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.
