摘要: Dissolved nuclear wastes (Am, Cm, Pb, Np, Pu, Ra, Th, and U) can be affected by the composition of natural waters. Natural waters have different values pH, composition, ionic strength, temperature, pressure. The solubility these elements in determined experimentally or modeling. Since direct measurements are not presently available for many metals interest, it is important to develop methods that used estimate solubilities known composition. In this paper, one approach using Pitzer’s equations discussed. For some (i.e., Pb effect directly calculated existing data. While, others Am Cm) limited data must use model compounds (rare earths) as analogs. Fe(III) seawater a function pH demonstrate how used. has also been speciation number radionuclides WIPP brines.
