THE DETERMINATION OF ELEMENTS Li,Na,Fe AND Sr IN THE LEACHING SOLUTION FOR VITRIFIED WASTE FORM BY ATOMIC ABSORPTION SPECTROPHOTOMETRY

The determination methods of elements Li,Na,Fe and Sr in leaching solution for simulated vitrified HLW form by atomic absorption spectrophotometry are reported. The optimized operating parameters of individual elements are determined. The effects of interfering elements on object element are studied. The recovery rate of object elements is measured to be 93% -125%.
