The invention provides a method for analyzing and detecting lead metal elements in solid food samples, comprising: (1) dissolving the solid food samples by using a hydrophilic ionic liquid; (2) adding deionized water to precipitate cellulose, and filtering (3) The lead content of the aqueous solution of hydrophilic ionic liquid was detected by graphite furnace atomic absorption spectrometry. The method has the advantages of high sensitivity, strong universality and simple operation. |
