Abstract
Ten sets of experiments with different settling times were conducted to investigate the effect of settling time on the adsorption of 137Cs in seawater onto ammonium phosphomolybdate (AMP). The weight yields of AMP and 137Cs yields in all groups were generally higher than 90%. The average weight yields of AMP in each group varied from 91.8 ± 0.5 to 95.9 ± 0.6% (1 SD), and the average 137Cs yields in each group varied from 88.3 ± 3.0 to 97.8 ± 3.7% (1 SD). The results showed that equilibrium between Cs and AMP is established immediately after the addition of stable Cs carrier and AMP, implying that the solution could be filtered immediately after the coprecipitation forms. IAEA seawater proficiency test exercises also confirmed that the AMP precipitate does not need to be treated statically in the case of 2 g AMP and 3.7 mg Cs carrier in a seawater sample solution. The modified AMP preconcentration method simultaneously meets the requirements of routine and nuclear emergency monitoring of 137Cs in seawater.
