| Abstract: | Boric acid in natural mineral water for drinking was determined directly by ICP-MS, with 2% HNO3 of p （gBe） = 25 ng/ml added on-line as the internal standard solution. The detection limit was 0.026μg/L, and the relative standard deviation （RSD, n= 12） was 8.52%. Being simple, rapid and accurate, the method is suitable for the determination of boric acid in natural mineral water for drinking. |
