The results showed that at an environmental pH value of 6.O，the CMCFP achieved optimal recoveryefficiency for the six synthetic cathinone analytes，with recovery rates ranging between 71.5% and 107.7%.The most effective elution solvent was found to be ammonia/methanol solution with fraction volumique of 3% .Furthermore，the CMCFP maintained high recovery performance even after five consecutive uses.
