Sorption recovery of plutonium by POLIORGS fibrous complexing sorbents

The sorption recovery of plutonium and other radionuclides by fibrous compl exing sorbents from salt solutions (neutral and acidified with nitric acid) was studied. Plutonium, americium, uranium, thorium, and europium are reco vered from neutral salt solutions by POLIORGS 33 sorbent containing amidoxi me and hydrazine groups, and plutonium is separated from multicomponent sal t solutions acidified with nitric acid on the POLIORGS 33A sorbent (modifie d with arsenate In). Plutonium can be selectively recovered and separated f rom the other lanthanides(III) and actinides(III) with POLIORGS 33A.
