摘要
本文将对六价铬有效的萃取剂TOA(三正辛胺)微胶囊化,制成填充柱型的酸性体系六价铬的富集分离装置。实验结果表明,微胶囊填充柱中每毫升TOA对六价铬的最大萃取容量为158.0g/mL,为纯TOA液相萃取的4.9倍。微胶囊经碱/水洗涤后,可再生使用。
Trioetyl amine (TOA) was microencapsulated on ethyl cellulose for Cr(Ⅵ) extraction in acid medium. An column form apparatus has been assembled. The extractive capacity of the microcapsules was 158. 0mg·mL^(-1),4.9 times that of the pure TOA. The ? crocapsules can be regenerated by NaOH solution and water and used repeatedly.
