The invention relates to the technical field of detection, and particularly relates to a method for determining the lead content in an industrial hemp processing extract through microwave digestion-graphite furnace atomic absorption. According to the method, after an industrial hemp processing extract sample is subjected to microwave digestion treatment, a graphite furnace atomic absorption spectrophotometer is used for determining lead in the sample. The method for determining the lead content in the industrial hemp processing extract through microwave digestion-graphite furnace atomic absorption comprises the following steps of 1, sample preparation; 2, preparation of a lead standard solution; 3, instrument setting; and 4, determination of lead in a standard substance and the sample.
