Abstract

Inductively coupled plasma optical emission spectrometric approach(ICP-OES) is used to determine the chromium content in pyrotechnics used for fireworks and firecrackers. Element of chromium is commonly found as impurity in chemical materials used for pyrotechnics in fireworks and firecrackers. Statistical analysis shows that chromium content in pyrotechnics is below 5%.Concept of this method: considering the weight of the sample is 400mg,constant volume is 0.5L and the concentration of chromium is below 40mg/L in sample solution, the determination scope of the method for the chromium content would be between 5%.Further experiments proved that the fitting correlation coefficient of chromium calibration curve is 0.9995 or higher, recovery is 93.96%-100.49%.The allowable differential value is 0.4% between two single tests under repeatable conditions. This method can completely satisfy the requirements of the fireworks and firecrackers industry with high accuracy and good precision.
