英文摘要 | macroporous materials are a class of absorbents used for oil spill cleanup. in this article, novel macroporous and hydrophobic polyvinyl formaldehyde (pvf-h) sponges were prepared by the reaction of stearoyl chloride with hydroxyl groups of hydrophilic pvf sponge at different temperatures. attenuated total reflectance-infrared (atr-ir) spectroscopy confirmed the successfully anchoring of hydrophobic stearoyl groups on the pvf networks. scanning electron microscopy (sem) images demonstrated that the as prepared pvf-h had interconnected open cell structures, and mercury intrusion porosimetry indicated that the average pore size ranged from 60 to 90 mu m and porosity was greater than 94.8%. such pvf-h sponges can absorb oil products effectively, such as toluene, n-hexane, kerosene, soybean oil, hydraulic oil, and crude oil up to 13.7 g.g(-1) to 56.6 g.g(-1) and this level of absorption was approximately 2-4 times higher than that absorbed by commercial polypropylene nonwoven mat. in low-viscosity oils, the samples can reach the saturated absorption amount only in 1 min, but in higher-viscosity oils, absorption equilibrium can be reached in 10 min. in a simulated oil slick system, these macroporous and hydrophobic sponges can still maintain high oil absorption capacities within the range of 14.4 g.g(-1) to 57.6 g.g(-1), whereas a relatively low absorption rate (approximately 20 min) indicated high absorption performance and excellent selectivity in the oil-water mixture. in addition, the absorbed oils were collected effectively only through a simple squeeze. the pvf-h sponges were subjected to 35 absorption-squeeze cycles and exhibited good reusability and 90% recovery for oils. the samples prepared at different temperatures differed in their absorption capacities to some extent. however, this new kind of macroporous and pvf-h sponges had excellent absorption performance on oil products. |
