Three kinds of polystyrene-divinylbenzene (PS-DVB) resins were selected to prepare immunoaffinity columns
(IAC) through nitration, amination, activation, and antibody coupling for the simultaneous purification of four Fusarium
toxins, zearalenone, deoxynivalenol, T-2 and HT-2 toxins. Among these, the coupling ratio of Cleanert PS-type PS-DVB
IAC was 97.64% and the absorption of its blank column for samples was the lowest. The recovery of this IAC column at
three spiked concentration levels was in the range of 66.16%–112.80%, and the relative standard deviation was between
3.09% and 12.25%. It can be applied to purify actual samples.

Key words: polystyrene-divinylbenzene (PS-DVB), immunoaffinity columns (IAC), Fusarium toxinsn
