摘要：
A spectrophotometric method has been proposed for the sequential determination of molybdenum and tungsten in silicate rocks. The procedure proposed has been successfully used to determine molybdenum and tungsten in granite. The results show that this method can accurately determine molybdenum and tungsten down to the mug g-1 and sub-mug g-1 level with relative standard deviations of 1% and 3.5%, respectively.
