钼铁厂固体废物浸出液中钼的测定

Determination of Molybdenum in Lixiviated Solution of Solid Residue from Plants

用石墨炉原子吸收光谱法测定钼铁厂固体废物浸出液中的钼,当选择合适实验条件的情况下,钼的测定灵敏度较高,校准曲线的相关系数大于0.999,精密度较好,方法的检出下限为0.6μg/L,定量测定范围2.4～60μg/L,测定结果令人满意.

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.
