Abstract:
The method and uncertainty evaluation of spectrophotometric determination of silicic acid in geothermal mineral water were studied. The mathematic model of uncertainty of the method was established. The expanded uncertainty of the method was acquired. The content of silicic acid in Xixi geothermal mineral water in Hezhou City, Guangxi Province was determined. At the same time, in order to verify the reliability of the method, a national standard substance for the analysis of silica composition in water (GBW(E)080236 standard value and extension uncertainty: 20.0±0.8 mg/L, k＝2) was determined. The results showed that the content and expansion uncertainty of silicic acid in Xixi geothermal mineral water in Hezhou City were 125.3±13.0mg/L, k＝2. The determination result of the standard substance was 20.3 mg/L, which was consistent with the standard values.
