Poly glycidyl methacrylate-co-ethylene dimethacrylate porous monolith as a versatile platform for the development of separations and solid-phase extractions in sequential injection analyzers.

We demonstrated that the porous structure and the reactivity of the epoxy group in the poly glycidyl methacrylate-co-ethylene dimethacrylate monolith can be a platform for the development of separation and extraction methods based on sequential injection analysis. The epoxy group was functionalized to produce monoliths affording complexing and ion exchange properties. Derivatization with iminodiacetate and sodium sulfite produced weak and strong cation exchangers, respectively.
