Study on analysis method of tritium in seawater

The reclamation rate formula for concentrating tritium by the addition of "regular and quantitative aqueous sample" is advanced.
Effects of different adding modes on reclamation rate and the reclamation rate reappearance are studied; and the analytic program of tritium in seawater is also proposed.By using Fe-Ni electrodes and the electrolysis temperature of 2±0.5℃,β value reaches 20.Reclamation rates reach 83% and 76% when 250 cm³ and 500 cm³ seawater is concentrated to 8 cm³.
The relatively appropriate toluene/Trition ratio for counting aqueous sample under the normal temperature is proposed.
The computer program of different addition electrolytic concentrations for measuring tritium is coded,and the tritium data base is established.
