Uncertainty Evaluation on Determination of Aurum in E-waste by ICP-AES

摘要

E-waste gold element content and the main source of content uncertainty is the use of inductively coupled plasma atomic emission spectrometry (ICP-AES) analysis determination. This article takes aurum as an example to analyze, compound and calculate five uncertainty components in resolving process, such as weighing samples, constant volume, standard preparation of measurement, curve fitting, and repeatability of instrument measurement to the influence of the result.
