Nanocellulose is a renewable material that combines a high surface area with high strength, chemical inertness, and versatile surface chemistry. In this review, we will briefly describe how nanocellulose is produced, and present-in particular, how nanocellulose and its surface modified versions affects the adsorption behavior of important water pollutants, e.g., heavy metal species, dyes, microbes, and organic molecules. The processing of nanocellulose-based membranes and filters for water purification will be described in detail, and the uptake capacity, selectivity, and removal efficiency will also be discussed. The processing and performance of nanocellulose-based membranes, which combine a high removal efficiency with anti-fouling properties, will be highlighted.
纳米纤维素是一种可再生材料，它具有高比表面积、高强度、化学惰性以及多样的表面化学性质。在本综述中，我们将简要描述纳米纤维素的生产过程，尤其要介绍纳米纤维素及其表面改性形式如何影响重要水污染物（如重金属物种、染料、微生物和有机分子）的吸附行为。将详细描述用于水净化的纳米纤维素基膜和过滤器的加工过程，并讨论其吸收容量、选择性和去除效率。将重点介绍兼具高去除效率和抗污染性能的纳米纤维素基膜的加工和性能。
