Abstract:

The investigation was carried out to estimate the extraction behaviors of Cu and Pb from the binary solution of metal salts with Versatic Acid 10 diluted in benzen.
The experimental data was compared with the theoretical values for the extraction of metal ions.
The experimental results obtained can be summarized as follows:
(1) The observed values for the extraction of Cu and Pb from the mixed solution coincided with the theoretical values for the extraction of Cu and Pb. Therefore, the extraction for separation of Cu and Pb from the binary solution can be estimated by means of theoretical analysis.
(2) The extraction for separation of Cu and Pb from the binary solution was not dependent upon concentration of Pb2+, but increased with increasing concentration of Cu2+ and NO3-.
