A novel green modified QuEChERS based on green deep eutectic solvents (DES) followed by GC-MS was developed to analyze pesticides in tea samples. Among different tested DESs for the extraction of analytes, ChClPEG (14) DES showed the highest efficiency. Three-dimensional magnetic graphene was functionalized by ChClurea (12) natural DES, characterized and used as sorbent in the in-syringe dispersive micro-SPE to cleanup tea extract. Under optimized conditions, linear range was 0.70-500 μg kg-1. The limits of quantification (0.70-1.90 μg k
