英文摘要A sensitive analytical method for determination of Pu-239 and Pu-240 in environmental water samples was developed. By co-precipitation of plutonium with Ti (OH)(3) followed by separation of plutonium using extraction chromatography with TEVA resin, a recovery of more than 80% 14 plutonium and a decontamination factor of 1. 3 x10(5) for uranium were achieved. A triple quadrupole inductively coupled plasma mass spectrometry ( ICP-MS ) method with dynamic collision/reaction cell was used for measurement of plutonium isotopes. By using NH3-He double gasses as collision/reaction gas, (UH+)-U-238-H-1 ion interference to Pu-239 was significantly suppressed and the final abundance sensitivity of U-238 to m/z =239 was reduced to <1 x 10(-11), meanwhile the sensitivity of Pu-239 was improved to 990 cps/ ( pg/g) . For 20 L of water sample , the detection limits of the method for Pu-239 and Pu-240 reached 1. 28 x 10(-7) Bq/L and 1. 38 x 10(-7) Bq/L, which enabled accurately determination of Pu-239 and Pu-240 in normal environmental water samples. The developed method was successfully applied to determine Pu-239 and Pu-240 in the spiked water and real environmental water samples. The results indicated this method was reliable and could be practically applied.
