- Methods used for the determination of copper content in pyrotechnics are mostly based on traditional chemical method, which is lengthy and cumbersome. If inductively coupled plasma emission spectrometry or atomic absorption spectrometry are used to determine the copper with high content,the sample solution must be highly diluted,and it mustproduce errors in measurement and calling into question the reliability of the data.The method mentioned in this paper is about the determination of copper content in pyrotechnics used for fireworks and firecrackers based on energy dispersive X-ray fluorescence spectrometry by controlling matrix effects between elements.Using samplesolution of pyrotechnics in specific concentrates,the copper content can be determinedby the specificcalibration curve established with an intensity calibration.This method can provide high accuracy and good precision in a short time with a simple process byefficiently controlling the matrix effects.It can fully meet the requirements forthe determination of copper in pyrotechnicsused for different kinds of fireworks and firecrackers around the world,and ithas good generalization and practicability.The average recovery of the method can be97.87%~99.78%, allowing for a difference of 0.5%.
