硫酸锰中微量Gd,Sm,Dy,Eu的离子交换分离ICP-AES测定
DETERMINATION OF TRACE Gd, Sm, Dy AND Eu IN MnSO4 BY ICP-AES AFTER SEPARATION WITH CATION EXCHANGE METHOD
【摘要】 <正> 一、前言在用锰浴法绝对测量放射性中子源(Am-Be)的强度中,为了准确计算中子源的强度,需要对硫酸锰中热中子吸收截面较大的Gd,Sm,Dy和Eu等稀土元素的含量进行测定,以
【Abstract】 A method for determination of trace Gd, Sin, Dy, Eu in MnSO4 is described. The manganese is separated from rare earth elements by cation exchange resin with 2 mol/l HCl as eluent. The concentration of rare earths is determined by ICP-AES. With a sample of 50mg , the determination limit of Gd, Sm is 0.4×10-6, Dy, Eu is 0.08×10-6, the recovery is in the range of 88%~105%, the relative standard deviation (RSD) is less than 11%.
