Abstract

Methods used for the determination of potassium content in potassium perchlorate 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 potassium 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 potassium content in potassium perchlorate used for fireworks and firecrackers based on energy dispersive X-ray fluorescence spectrometry by controlling matrix effects between elements.Using samplesolution of potassium perchlorate in specific concentrates,the potassium 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 potassium in potassium perchlorateused for different kinds of fireworks and firecrackers around the world,and ithas good generalization and practicability.The average recovery of the method can be96.49% 99.63%, allowing for a difference of 0.5%.
