| Abstract: | Nucleophilic anions such as phenoxide and cyanide dissolved in an aqueous phase were effectively reacted with alkyl halides present in an organic phase containing a phase transfer catalyst. Preliminary data show the concentration of these anions in water decreased from 10,000 ppm to less than 1 ppm in 2–3 h at less than 70 °C. This methodology enables treatment of hazardous anions that are difficult to remove when using a conventional approach. |
