many soils, sediments, and rocks. However, little is known on the migration behavior of humic substances in clay formations which is supposed to be governed by diffusion processes. Since humic acids (HA) show a strong ability for complex formation, they can influence the migration of radioactive and non-radioactive toxic metal ions in clayey environments.
