Preparation of Petaloid TPEE@AlOOH Nanofibers with Cr (VI)-Removal Capacity

Abstract

Hexavalent chromium (Cr (VI)) is a highly toxic pollutant which is harmful to marine organisms as well as humanity. Removing Cr (VI) from water is a hot-spot in environmental remediation. In this work, a novel kind of composite nano¯bers membrane (thermal plastic elastomer ester (TPEE)@AlOOH) was¯rst proposed by a simple method, based on a hybrid strategy composed of electrospinning and hydrothermal method. The obtained nano¯brous membrane was turned out to be a petaloid structure, which can enlarge the speci¯c surface area of electrospun¯bers. Furthermore, the Cr (VI) removal experiments suggested that the obtained nano¯brous membrane showed a high and fast e±ciency, a stable recyclable property for the Cr (VI) removal. Therefore, such a novel nano¯brous membrane can be potentially widely used in Cr (VI) removal.
