## Abstract A new method for glyphosate residue determination in apple has been developed. A SPE cartridge was used to clean up the samples before derivatization. Glyphosate was derivatized with 4‐chloro‐3,5‐dinitrobenzotrifluoride (CNBF) and quantified by reverse ion‐pair liquid chromatography usi
