“…[1][2][3] 86 Y as a widely used surrogate for 90 Y in PET imaging and cancer radiotherapy is produced from nat Sr, 4,5 however, it should be free from nat Sr. A highly selective and rapid method for the separation of radioyttrium is required for its use as a nuclear medicine. Several methods for the preconcentration and separation of Y(III) have been used, based mainly on precipitation, 6 ion exchange, 7 liquid extraction 8 and solid phase extraction (SPE). 9,10 SPE has become one of the widely used preconcentrative techniques for trace analysis due to the higher enrichment factors obtained, low organic solvent consumption, simplicity, absence of emulsions, eco-friendliness, ease of automation, speed and low cost.…”

“…Examples include extraction chromatography [15][16][17], cation-exchange chromatography [18][19][20], and displacement chromatography. For lanthanide separations, Strelow and Victor [21] and Spedding et al [2] used cation-exchange chromatography. Displacement chromatography was investigated with a mixture of Nd and Sm as a nonradioactive simulant to represent the Am/Cm separation problem [22].…”

Lanthanide separation by simulated moving-bed chromatography was studied as a model system for separating lanthanide fission products and minor actinides from used nuclear fuels. The simulated moving-bed system was modeled for a tertiary pyridine anion-exchange resin supported on silica particles as the stationary phase and a mixture of methanol and 1 M nitric acid as the mobile phase. Pulse injection tests using a single packed column were used to obtain chromatographic parameters for mathematical modeling of the simulated moving-bed system. Higher concentrations of methanol improved the separation, but the chromatograms showed evidence of nonlinearity of the isotherms. The mathematical model of the simulated moving-bed process predicted a production rate of purified samarium and neodymium at 118 g solute/L resin/day and a purity of 99.5%. The optimal methanol ratio for the production rate for various product purities was determined from the model. The excellent separation of Nd and Sm suggests that the simulated moving-bed system could be applied to the separation of minor actinides such as americium and curium.

High performance thin layer chromatography (HPTLC) has been used for the simultaneous determination of pentaerythritol tetranitrate (PETN) and 2,4,6-trinitrotoluene (TNT). With this aim, the spots were developed on silica gel 60 F 254 layers with petroleum ether -acetone (2 : 1 v/v). Both PETN and TNT compounds were separated from other constituent materials, and were developed at the same speed, by this solvent system. Then ultraviolet (UV) spectra of these materials were recorded with TLC-scanner3 of CAMAG Company, and partial least squares regression-2 (PLSR-2) method was applied for the calibration and quantitative determination of these materials. The figure of merit (FOM) of this method was determined, and the method was applied for the analysis of an artificial sample.
