ICP-MS测定岩盐中痕量铷和铯

Determination of Trace Amounts of Rb and Cs in Rock Salt by ICP-MS

样品经水溶解后,选铑做内标,用ICP-MS测定岩盐中痕量铷和铯,回收率在96.0%—104.0%之间。

The rock salt samples were dissolved in water,Rh as internal standard,and trace amounts of Rb and Cs in rock salt were determined by ICP-MS.The recovery is 96.0%—104.0%.
