| Abstract: | A method was studied for evaluation and calculation of uncertainty in determination of iron in zinc metal by sulfosalicylic acid spectrophotometry The determination content for 0 0012% iron is between 0 00115% and 0 00125% at the 95% confidence level The results,for evaluation and calculation of type A uncertainty and type B uncertainty,show that the uncertainty of this method mainly roots in type A uncertainty |
