The covalent triazine framework, CTF-1, served as host material for the in situ synthesis of Fe2 O3 nanoparticles. The composite material consisted of 20 ± 2 m% iron, mainly in γ-Fe2 O3 phase. The resulting γ-Fe2 O3 @CTF-1 was examined for the adsorption of AsIII , AsV and HgII from synthetic solutions and real surface-, ground- and wastewater. The material shows excellent removal efficiencies, independent from the presence of Ca2+ , Mg2+ or natural organic matter and only limited dependency on the presence of phosphate ions...
