Multielement analysis by sequential instrumental and radiochemical neutron activation

Conference ·
OSTI ID:7349433
We measured 37 elements in six USGS geological samples and one NBS orchard leaf (OL) sample, using sequential INAA and radiochemical group separation coupled with high resolution and high efficiency Ge(Li), and Ge(Li) with anticoincidence shields. The elemental concentrations in these samples vary over three orders of magnitude. Our results agree very well with the reported values. Our REE values in PCC-1 are 2 to 4 times lower than the reported values. Precise REE patterns are defined in USGS samples, which are characteristic of the total rock types. The REE pattern in OL is identical to the mineral apatite, suggesting that the uptake of REE trace elements by plants from soil is perhaps dominated by accessory mineral such as apatite, or plants take up the REE from bulk soil in a preferential manner as a smooth function of the REE ionic radii.
