摘要
用等离子体质谱法,采用ρ(9Be)=25ng/ml的2%HNO3溶液作为内标溶液在线加入,直接测定饮用天然矿泉水中的硼酸。方法检出限为0.026μg/L,相对标准偏差(RSD,n=12)为8.52%。该方法简单、快速、准确,适用于饮用天然矿泉水中硼酸的测定。
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.
