J. Sep. Sci. 2016, 39, 910–917 DOI: 10.1002/jssc.201501129 A simple method for determination of neoniconoid pesticides in tea infusion based on mesoporous silica SBA–15–NH2 and graphene oxide combined with UPLC–MS/MS was successfully developed. The SBA–15–NH2 has been proved to be an efficient adsorbent for removal of polyphenols from tea infusion. Graphene oxide exhibits very rapid adsorption rate and high adsorption capacities for neonicotinoids. Our study provides an efficient method to address the tea safety control regarding neoniconoids in tea infusion.
