Volatile organic compounds (VOCs) with high toxicity and carcinogenicity are emitted from kinds of industries, which endanger human health and the environment. Adsorption is a promising method for the treatment of VOCs due to its low cost and high efficiency. In recent years, activated carbons, zeolites, and mesoporous materials are widely used to remove VOCs because of their high specific surface area and abundant porosity. However, the hydrophilic nature and low desorption rate of those materials limit their commercial application. Furthermore, the adsorption capacities of VOCs still need to be improved. Porous organic polymers (POPs) with extremely high porosity, structural diversity, and hydrophobic have been considered as one of the most promising candidates for VOCs adsorption. This review generalized the superiority of POPs for VOCs adsorption compared to other porous materials and summarized the studies of VOCs adsorption on different types of POPs. Moreover, the mechanism of competitive adsorption between water and VOCs on the POPs was discussed. Finally, a concise outlook for utilizing POPs for VOCs adsorption was discussed, noting areas in which further work is needed to develop the next-generation POPs for practical applications. 相似文献

The highly e cient inorganic polymer flocculants (IPFs) of the ferric-silica system is a new and promising coagulant. Interactions
between ferric species and silica play a large part in the coagulation of suspensions. These e ects are quite distinct from those associated
with polymeric or colloid silica. However, although these species are key to coagulation e ciency, they have not been comprehensively
discussed. A new type of coagulant, poly-silica-ferric-chloride (PFSC), was synthesized by co-polymerization and characterized by
time complexation spectroscopy and photon correlation spectroscopy. Compared with traditional ferric salt, the results indicated that
PFSC had a higher molecular weight, lesser positive charge, lower Feb and higher Fec. The higher the Si/Fe ratio, the higher the silica
and lower the silicac found. The PFSC with appropriate polysilica acid not only obtained better coagulation/flocculation e ciency in
turbidity removal, enhanced the flocculation index (FI) and provided less residual ferric, it also lowered water treatment costs compared
to traditional ferric salt. Results showed that PFSC could remove colloid particles in water by charge neutralization and sweeping,
adsorption bridging mechanism. 相似文献
