Waste valorisation through pyrolysis generates solid, liquid and gaseous fractions that need to be deeply characterised in order to try to recover secondary raw materials or chemicals.

A novel magnetic organic polymer Fe₃O₄@SiO₂@Tb–PDAN was designed and synthesized, which was used as an adsorbent for magnetic solid-phase extraction (MSPE) for the determination of 16 MALs.

We designed and fabricated a novel functionalized magnetic covalent organic framework as a magnetic solid-phase extraction (MSPE) absorbent for the determination of 24 quinolones.

A molecularly imprinted polymer membrane (MIPM) was prepared using PVDF as the support and phenytoin (PHT) as a single template. The results indicated that the MIPMs can be used to extract PHT, phenobarbital, and lamotrigine in different matrices.

Ion pair complex formation between fluvoxamine and erythrosine B dye quench the fluorescence of the dye in a concentration dependent profile.
