Laser-Induced Fluorometry for Rapid Determination of Micro-levels of Uranium in Geochemical Materials |
| |
| Abstract: | A laser-induced fluorometric method is described for rapid determination
of micro-level uranium in geochemical materials with Modified Anti-interfer-
ence reagent for uranium (MAFG).The method is characterized by direct using
of the residual solution used in ICP-AES for simultaneous mufti-element de-
teimination,therefore no prior sample preparation is required. A simple method
for correcting the inner filter effect of iron is proposed. The detection limit of
the method is 0.05 ug/g. The relative standard deviation for seven replicate
determinations of the standards GSD are ranged from 2.2-7.1%. |
