钯属于铂族贵金属,具有很高的经济价值,应用也十分广泛,如在催化剂或电镀上的应用。而钯在地壳中的含量很低,只有10 ng/g。准确测定痕量钯的含量是非常重要的,且在某些情况下需要测定钯的同位素比值。而在用ICP-MS测量岩石中痕量钯同位素比值时存在着~(106)Cd、~(108)Cd、~(110)Cd等核素的干扰,难以准确测定,所以需要建立岩石中痕量钯的分离方法。欲准确测定岩石中痕量钯的含量或其同位素
Palladium is a platinum group noble metal, with high economic value, the application is also very extensive, such as in the catalyst or plating applications. The amount of palladium in the crust is very low, only 10 ng / g. Accurate determination of the amount of trace palladium is very important, and in some cases the need to determine the palladium isotope ratio. However, the interference of ~ (106) Cd, ~ (108) Cd, ~ (110) Cd and other nuclides in the determination of trace palladium isotope ratio in rock by ICP-MS is difficult to determine accurately, so it is necessary to establish the trace of rock Amount of palladium separation method. For accurate determination of trace amounts of palladium in rocks or their isotopes
