文摘

In situ U speciation was performed by using multiple DGT devices. Analyses were performed in a U mining area in Brazil. Total, cationic and anionic species were sampled by using three different ligands. Comparison of in situ and in lab deployments indicates sample modifications. Accurate measurements of U speciation must be performed in situ.
