Abstract

A high-efficiency adsorbent ZIF-8 was successfully prepared in a microemulsion system provided by an ionic liquid, which showed excellent potential for removing phosphate from water. The properties of the adsorbents were determined by several characterization methods, such as X-ray diffraction (XRD), infrared spectroscopy (FTIR) and Brunauere-Emmette-Teller (BET) et al. The results confirmed that ZIF-8 prepared in the ionic liquid microemulsion (ZIF-8-ILM) has a smaller particle size compared with that prepared in an aqueous solution. Moreover, the ZIF-8-ILM holds a high BET specific surface area and pore volume, as well as the textural meso- and macro-porosities formed by inter-particle voids. Based on these traits, the ZIF-8-ILM exhibit excellent adsorption capacity for phosphate, as evidenced by a maximum adsorption capacity of 178.99 mg/g was obtained. In addition, the capture of phosphate on ZIF-8-ILM was quite quickly and reached equilibrium within 60 min.

Graphical abstract

A high-efficiency adsorbent ZIF-8 was successfully prepared in a microemulsion system provided by an ionic liquid. The ZIF-8 materials prepared not only had high BET specific surface area and pore volume but also exhibited hierarchical pore structure, which showed excellent potential for removing phosphate from water.

在离子液体微乳液中制备ZIF-8，用于从水中高效捕获磷酸盐

在离子液体提供的微乳液体系中成功制备了高效吸附剂ZIF-8，该吸附剂具有良好的脱除水中磷酸盐的潜力。采用x射线衍射(XRD)、红外光谱(FTIR)、Brunauere-Emmette-Teller (BET)等表征方法对吸附剂的性能进行了表征。结果证实，离子液体微乳液(ZIF-8- ilm)中制备的ZIF-8比在水溶液中制备的ZIF-8具有更小的粒径。此外，ZIF-8-ILM具有较高的BET比表面积和孔隙体积，以及由颗粒间空隙形成的细观和宏观孔隙结构。基于这些特性，ZIF-8-ILM对磷酸盐具有良好的吸附能力，最大吸附量为178.99 mg/g。此外，ZIF-8- ilm对磷酸盐的吸附速度非常快，在60分钟内达到平衡。在离子液体提供的微乳液体系中成功制备了高效吸附剂ZIF-8。制备的ZIF-8材料不仅具有较高的BET比表面积和孔隙体积，而且具有层次化的孔隙结构，具有良好的去除水中磷酸盐的潜力。

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
