Abstract:

In order to improve the reliability of gold measurement,taking Evaluation and Guidance of Measurement Uncertainty as a guide,we systematically analyzed uncertainty on determination of gold in gold ore by atomic absorption spectrophotometry after activated carbon adsorption.Analyzed on sources of uncertainty was carried out in this article,including weighing mass of the sample,calibration solution preparation of gold,volume of the sample solution,calibration curve fitting,measurement repeatability and so on.The components of measurement uncertainty were used to establish mathematical model to determine primary factor of measurement uncertainty,and combined standard uncertainty and expanded uncertainty are evaluated.The combined standard uncertainty the expanded uncertainty is 0.52 g/t and 1.04 g/t respectively.It showed that weighing mass of the sample has the most significant effect on relative standard uncertainty.

Key words: uncertainty evaluation, activated carbon adsorption, Atomic , Absorption Spectrophotometry, gold
