“…Furthermore, negligible or no adsorption is observed for actinides in the trivalent oxidation State. Therefore, these adsorption behaviours are used in most analytical procedures in order to separate plutonium from americium [23]. In Oxalate medium, the Charge of the predominant species in Solution might explain these differences.…”

A new method for thin radioactive source preparation is presented based on two distinct steps: (1) -preparation of a thin film (area of several cm^) as a source support and (2) -incorporation of radioactive Clements by an ion exchange mechanism. The asources are prepared by simply immersing the specially prepared supports into solutions containing actinides. The thin films were obtained through electropolymerization of pyrrole monomers functionalized by anion-exchange groups. The physicochemical Parameters of the films such as deposit weight, thickness and roughness have been studied. The ion exchange characteristics of the polymer films are very similar to those of classical anionexchange resins. The Optimum actinide (uranium(VI), plutonium(IV) and americium(III) incorporation conditions (i.e. selection of the complexing agent and retention yields) have been investigated in detail.

A review is presented of the nitrate-solution, anion-exchange technique for the purification and concentration of plutonium, emphasizing the chemical and chemical engineering nature of the process. After a brief introductory chapter the next two chapters review the fundamentals of ion exchange and the solution chemistry of plutonium. The basic chemistry of the nitrate, anion exchange of plutonium is described in Chapter IV. The final two chapters deal with the applied process.

Determination of In and Ga in plutonium oxide matrix by ICP-AES after chemical separation

An analytical method was developed for the determination of indium and gallium in plutonium samples. A solvent extraction technique was employed by using 30% TBP in CCl 4 for the quantitative separation of plutonium from the sample solution and subsequent determination by radial inductively coupled plasma atomic emission spectrometry (ICP-AES). The quantitative recovery of In and Ga in the separated samples was confirmed from radiometric/tracer studies. Recording of spectral profile at 303.396 nm for In and 403.298 nm for Ga has clearly indicated that the determination of Ga and In at lower concentrations will be affected by the presence of significant amounts of residual Pu in the aqueous phase due to spectral interference. These elements can be determined from ppm to % levels by proper dilution with 1 M HNO 3 and appropriate (100 mg and 1 g) sample size. The analytical range obtained for Ga and In was 0.1-1000 µg/mL and 0.05-500 µg/mL respectively by ICP-AES. Synthetic samples of plutonium containing indium and gallium in the range of 50-20 000 ppm were analyzed.
