Determination of Na and Fe in High Level Liquid Waste by Closure Atom Absorption Spectrum(In Chinese)

A method of measuring Na and Fe in High Level Liquid Waste(HLLW) by gloved fire atom absorption spectrometry was established.High Level Liquid Waste(HLLW)culd be directly measured.The stabilization of the method is good.The operation is convenience and fast.The precission(RSD) of Na and Fe is better than 2% and 4% respectively.The standard added-recovery for Na and Fe is 98.7% and 96.8% respectively.The results are well agreed with that obtained by other method and passed through F test.
