Abstract: According to the national food safety standards, the pretreatment methods for detecting lead, total arsenic, total mercury, and chromium are not uniform, and unified processing and testing cannot be achieved. A microwave digestion method is established to digest dairy products, and the digested samples can also meet the requirements of graphite furnace atomic absorption. Spectrometric detection of lead, chromium and atomic fluorescence spectrometry to detect total arsenic and total mercury. The test verification results show that the samples treated by microwave digestion method can be used for the detection of lead, total arsenic, total mercury and chromium simultaneously. Digestion method for the determination of lead, total arsenic, total mercury and chromium in dairy products has relatively small deviation and high recovery rate. Satisfactory data parameters are obtained and the detection data is accurate. The lead, total arsenic, total mercury and chromium in the sample are greatly shortened Detection time.

Key words: microwave digestion, lead, arsenic, mercury, chromium, dairy products
