We developed a method for the hydrolysis of amitraz, and its degradation products 2,4-dimethylphenyl-N'-methylformamidine (DMPF) and 2,4-dimethylformamide (DMF) into 2,4-dimethylaniline (DMA), directly from QuEChERS extracts. The hydrolysis product DMA was analysed using liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS/MS) in the

TiO2-codoped [FeII(bpy)3]2+/zeolite Y systems are revealed to be efficient photocatalysts for photochemically enhanced Fenton processes. Preparation, characterization, and tests using 2,4-xylidine as a model pollutant are described, and a first mechanistic hypothesis explaining the rather high photochemical reactivity of the
