A METHOD FOR DETERMINATING STRONT1UM-90 IN SEAWATER
Abstract:
The analytical method for strontium-90 in seawater has been studied with isotopes 90Sr as tracer. The relationships among the amount of Sodium Carbonate, setting time, temperature and recovery have been defined. The amounts of Sodium Carbonates varied from 3 to 12 gram per liter of seawater. When carbonate precipitant is heated, the time of settlement will be shortened from 24 to 1 hour. The recovery is about 90%.
