| Abstract: | Summary A preconcentration technique involving anion-exchange in thiocyanate media has been developed for the determination of traces of bio-significant and biofunctional elements. The procedure is applied to the analyses of NBS standard reference materials as well as environmental reference materials of NIES (The National Institute of Environmental Studies, Japan Environmental Agency). The results are quoted for vanadium, cobalt, copper, zinc, and cadmium. |
