A method for determination of sulfonylurea herbicides (SUHs) in grain was developed by using mesoporous structured molecularly imprinted polymers (M-MIPs) as adsorbents of matrix solid-phase dispersion (MSPD) extraction, coupled with liquid chromatography-tandem mass spectrometry (LC-MS/MS). In this method, M-MIPs were synthesized by selecting chlorimuron-ethyl as template molecule, cetyltrimethylammonium...
In this work, a simple and selective method based on matrix solid phase dispersion (MSPD) using molecularly imprinted polymers (MIPs) as sorbents was successfully developed for the determination of melamine (MEL) in milk powder. The MIPs have been prepared by surface imprinted polymerization method using carbon nanotube (CNT) as support, MEL as template molecule, γ-aminopropyltriethoxysilane as functional...
