Abstract

Citric acid is one of the organic acids of which world market is growing every year. This paper proposes reactive extraction of citric acid with trioctylamine as an alternative to the classical method [1]. An experimental setup with solvent recycling is presented. As organic solvents were used: octanol, cyclohexanol, iso-butyl alcohol and paraffin oil. The removal efficiency is enhanced when the reactive extraction is accompanied by back-extraction using sodium carbonate as stripping agent.
