Pyrrolidone derivatives of N-propyl-2-pyrrolidone (NProP) and N-butyl-2-pyrrolidone (NBP) are being studied for selective precipitants for uranyl ion. Structural analyses of UO(NO)L [L=NProP or NBP] was carried out using X-ray diffraction method. Relationship of the structure of the complex and the precipitation ability of the reagent are also discussed considering results of Raman spectrum measurement.
