Transport of indium(III) using pseudo-emulsion based hollow fiber strip dispersion with ionic liquid RNH3+HSO4-
The transport of indium(III) through pseudo-emulsion based hollow fiber strip dispersion technology was investigated. The extractant being an ionic liquid RNH3+HSO4-, previously generated from the reaction of the primary amine Primene JMT, dissolved in Solvesso 100, and sulphuric acid. The feed solution containing In(III) was flowed through the tube side, and pseudo-emulsion of RNH3+HSO4-/Solvesso 100 and sulphuric acid was passed through the shell side in counter-current mode, using a single fiber contactor for extraction and stripping. Several hydrodynamic and chemical parameters, such as variation in flows, feed pH (0.6-2), indium concentration in feed (0.01-0.1 g L-1), carrier concentration (0.0025-0.25 M), etc., were investigated.
