摘要：

The extraction of indium(III) from acidic sulphuric solution by the ionic liquid (PJMTH(+)FISO(4)(-)) was investigated. This ionic liquid was generated by reaction of the primary amine Primene JMT (PJMT) and sulphuric acid solutions. The metal extraction was investigated under various experimental conditions: equilibration time, temperature, metal and sulphuric acid concentrations in the aqueous feed and extractant concentration in the organic solution. Also, the selectivity of the present system against the presence of other metals in the aqueous feed was examined. Indium stripping is effectively done by the use of sulphuric acid solution. Extraction and stripping isotherms were generated within this work.
