Research on rapid qualitative detection of antimony in pyrotechnic powder used for fireworks and firecrackers
This study discloses a method for quickly qualitatively detecting the antimony element for fireworks and firecrackers based on energy dispersive X-ray fluorescence spectrometer(EDXRF),including the following steps: preparation of samples,establishment of detection methods,determination of the characteristic line fluorescence intensity values of Sb element in samples.The method of the study has the advantages that:(1)the method is simple to operate,and the method can be repeatedly called for testing.Only one new test method needs to be built before the sample test.After the method is established,the test can be repeated at different times without re-establishing the test method for each test.After the first establishment of the new test method,the entire test process only includes three steps: sample preparation,sample loading into the sample cup and on-board testing.(2)The detection period is extremely short.After the sample is prepared,the entire measurement process takes only about 2 minutes.(3)Labor intensity is very low and the requirements for operators are not high.(4)The method has good stability,good repeatability and high credibility.
