Industrialization and human activities have led to pollution of ecosystems by metals and dyes, calling for advanced remediation methods. For instance, removal of water pollutants has been recently done using low-cost adsorbents. Here we review adsorbents based on cellulose, zeolites, biochar and nanomaterials. Hybridized nanosorbents show adsorption capacities up to five times higher than single materials, due to the combination of functions such as carboxyl, amino, thiol, hydroxyl, vinyl, metals and phenolics. Integrating metals having high magnetization and superparamagnetic properties improves reusability up to 10 cycles with minimal loss of pollutant removal efficiency.

工业化和人类活动已导致金属和染料污染生态系统，因此需要先进的补救方法。例如，最近已经使用低成本的吸附剂去除了水污染物。在这里，我们将介绍基于纤维素，沸石，生物炭和纳米材料的吸附剂。由于羧基，氨基，硫醇，羟基，乙烯基，金属和酚类等功能的结合，杂交纳米吸附剂的吸附能力比单一材料高出五倍。集成具有高磁化强度和超顺磁性质的金属可提高高达10个循环的可重复使用性，同时将污染物去除效率的损失降至最低。
