ZIF-8 prepared in ionic liquid microemulsions for efficient capture of phosphate from water
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.
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.
