Abstract

Abstract : High-performance static and dynamic removal of Se(iv ) from environmental water was achieved by using a porous ZrO2 coated fiber membrane. Abstract : Environmental water containing excessive selenium (Se) seriously threatens human health. Hence, it is essential to remove excessive Se from environmental water. In this work, a porous ZrO2 coated fiber membrane (ZrO2 /FM) was prepared in situ for Se(iv ) removal from environmental water. The removal experiments show that ZrO2 /FM possesses excellent removal performance towards Se(iv ). In the static removal experiments, over 90% Se(iv ) can be removed within 60 min by using ZrO2 /FM and the Se(iv ) maximum adsorption capacity by using ZrO2 /FM is calculated to be as high as 17.69 mg g −1 . The rapid and efficient removal performance profits from the abundant active sites and large specific surface area of ZrO2 . Additionally, a simple filter device was designed and developed for dynamic Se(iv ) removal. Up to 93% Se(iv ) can be removed by using the constructed filter device and the Se(iv ) removal efficiency remains more than 65% after five cycles, indicating the excellent dynamic removal performance and reusability of ZrO2 /FM. These results indicate that our proposed ZrO2 /FM has a very appealing application prospect in the field of static and dynamic removal of Se(iv ) from environmental water.
