Description
A novel combined technology involving electrospinning, and hydrothermal tactics was developed to fabricate polyvinyl alcohol/polyacrylic acid (PVA/PAA) superhydrophilic nanofibers supported on montmorillonite (MMT) or zeolite. A series of structural characterizations and activity measurements demonstrate that the montmorillonite or zeolite support can significantly decrease the mean nanofiber diameter, resulting in more abundant active sites toward the adsorption of uranium. The maximum monolayer sorption capacity for MMT/PVA/PAA and zeolite/PVA/PAA nanofibers reached as high as 170.53 and 205.75 mg/g, respectively. Five adsorption and desorption cycle experiments demonstrated that the synthetic materials possessed good renewable performance. (author)
