A nanomaterial comprising Fe3O4-modified-carboxylic multi-walled carbon nanotubes (Fe3O4-MWCNTs-COOH) was prepared by a co-precipitation method. Combined with HPLC-photodiode array detector (DAD), Fe3O4-MWCNTs-COOH was used to determine pigments in beverage. Some important parameters that could influence extraction efficiency were optimized. The results indicated that Fe3O4-MWCNTs-COOH combined with HPLC-DAD is a promising solid-phase extraction material for the sample pretreatment in the
