5. Future Work FY01
In FY01 we will continue to:
" conduct desorption experiments of Pu(IV) on clinoptiolite to determine if sorption
onto colloids is an irreversible process. This is important in our understanding of the
long term behavior of Pu in groundwater.
" our experimental program using Pu(V). Pu(V) is the predominant form of plutonium
in the natural environment, so we will study its sorption and desorption onto the
clinoptilolite zeolite colloids following the same method as Pu(IV).
" use XAFS to determine the oxidation state of the Pu(V) after the experiment. These
results will be modeled
" to use the TEM to isolate and identify the location of the actinides associated with the
colloid minerals.
" model our experimental results to determine the long term behavior of Pu in
groundwater These results will feed process level models.
