[Epub ahead of print]For the first time, a reliable solid-phase extraction (SPE) procedure using iron (II, III) oxide (Fe3O4)/multi-walled carbon nanotube (MWCNT) composite as sorbents was proposed for purification and enrichment of zearalenone (ZEA) and four type A trichothecenes (T-2 toxin (T-2), HT-2 toxin (HT-2), neosolaniol (NEO) and diacetoxyscirpenol (DAS)) in Salviae miltiorrhiza Radix et Rhizoma (Danshen). The Fe3O4/MWCNT composite was synthesized by assembling Fe3O4 with MWCNT by sonication through an "aggregation wrap" mechanism and several key parameters affecting the performance of SPE procedure such as the composition of sample loading solutions, washing and elution solvents were thoroughly investigated.
