在典型的近场和远场化学环境中，研究了钚的溶解和吸附。在pH 11-12的近场范围内，该物质的表观溶解度极限约为10- 10 M。吸附到所有的固相研究通常是高的，分配比，RD，范围从102至106毫升g-1的值。这些RD值随相分离技术、初始浓度和水岩比而变化。RD的这种变化部分归因于在所考虑的所有实验条件下形成大的聚合物（或团聚）物种。
The solubility and sorption of protactinium were studied for typical near-field and far-field chemical environments. The apparent solubility limit of protactinium in the near field at pH 11–12 was about 10–10M. Sorption on to all of the solid phases studied was typically high, with values of the distribution ratio, RD, ranging from 102 to 106 ml g–1. These values of RD varied with the phase separation technique, the initial concentration of protactinium and the water to rock ratio. This variation in RD was in part attributable to the formation of large polymeric (or agglomerated) species under all the experimental conditions considered.
