The polluted water sources pose a serious issue concerning the various health hazards they bring along. Due to various uncontrolled anthropogenic and industrial activities, a great number of pollutants have gained entry into the water systems. Among all the emerging contaminants, anionic species such as fluoride cause a major role in polluting the water bodies because of its high reactivity with other elements. The need for water remediation has led the research community to come up with several physicochemical and electrochemical methods to remove fluoride contamination. Among the existing methods, biosorption using bio and modified biomaterials has been extensively studied for defluoridation, as they are cheap, easily available and effectively recyclable when compared to other methods for defluoridation. Adding on, these materials are non-toxic and are safe to use compared to many other synthetic materials that are toxic and require high-cost design requirements. This review focuses on the recent developments made in the defluoridation techniques by biosorption using bio and modified biomaterials and defines the current perspectives of fluoride removal specifically using biomaterials.

生物启发的材料，用于水的除氟：综述。

受污染的水源带来了严重的健康危害。由于各种不受控制的人为和工业活动，许多污染物已进入水系统。在所有新出现的污染物中，阴离子物种（例如氟化物）由于其与其他元素的高反应性而在污染水体中起主要作用。水修复的需求已导致研究界提出了几种物理化学和电化学方法来去除氟化物污染。在现有方法中，已广泛研究了使用生物和改性生物材料进行的生物吸附脱氟，因为与其他脱氟方法相比，它们便宜，易于获得且可有效回收。加上 与许多其他有毒且需要高成本设计要求的合成材料相比，这些材料无毒且使用安全。这篇综述着重介绍了使用生物和改性生物材料通过生物吸附进行的脱氟技术的最新进展，并详细介绍了目前特别是使用生物材料去除氟化物的观点。
