Functional Hyper-crosslinked Polypyrene for Reductive Decolorization of Industrial Dyes and Effective Mercury Removal from Aqueous Media |
| 초록 |
A rigid and valuable hyper-crosslinked polymer (HCP) has been synthesized using pyrene, a polycyclic aromatic hydrocarbon (HCPPy). The HCPPy was prepared through a simple one-step Friedel-Crafts alkylation reaction that involves ZnBr2-catalyzed crosslinking in the presence of an external crosslinker. Interestingly, the unreacted bromomethyl groups (−CH2Br) on the surface of HCPPy could be quantified. We aimed at fabricating with disulfide containing cystamine dihydrochloride (Cys-HCPPy). As a fundamental application, the Cys-HCPPy composite was used as a sorbent to remove Hg2+ ions from aqueous media. Thus, at pH 6, the adsorption capacity of mercury ions reached 1124.82 mg g−1 after 24 h. Furthermore, the immobilization of Ag nanoparticles on the surface of Cys-HCPPy (Ag@Cys-HCPPy) enhanced the catalytic properties, which allowed for the reductive decolorization of industrial dyes such as methylene blue, methyl orange, and congo red in the presence of NaBH4 as a reducing agent. |
