对4-氨基安替吡啉三氯甲烷萃取分光光度法测定的地下水中挥发酚不确定度的评定
Uncertainty evaluation for the determination of phenol in groundwater samples by 4-amino antipyrine chloroform extraction spectrophotometry
摘要
Abstract
The measurement uncertainty of the analytical results of phenol in groundwater samples by 4-Amino antipytine chloroform extraction spectrophotometry was evaluated using continuous propagation model of uncertainty. The standard uncertainty of a ground-water sample was evaluated and the expanded uncertainty was calculated, which shows the measurement is credible. The results show that the uncertainty caused by the curve fitting and the sample preparation makes a relatively great contribution to the expanded uncertainty.关键词
