Abstract
An extraction chromatographic resin containing the acidic chelating organophosphorus extractant, Dipex®, sorbed onto an inert polymeric substrate has been evaluated for the separation of beryllium from a wide range of elements. The elements selected comprise those which can interfere with the determination of beryllium by inductively coupled plasma‐atomic emission spectroscopy (ICP‐AES) and matrix elements which commonly occur in environmental and industrial samples. Based on batch uptake measurements, a method that separates beryllium from all potential ICP‐AES spectral interfering elements using a single extraction chromatographic column is outlined. The chromatographic parameters of the separation method have been optimized using simulated samples generated using the digestion process employed in beryllium analyses by the Y‐12 National Security Complex and simulated ground water samples.
