Preparation and characterization of poly nano-cerium chloride for Mo production based on neutron activation reactions.

Different molar ratios of the cerium trichloride heptahydrate to isopropyl alcohol (1:2, 1:3 and 1:5) were studied to choose the optimum ratio, and studied the reaction temperature effect (80, 90 and 100 °C) to determine the optimum temperature for the preparation of poly nano cerium chloride (PNCC). The PNCC-1 was selected among the prepared PNCC batches based on the Mo sorption properties that confirms the feasibility of using it as a novel effective sorbent material. The structural properties and chemical composition were studied using different techniques and devices such as EDX, XRD, FESEM, FTIR, TGA, and DTA.

Radiochemical separation of reactor produced Sc-47 from natural calcium target using Poly(acrylamide-acrylic acid)/multi-walled carbon nanotubes composite.

Poly (acrylamide-acrylic Acid)/multi-walled carbon nanotubes composite [P(AAm-AA)/MWCNTs] was prepared by gamma radiation to initiate the copolymerization of AAm and AA onto MWCNTs surface. The structural characteristics were confirmed by FT-IR, SEM, XRD, TGA and DTA. The particle size distribution was determined by dynamic light scattering (DLS).

Preparation and characterization of zirconium silicoW-tungstate as a base material for W/Re generator.

Zr:W:Si. The optimum gel was prepared using the molar ratio 1:1:7 at pH 8. The ZrSiW gel was investigated by FTIR, XRD, thermal analysis (TGA and DTA), FESEM, XRF, and NAA.
