Sažetak
A voltammetric method is reported for the determination of low uranium concentrations in natural waters. A very strongly adsorbed mixed complex of uranyl ion with 2-thenoyltrifluoroacetone and tri-n-butyl phosphate is applied. Synergic adsorption is obtained compared with the adsorption obtained with either ligand alone. In 0.55 mol dm−3 sodium chloride, the detection limit was 10−10 mol dm−3 uranyl ion after accumulation for 10 min at −0.1 V vs. Ag/AgCl. For the natural level of uranium in sea water (about 10−8 mol dm−3), accumulation for 2 min was sufficient.
