Detection method of lead content in triacetin

The invention discloses a detection method of lead content in triacetin. The detection method is characterized in that a sample is diluted through absolute ethyl alcohol at the pre-processing stage, a standard adding method is adopted, and an air oxidation step is added between the drying step and the ashing step in the atomic absorption spectrometer heating process, thus the sample can be directly fed and detected, and the content of lead in triacetin can be quickly and accurately detected. Compared with the conventional electric hot plate digesting and microwave digestion pre-processing, the detection method disclosed by the invention has the advantages that little loss of the element to be detected is caused during direct feeding, the operation is easy, and poisonous and harmful chemicals are not used in the experimental process, so nearly no harm is brought to an operator. According to the detection method of the lead content in triacetin, after detection adopting the optimized related heating processes, ashing temperature and atomizing temperature of the atomic absorption spectrometry based on the characteristics of the triacetin material, a matrix modifier is adopted and used for eliminating the interference, thus high recovery rate is realized, and the detection result is accurate.
