Protonation of Trioctylamine(TOA) With Sulfuric Acid

Separation of sulfuric acid with TOA from acidic solution for many metals ion recovery through solvent extraction method has been investigated. The effect of concentration of TOA as an extractant and octanol as modifier has been studied. Also the effect of temperature and water adsorption has been studied. An organic phase containingTOA as extractant, octanol as modifier and Kerosene as diluent. Increase in the TOA concentration leads to an increase of the amount of acid extracted in the organic phase. Adsorption of sulfuric acid with TOA is an exothermic reaction.stoichiometric coefficients of sulfuric acid in this reaction has been determinated by slope analysis method. It has been shown that 3 moles of TOA extracts 2moles of sulfuric acid and 3 moles of water.
