Abstract

Abstract : A robust, cationic, porous organic polymer (C-NSANaph -HCP@Br), which exhibits excellent adsorption capacities for organic dyes and Cr2 O7 2− in water with rapid adsorption rates, excellent selectivity and good recyclability, is reported. Abstract : The construction of efficient adsorption materials for the removal of pollutants from water is of primary importance for environmental protection. Here, we present a novel cationic porous organic polymer C-NSANaph HCP@Br, that features a permanent porosity with a high surface area and moderate pore volume, and exhibits excellent chemical stability. More importantly, the new cationic network was found to be an excellent platform for the removal of anionic organic dyes and Cr2 O7 2− from water with rapid adsorption rates, excellent selectivity and high efficiency, as well as good recyclability.
