Ethyl-bis-triazinylpyridine (Et-BTP) for the separation of americium (III) from trivalent lanthanides using solvent extraction and supported liquid membrane methods

A Bhattacharyya, PK Mohapatra, A Roy, T Gadly… - Hydrometallurgy, 2009 - Elsevier
The present paper deals with the solvent extraction and supported liquid membrane studies
on Ln (III)/An (III) separation using ethyl-bis-triazinylpyridine (Et-BTP) as the extractant. The
solvent extraction studies involved evaluation of a) diluents, b) phase modifiers, c) stripping
agents and d) role of feed acidity. Though reasonably high separation factor values were
obtained when Et-BTP was used along with α-bromo carboxylic acids, the mixtures could not
be used for liquid membrane studies due to unsatisfactory stripping. On the other hand, a …
