3.1 Principle
A certain volume of water samples, after adding acidified with nitric acid. Carrier added ferric chloride and ammonium chloride, pH was adjusted with ammonia, uranium, thorium and enriched with hydrogen
Oxide form precipitation. The precipitate was dissolved with concentrated nitric acid to prepare a solution to the column, through the P350 extraction chromatographic column, separated from other interfering elements,
Purification of uranium and thorium. With hydrochloric acid elution thorium, uranium and then eluted with sodium fluoride. Electrodeposition process for producing thorium and uranium α source. Respectively α spectrometer
The measurement of uranium and thorium isotopes α spectrum curve, and calculated the ratio.
3.2 Reagents
