Polyurea-magnetic hierarchical porous composites for profiling of anionic metabolites

Combining powerful adsorption capacity, simple preparation, rapid separation as well as superior stability and recyclability, a polyurea-magnetic hierarchical porous composite has been prepared. It demonstrates efficient physisorption for anionic metabolites in less than one minute and is promising for application to the analysis of a broad range of anionic metabolites in complex matrices. Polyurea-magnetic hierarchical porous composites show excellent physisorption performance for anionic metabolites in complex matrices with simple preparation, rapid separation, superior stability, and recyclability.
