Trögers Base Functionalized Recyclable Porous Covalent Organic Polymer (COP) for the Dye Adsorption from Water
Protection of the environment from the uprising threats of pollution from several chemical industries in a sustainable way has become the major global challenge. The colored effluents from the textile and dyestuff industries are the major sources of pollution, contaminating the water bodies. Herein, we have synthesized a covalent organic polymer TBTPACOP having a V-shaped Tröger’s base unit into 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 the aqueous effluent. The equilibrium adsorption capacity (qe) was found to be 188.96 mg/g. The excellent dye adsorp-tion capacity of the COP by adsorbing 95% of the acid dye (Acid Orange II) at room temperature within 70 mins, along with its recyclability up to 4 consecutive cycles, makes TBTPACOP an extremely promising material for selective and efficient removal of acid dyes from the aqueous effluent.
