Abstract

The unique characteristics of zirconium have made it susceptible to use in the pollutants purification. Although various zirconium-adsorbents have been used to remove fluoride, but no review article examines their perspective of the practical application. This article reviewed defluoridation papers using Zr-adsorbents. The modification of adsorbents with zirconium was found a useful technique to increase the fluoride adsorption capacity. Researchers have modified many materials like activated carbon, zeolite, and activated alumina by zirconium for efficient fluoride removal and among them Zr-doped polypyrrole/Zr iodate composite (183.5 mg/g) and CeO₂-ZrO₂ nanocages (175 mg/g) have a great capacity. Zirconium improves the chemistry and morphology of materials for fluoride adsorption. The Zr-materials were reusable and their mechanisms in fluoride removal were mostly electrostatic and ion exchange. Due to the excellent feature of zirconium, explorations can be continued to provide adsorbents with a higher ability to eliminate fluoride or similar pollutants.

用于水环境除氟的锆基材料:文献综述和科学计量分析

锆的独特特性使其易于用于污染物净化。尽管各种锆吸附剂已被用于除氟，但并没有综述文章探讨其实际应用前景。本文综述了锆吸附剂降氟的相关文献。锆改性吸附剂是提高氟吸附能力的一种有效技术。研究人员已经用锆对活性炭、沸石和活性氧化铝等许多材料进行了改性，以有效去除氟化物，其中锆掺杂的聚吡咯/碘酸锆复合材料（183.5 mg/g）和CeO2-ZrO2纳米笼（175 mg/g）具有很大的容量。锆改善了氟化物吸附材料的化学性质和形态。锆材料是可重复使用的，其除氟机理主要是静电和离子交换。由于锆的优异特性，可以继续探索提供具有更高消除氟化物或类似污染物能力的吸附剂。
