摘要
建立了全谱直读等离子体光学发射光谱(ICP-OES)法测定饮用天然矿泉水中偏硅酸(H2SiO3)的新方法,优选 了试液介质和仪器条件。方法简单、快速、灵敏度高,偏硅酸(H2SiO3)的捡出限为0．09mg/L。相对标准偏差小于1％,用于 饮用天然矿泉水中偏硅酸的测定,取得了满意的结果。
A new method of determining metasilicic acid （H2SiO3） in natural mineral water for drinking by ICP-OES is established. The medium of solution and measurement condition are optimized, Being simple, rapid and highly sensitive, the method is featured by the detection limit of 0.09 mg/L and the relative standard deviation less than 1%. It has been applied to the determination of metasilieic acid （H2SiO3） in natural mineral water for drinking with satisfactory results.
