摘要：

Liquid-liquid extraction of dicyanocobalamin was performed, using quaternary ammonium salts (Aliquat 336) as liquid ion exchangers. A chemical model, taking into account aggregation of the cyanide and dicyanocobalamin ammonium salts in the organic phase, results in quantitative agreement with experimental data, covering the whole concentration range of practical interest.
