Zusammenfassung:The invention relates to a method for determining dichloropropanol in solid waste, and belongs to the technical field of analytical chemistry. The method for determining dichloropropanol in solid waste provided by the invention comprises the following steps: (1) adding solid waste to be determined, a matrix modifier, an isotope internal standard solution, an N-propylethylenediamine solid adsorbent, reduced graphene oxide and lipophilic synthetic hectorite into a headspace bottle, oscillating, performing ultrasonic treatment, and centrifuging to obtain a sample to be determined; and (2) putting the to-be-detected sample obtained in the step (1) into an automatic headspace sampler, balancing the to-be-detected sample in the automatic headspace sampler, and detecting dichloropropanol in a gas phase through gas chromatography and mass spectrometry. According to the determination method, the to-be-determined solid waste is pretreated, interference of impurities in the solid waste on dichloropropanol determination
