本文介绍了用离子交换法分离和测定反应堆一回路冷却水中主要活化腐蚀产物。被分离的主要核素是:~(59)Fe、~(58,60)Co、~(54,56)Mn、~(51)Cr、~(65)Zn、~(64)Cu、~(24)Na等。该方法的原理是利用各核素在树脂上的交换势不同和某些络合剂在一定pH下和核素的络合能力的差异来达到阳柱上组分离。然后,再用在不同浓度盐酸介质中各核素形成阴离子的能力的不同,通过阴柱分离,达到单个核素分离。方法回收率为83—95%,精度为1.6—6.0%。 用此方法对实际水样中的活化腐蚀产物进行分离和测定,结果是满意的。
This paper describes the use of ion exchange separation and determination of primary reactor primary cooling water corrosion products. The main radionuclides that were separated were ~ (59) Fe, ~ (58,60) Co, ~ 54,56 Mn, ~ 51 Cr, ~ 65 Zn, ~ 64 Cu, 24) Na and the like. The principle of this method is to use the difference in the exchange potential of each of the nuclides on the resin and the difference of the complexing ability of some complexing agents and nuclides at a certain pH to achieve the separation of the upper positive column. Then, with different concentrations of hydrochloric acid medium, the ability of each nuclide to form anions is different, and the single nuclide separation is achieved through the separation of the pillars. The recovery rate was 83-95% with the precision of 1.6-6.0%. The method is used to separate and determine the activated corrosion products in the actual water samples. The results are satisfactory.
