Abstract: In terms of the analysis result accuracy evaluation of gold and impurity elements in 999 ‰ gold jewelry,and referring to the technical requirements of accuracy test,the paper proposed the workable judgment ideas which are easy to implement based on practice.Taking the analysis data in ICP-OES test report as the statistical analysis samples,the paper discusses the distribution rules of impurity elements,and the 4 elements of Ag,Cu,Zn and Fe,which account for more than 95 % of the total amount of impurities,were summarized as the main impurity elements.And it is clearly pointed out that Ag is an important factor affecting the accuracy of test results.At the same time,hydrochloric acid is a key factor affecting silver analysis and determination.The research provides technical support to ensure and improve the accuracy of the destructive analysis of 999 ‰ gold jewelry.
