White pollution caused by the massive discharges of waste expanded polystyrene (WEPS)
has become a critical global issue, so the effective conversion of WEPS is of great …

Molecularly imprinting on covalent organic frameworks (MI-COF) is a promising way to
prepare selective adsorbents for effective extraction of fluoroquinolones (FQs). However, the …

A novel hypercrosslinked polymer (API-HCP) was synthesized using as monomer for the first
time. API-HCP exhibited high adsorption affinity toward chlorophenols due to the hydrogen …
