The uranium contents of sea water, brine and bittern were determined fluorophotometrically by fusion method after extraction with ethylacetate.
Sample solution was filtered by membrane filters (average pore, size, 0.4μ).
Uranium contents of both soluble and particulated parts were determined.
The range of uranium contents dissolved in sea water, brine and bittern were from 1.4 to 2.5μg/L (average 1.8), from 6.0 to 150.8μg/L (average 29.7), from 52.8 to 154.4/μg/I.,(average88.6) respectively, and these values showed that the uranium in sea water was concentrated in bittern remarkably.
Uranium contents in particulated matter in bittern varied from 24.5 to 59.2μg/L (average 39.7) and these values were found to be about 1/2-1/3 of the total uranium contents.
