摘要
本文提出了一种适用于测定化探样品中痕量钨和钼的分析方法。在硫氰酸盐的存在下,用甲基异丁酮(MIBK)萃取钨和钼的硫氰酸络合物,然后直接将有机相导入ICP进行测定。方法的实际测定下限为W.0.01μg/ml,Mo.0.005μg/ml。
The proposed method is applicable to the determination of trace amounts of tungsten and molybdenum in geochemical samples. Tungsten and molybdenum are complexed with thiocyanate, it is extracted with MIBK and followed by determination with ICP-AES by introducing the extract directly into plasma. This method is simple and precise. Determination limit of the method is W 0.01μg/ml, Mo 0.005μg/ml.
