A magnetic graphene-like MoS 2 nanocomposite for simultaneous preconcentration of multi-residue herbicides prior to UHPLC with ion trap mass spectrometric detection
TL;DR: The nanocomposite was employed as a sorbent for magnetic solid-phase extraction (MSPE) of eight triazine and ten sulfonylurea herbicides from environmental water and corn samples and quantified by ultra-high performance liquid chromatography combined with ion trap mass spectrometry and electrospray ionization.
