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。

关键词: 铬离子, 萃取, 三正辛胺, 微胶囊化

Abstract: 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 microcapsules can be regenerated by NaOH solution and water and used repeatedly.

Key words: chromium ion, extraction, trioctyl amine, microcapsulation
