Phthalate detection method and system

The invention provides a phthalate detection method and system, and the method comprises the steps: detecting the type structure of a to-be-detected object containing phthalate through machine vision, and setting a plurality of sampling points of the to-be-detected object containing phthalate, carrying out point-by-point sampling on the structure of the to-be-detected object at the plurality of sampling points of the to-be-detected object with the impurity-removed surface layer through a microgroove refrigeration direct grinding sampler to obtain a plurality of cold direct grinding samples; the method comprises the following steps: respectively carrying out particle size setting particle size screening on a plurality of numbered cold direct grinding samples by using a layer-by-layer diameter selection particle sieve, and extracting by using a Soxhlet extraction method by using toluene as an extraction reagent to obtain a plurality of numbered Soxhlet extraction samples to be detected; the method comprises the
