摘要：

The nitrate salts of Ag** plus and Pb**2** plus are extracted into toluene solutions of one of the following macrocycles: dicylohexano-18-crown-6 (DC18C6); 1. 10-dithia-18-crown-6 (2. 2); hexathia-18-crown-6 (HT18C6); or cryptand 2. 2. 1. In addition, the nitrate salt of Cd**2** plus are also extracted into toluene solutions of DC18C6 or DT18C76. Ag** plus , Pb**2** plus , and Cd**2** plus are also extracted into toluene containing di(2-ethylhexyl)phosphoric acid (HDEHP) and toluene containing a combination of HDEHP and one of the macrocycles. Metal ion extraction is synergistic for the systems containing HDEHP and DC18C6, 2. 2, or 2. 2. 1, but is antagonistic for the systems containing HDEHP and DT18C6 or HT18C6.
