A molecularly imprinted (MIP) film was made by photo radical polymerization on a plastic substrate and used to remove organic sulfur compounds from gasoline fuel. The removal of these compounds reduces the emission of sulfur oxide gases, which are responsible for the formation of acid rain. Optimization of the polymeric films included the selection of the functional monomers and solvents. The adsorption studies of the film, including adsorption kinetics, were investigated, and analysis was performed using a gas chromatography pulse flame photometric detector (GC-PFPD). Benzothiophene (BT) was selected as an example model of the organic sulfur compound in gasoline. BT-1-Vim-MIP film exhibited the highest binding capacity and imprinting factor compared to NIP among the selected monomers. 1-octanol produces a stable film and is chosen as the most suitable solvent for film preparation compared with other solvents. The adsorption equilibrium for 1-Vim-MIP was achieved within 60 min, and the adsorption capacity (Q) reached 34.2 mg g−1 for the BT compound.

摘要

A molecularly imprinted (MIP) film was made by photo radical polymerization on a plastic substrate and used to remove organic sulfur compounds from gasoline fuel. The removal of these compounds reduces the emission of sulfur oxide gases, which are responsible for the formation of acid rain. Optimization of the polymeric films included the selection of the functional monomers and solvents. The adsorption studies of the film, including adsorption kinetics, were investigated, and analysis was performed using a gas chromatography pulse flame photometric detector (GC-PFPD). Benzothiophene (BT) was selected as an example model of the organic sulfur compound in gasoline. BT-1-Vim-MIP film exhibited the highest binding capacity and imprinting factor compared to NIP among the selected monomers. 1-octanol produces a stable film and is chosen as the most suitable solvent for film preparation compared with other solvents. The adsorption equilibrium for 1-Vim-MIP was achieved within 60 min, and the adsorption capacity (Q) reached 34.2 mg g−1 for the BT compound.
