TiO2@MOF-919(Fe–Cu) as a sorbent for the extraction of benzoylurea pesticides from irrigation water and fruit juices

The TiO 2 @MOF-919(Fe–Cu) solid-phase extraction material was prepared by growing MOF-919(Fe–Cu) in situ on three-dimensional radial TiO 2 microspheres by a simple solvothermal method.
