Facile fabrication of magnetic urea-based covalent organic framework for selective and efficient solid-phase extraction of parabens in soft drinks and skin toners.

A novel and efficient adsorbent is vital and of great concern in the extraction and selective enrichment. We reported a facile strategy for the fabrication of novel magnetic urea-based covalent organic frameworks (COF), Fe3O4@TFPBau, by one-pot metho…
