Recyclable triptycene-based oligomers for selective cationic dye adsorption
Two triptycene-based porous oligomers (TP1 and TP2) having high BET surface areas (up to 509 m2 g−1) and pore volumes (up to 0.64 cm3 g−1) were synthesized in an aqueous medium and characterized by using diverse analytical methods. The inclusion of triptycene moieties rendered permanent porosity to the oligomers. TP1 showed high efficiency towards the removal of cationic dyes with over 80 % MEB and 78 % RB removal within 20 min from the initial concentration of 5 mg L−1 by using only 2 mg of the oligomer. The results obtained with such minute quantity of the oligomer indicated high sensitivity of the oligomer towards dye adsorption. The maximum adsorption capacities of TP1 and TP2 at room temperature were 283 mg g−1 and 278 mg g−1 for MEB and 654 mg g−1 and 649 mg g−1 for RB, respectively. TPs selectively adsorbed the cationic dyes from a binary mixture of cationic and anionic dyes, reflecting selectivity of the oligomers towards cationic dyes. Both TP1 and TP2 exhibited good recyclability up to five times without any substantial loss of the adsorption capacity.
期刊介绍:
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
