I'm teaching a unit on EDTA and its myriad uses in chemistry. I read somewhere about why EDTA is often present in the cleaning solution used to sponge up spills of low-level radioactive aqueous solutions. Two questions:
1) How/why does EDTA enhance the cleanup from a chemical perspective? I'm sure it has to do with the high Kf value for complexation, but I'd love a confirmation.
2) What is done with the contaminated solution after sponging off the area?
