Abstract
The study of the occurrence of humic substances present in natural waters and their physico-chemical properties, in particular their complexing behaviour, constitutes the main objectives of this research programme. In the first part, the report presents the description of the selected aquifer (representative of a granitic geological formation: Fanay-Augeres), the method for the collection and concentration of the humic substances (a sorption technique) and their characterization by different physico-chemical techniques (elementary and mineral composition, spectroscopic properties, size, proton capacity, datation). The results show that Fanay-Augeres humic substances (considered as site-specific humic substances) represent 41% of the total organic carbon (TOC) present in the aquifer (2ppm) and have properties similar to other aquatic humic substances. The second part describes the study of the interactions occurring between these humic substances and trivalent cations (Eu and Am). Two different analytical methods have been developed to perform these investigations: spectrophotometry and size-exclusion chromatography. Interaction constants and complexing capacities have been determined and compared with literature data. Fanay-Augeres humic substances present complexing for trivalent actinides which agrees with published data. Further developments needed in complexation studies are described. 10 figs.; 15 tabs.; 39 refs.
