The solubility of tri-n-octylamine (TOA) in water and phosphoric acid is reported. Equilibration is achieved by circulating the solutioin through PVC pieces saturated with the absorbed amine in a glass tube. The dissolved TOA is determined by capillary gas chromatography which can detect amine concentrations down to 10 μg l−1. The solubility of TOA in water is 0.039 mg l−1 and in 5.5 M phosphoric acid 0.82 mg l−1; these values are much lower than those reported in the literature.
