Claim 11:
12. A product analysis method for the metabolic enzyme-induced micro-nano plastic particle biodegradation method according to claim 1, comprising:
step (6), adding the mixed solution incubated for a period of time onto an MTP 384 stainless steel non-polished target plate dropwise;
step (7), placing the MTP 384 stainless steel non-polished target plate in a fume cupboard without adding a matrix, and evaporating a sample naturally; and
step (8), after the sample is dried, placing the MTP 384 stainless steel non-polished target plate on a target holder of a matrix-assisted laser desorption/ionization time of flight mass spectrometer (MALDI-TOF MS), and directly performing a mass spectrometry test on the sample through the MALDI-TOF MS.
