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
