Use of selectively coated MAG*SEP{sup SM} particles for improved radionuclide field sampling

PDF Version Also Available for Download.

Description

The Savannah River Technology Center is evaluating a new field sampling methodology to more easily determine concentrations of radionuclides in aqueous systems. The new methodology makes use of the process developed by Selective Environmental Technologies (Selentec) whereby selective ligands are attached to particles with a ferrous metallic core (MAG*SEPsm). The particles retain the properties of the ligand and are also attracted to a magnet. By appropriately choosing the ligand on the particles, only the analyte of interest will be extracted when using the developed field sampler. The particles are separated from the aqueous sample by pumping the water past a ... continued below

Description

The Savannah River Technology Center is evaluating a new field sampling methodology to more easily determine concentrations of radionuclides in aqueous systems. The new methodology makes use of the process developed by Selective Environmental Technologies (Selentec) whereby selective ligands are attached to particles with a ferrous metallic core (MAG*SEPsm). The particles retain the properties of the ligand and are also attracted to a magnet. By appropriately choosing the ligand on the particles, only the analyte of interest will be extracted when using the developed field sampler. The particles are separated from the aqueous sample by pumping the water past a specially designed magnet. The particles with attached analyte can then be returned to the lab for quantification. Tests have been completed characterizing two sets of prepared particles. One set was prepared to extract technetium from aqueous systems, the other to extract cesium. Initial tests were performed on spiked samples in the lab, with later tests demonstrating the applicability to field sampling. Field sampling procedures have been developed for a sample size of one liter or for 20 liters. Field samples were collected from around the Savannah River Site, from the Atchafalaya River near New Orleans, and from the Ob River in Russia. A distinct advantage of this new sampling technique is the lack of interference caused by high suspended particulate loads.
