【Abstract】 According to the theory of evaluation and express of uncertainty in measurement, the uncertainty of fluoride in water was determined by using ion analyzer, and the results show that the expanded uncertainty of fluoride in water U%-{95}% is 0.31 mg/L, %v%-{eff} is 174. It provides references for the relational departments.更多还原
