| Abstract: | In this paper,the Graphite Furnace Atomic Absorption Spectrometry(GFAAS) was applied to the determination of molybdenum in lixiviated solution discharged from plants of producing Fe and Mo.Under optimized conditions,the higher analytical sensitivity and good precision were obtained.A good linearity for determination of molybdenum in samples was found in the range 2.4～60 μg/L,with a correlation coefficient of more than 0.999.The obtained detection limit was 0.6 μg/L.Furthermore,this proposed method has been used for determining of molybdenum in lixiviated solution with satisfiable results. |
