摘要 通过研究使用基于液滴的微反应器系统的萃取和反萃取过程，用合适的杯[4]芳烃萃取剂逐步回收银（I）、钯（II）和铂（IV）。使用微反应器系统仅在 4.00 秒内即可从实际废物中提取出最高百分比的银、钯 (100%) 和铂离子 (37.2%)，而批量方法则需要 24 和 72 小时才能达到提取平衡。傅里叶变换红外光谱研究表明，萃取和反萃后，杯[4]芳烃衍生物与金属络合的峰移具有非常好的关系。基于液滴的微反应器系统成为应用于金属回收的有效工具。
ABSTRACT Stepwise recovery of silver(I), palladium(II) and platinum(IV) with suitable calix[4]arene extractants was carried out by investigating the extraction and stripping process using a droplet-based microreactor system. The highest percentages of silver, palladium (100%) and platinum ion (37.2%) were extracted from a real waste only within 4.00s using a microreactor system compared with 24 and 72 h to reach extraction equilibrium in a batch method. Fourier transform infrared spectroscopy studies revealed a very good relation in peak shifts on the metal complexation with calix[4]arene derivatives after extraction and stripping. The droplet-based microreactor system emerges as an effective tool to be applied in metal recovery.
