摘要
Protection of the environment from the increasing threats of pollution from several chemical industries in a sustainable way has become a major global challenge. The colored effluents from the textile and dyestuff industries are major sources of pollution, contaminating water bodies. Herein, we have synthesized a covalent organic polymerTBTPACOPhaving a V-shaped Troger's base unit in the framework with the notion that the unique cleft like architecture of TB will infuse porosity and robustness in the amorphous polymeric material. The covalent organic polymer (COP) was used for the adsorption of anionic acid dyes from aqueous effluent. The equilibrium adsorption capacity (q(e)) was found to be 188.96 mg g(-1). The excellent dye adsorption capacity of the COP, adsorbing 95% of an acid dye (Acid Orange II) at room temperature within 70 min, along with its recyclability up to 4 consecutive cycles, makesTBTPACOPan extremely promising material for selective and efficient removal of acid dyes from aqueous effluent.
