Selective magnetic nanographene oxide solid‐phase extraction with high‐performance liquid chromatography and fluorescence detection for the determination of zearalenone in corn samples

A magnetic nanographene oxide sorbent as a selective sorbent for the magnetic solid‐phase extraction combined with high‐performance liquid chromatography and fluorescence detection was developed and proved to be a robust method for zearalenone determination in corn samples. Optimum extraction of zea...
