摘要

•First report for simultaneous analysis of HAAs and AA in coffee by UHPLC-MS/MS.•QuEChERS and nano-Fe3O4 can remove pigment, caffeoylquinic acid, chlorogenic acid.•The method with favorable robustness, sensitivity and selectivity is easy to implement.•The method is a good tool enabling detection of AA and HAAs in commercial coffee.
