Abstract
ICP-MS was applied to the direct determination of trace molybdenum in natural mineral water for drinking. The recovery was 94.5%- 110%,the detection limit was 0.007 μg/L,and the relative standard deviation (RSD)was less than 3.8%. Enjoying the advantages of low interference,relatively simple spectral line,low detection limit,wide dynamic linear range and rapid operation,the method can be used for the determination of trace molybdenum in natural mineral water for drinking.
