摘要：
Sorption of Pu and Np on chitin, chitosan, and chitin-containing materials from strongly alkaline (1-4 M NaOH) solutions was studied under the static and dynamic conditions in the presence of large amounts of NaNO3. The Pu(IV) distribution coefficient (K-d) between the solutions with the NaOH concentration ranging from 1 to 4 M and different chitin-containing sorbents varies from 3000 to 6000 cm(3) g(-1). The K-d of Np(V) with different sorbents decreases from 2000-4000 to 600-1200 cm(3) g(-1) with increasing NaOH concentration.
