Hierarchical porous spheres shaped conjugated microporous polymers for efficient removal of antibiotics from water

Abstract

Two novel conjugated microporous polymers (CMPs) containing dual heteroatom (named as CMPSN) were synthesized by using 4,7-dibromobenzo[c] [1,2,5] thiadiazole and alkynyl monomers as building blocks though Songashira-Hagihara cross-coupling reaction for efficient removal of antibiotics from water. Fourier transform infrared spectroscopy (FTIR), 13C CP/MAS solid-state NMR, ultraviolet adsorption spectrum (UV) and fluorescence spectroscopy were used to confirm the structure of resulting CMPSN. Under our synthesis conditions, CMPSN with interesting morphologies were obtained where macroscopically porous network structure composed by aggregated hierarchically micrometer-sized microporous spheres formed. Employing of tetracycline as model antibiotics, for the first time, the performance of CMPSN for removal of tetracycline from water was systematically investigated. The results of adsorption kinetics of tetracycline show that the adsorption mechanism of resulting polymers follows a pseudo-second-order model. Moreover, the adsorption behavior of CMPSNs for tetracycline is fitted well with Freundlich model. Besides, adsorption thermodynamics indicates that the adsorption is an endothermic process, the temperature is beneficial to adsorption and the adsorption process is spontaneous. The findings obtained from this work make the CMPSN promising candidate for capture of tetracycline, which may open a new opportunity to address theF environmental issues especially for the global scale of severe water pollution arising from antibiotics.
