中文摘要：由于自然和人为活动造成饮用水中氟污染已经被认为是世界范围内人体健康的一个主要威胁。除氟技术中，吸附过程被广泛研究，特别是在具有矿物成分或改性表面吸附剂时能够提供令人满意的结果。在此综述中汇集了一系列各文献中提及的各种不同吸附剂和它们在不同条件下的吸附容量成果（pH，初始氟浓度，温度，接触时间，吸附剂表面电荷，等），文献中氟去除的可行性已附上了氟去除吸附测试的准备工作。从查阅文献的结果来看，不同的吸附剂都具有良好的除氟潜力。然而，仍然需要在商业规模上找出这样发展成熟、实用的吸附剂，从而改善污染的控制。

Abstract：Fluoride contamination in drinking water due to natural and anthropogenic activities has been recognizedas one of the major problems worldwide imposing a serious threat to human health.Among several treatmenttechnologies applied for fluoride removal, adsorption process has been explored widely and offerssatisfactory results especially with mineral-based and/or surface modified adsorbents.In this review, anextensive list of various adsorbents from literature has been compiled and their adsorption capacitiesunder various conditions (pH, initial fluoride concentration, temperature, contact time, adsorbent surfacecharge, etc.) for fluoride removal as available in the literature are presented along with highlightingand discussing the key advancement on the preparation of novel adsorbents tested so far for fluorideremoval. It is evident from the literature survey that various adsorbents have shown good potential forthe removal of fluoride. However, still there is a need to find out the practical utility of such developedadsorbents on a commercial scale, leading to the improvement of pollution control.
