Description

A radiochemical separation method has been developed to determine the elements W, Cd, Cr, U, Th e Co in three biological materials of botanic origin used as SRM's: Peach Leaves, Apples Leaves and the new proposed material Spinach. The aim was to obtain more information for these elements whose values are not yet determined or are given only as suggested values. The radiochemical procedure was based on chromatographic separation using resin Chelex 100 in H Ac 0.1 M-N H4 Ac 0.1 M at pH 4.8. All the experimental data e results obtained are described and compared with the literature values. (author). 10 refs, 4 tabs
