SEPARATION AND LIQUID-LIQUID EXTRACTION OF THORIUM (IV) AS SULPHATE COMPLEX WITH SYNERGISTIC MIXTURE OF N-n-OCTYLANILINE AND TRIOCTYLAMINE AS AN EXTRACTANT

Abstract

Extraction of thorium from aqueous sulphuric acid medium with a synergistic mixture of N-n-octylaniline and trioctylamine (TOA) in xylene is reported in this paper. The effects of varying the concentration of sulphuric acid, N-n-octylaniline and trioctylamine on the distribution ratio of Thorium have been studied. Based on the results obtained, the possible extraction mechanism has been discussed. The determination of thorium and its separation from synthetic mixture has been suggested. The method has been extended to the analysis of thorium in monazite sand and gas mantle.
