Extraction of chromium-DCTA complex with trioctylmonomethylammonium chloride (Aliquat-336).
The violet complex formed between chromium(III) DCTA can be quantitatively extracted by Aliquat-336 in chloroform as [Cr(DCTA)] [Aliquat-336]. The conditions for quantitative extraction have been established. The method facilitates the determination of chromium in the presence of other coloured cations.
