Microwave test method for determining content of harmful substances in plastic package material

The invention discloses a microwave test method for determining the content of harmful substances in a plastic package material, which comprises the following steps of cleaning and drying the plastic package material, then jointly placing the plastic package material and extract solvent in a glass bottle, sealing the glass bottle and enabling the glass bottle to serve as a test unit; placing the test unit into a microwave oven, selecting function power and function time of microwave, and then starting a microware function; after a microwave acceleration extracting test is finished, the solvent is concentrated to an appropriate concentration, and determining the content of the harmful substances in the plastic package material through quantifying and nature determination analysis on the harmful substances in extract through a gas chromatograph or a liquid chromatograph. The microwave test method for determining the content of harmful substances in the plastic package material is fast, convenient and short in time duration. After a plastic package material test sample in the test unit is affected by the microwave, the dissolving speed of the harmful substances can be greatly accelerated, and the time duration of the detection can be greatly shortened. The microwave test method for determining the content of harmful substances in the plastic package material is high in flexibility and can fast determine the content of majority types of harmful substances in the plastic package material.
