摘要
原矿样品经过氧化钠熔融,三乙醇胺提取,在pH=2~3的酸度下,用PMBP-苯萃取钍,再用4 mol/L盐酸反萃取使钍与干扰元素分离。进行ICP谱仪测定钍的含量。
The samples were extracted with sodium oxide and triethanolamine. The thorium was extracted with PMBP-benzene and then extracted with 4 mol/L hydrochloric acid to separate the thorium from the interfering elements. Determination of thorium content by ICP spectrometer.
