日本介绍了用电感耦合等离子体质谱法(ICP-MS)同时测定高纯铝中的超微量铀和钍的灵敏法。用10%v/v 的三丁基磷酸酯环已烷溶液萃取法,使铀和钍与含10mol dm~(-3)盐酸的试液分离。用内标法进行
Japan introduced the sensitive method for simultaneous determination of ultra-trace amounts of uranium and thorium in high purity aluminum by inductively coupled plasma mass spectrometry (ICP-MS). Uranium and thorium were separated from the test solution containing 10 mol dm ~ (-3) hydrochloric acid by 10% v / v tributylphosphate cyclohexane extraction. Using internal standard method
